The 10BASE-T1L (Clause 146) is a long reach +PHY supporting full duplex point-to-point operation over 1 km of single +balanced pair of conductors. The 10BASE-T1S (Clause 147) is a short reach +PHY supporting full / half duplex point-to-point operation over 15 m of +single balanced pair of conductors, or half duplex multidrop bus +operation over 25 m of single balanced pair of conductors. + +Furthermore, the IEEE 802.3cg project defines the new Physical Layer +Collision Avoidance (PLCA) Reconciliation Sublayer (Clause 148) meant to +provide improved determinism to the CSMA/CD media access method. PLCA +works in conjunction with the 10BASE-T1S PHY operating in multidrop mode. + +The aforementioned PHYs are intended to cover the low-speed / low-cost +applications in industrial and automotive environment. The large number +of pins (16) required by the MII interface, which is specified by the +IEEE 802.3 in Clause 22, is one of the major cost factors that need to be +addressed to fulfil this objective. + +The MAC-PHY solution integrates an IEEE Clause 4 MAC and a 10BASE-T1x PHY +exposing a low pin count Serial Peripheral Interface (SPI) to the host +microcontroller. This also enables the addition of Ethernet functionality +to existing low-end microcontrollers which do not integrate a MAC +controller. + +Overview +-------- + +The MAC-PHY is specified to carry both data (Ethernet frames) and control +(register access) transactions over a single full-duplex serial peripheral +interface. + +Protocol Overview +----------------- + +Two types of transactions are defined in the protocol: data transactions +for Ethernet frame transfers and control transactions for register +read/write transfers. A chunk is the basic element of data transactions +and is composed of 4 bytes of overhead plus 64 bytes of payload size for +each chunk. Ethernet frames are transferred over one or more data chunks. +Control transactions consist of one or more register read/write control +commands. + +SPI transactions are initiated by the SPI host with the assertion of CSn +low to the MAC-PHY and ends with the deassertion of CSn high. In between +each SPI transaction, the SPI host may need time for additional +processing and to setup the next SPI data or control transaction. + +SPI data transactions consist of an equal number of transmit (TX) and +receive (RX) chunks. Chunks in both transmit and receive directions may +or may not contain valid frame data independent from each other, allowing +for the simultaneous transmission and reception of different length +frames. + +Each transmit data chunk begins with a 32-bit data header followed by a +data chunk payload on MOSI. The data header indicates whether transmit +frame data is present and provides the information to determine which +bytes of the payload contain valid frame data. + +In parallel, receive data chunks are received on MISO. Each receive data +chunk consists of a data chunk payload ending with a 32-bit data footer. +The data footer indicates if there is receive frame data present within +the payload or not and provides the information to determine which bytes +of the payload contain valid frame data. + +Reference +--------- + +10BASE-T1x MAC-PHY Serial Interface Specification, + +Link: https://opensig.org/download/document/OPEN_Alliance_10BASET1x_MAC-PHY_Serial_Interface_V1.1.pdf + +Hardware Architecture +--------------------- + +.. code-block:: none + + +----------+ +-------------------------------------+ + | | | MAC-PHY | + | |<---->| +-----------+ +-------+ +-------+ | + | SPI Host | | | SPI Slave | | MAC | | PHY | | + | | | +-----------+ +-------+ +-------+ | + +----------+ +-------------------------------------+ + +Software Architecture +--------------------- + +.. code-block:: none + + +----------------------------------------------------------+ + | Networking Subsystem | + +----------------------------------------------------------+ + / \ / \ + | | + | | + \ / | + +----------------------+ +-----------------------------+ + | MAC Driver |<--->| OPEN Alliance TC6 Framework | + +----------------------+ +-----------------------------+ + / \ / \ + | | + | | + | \ / + +----------------------------------------------------------+ + | SPI Subsystem | + +----------------------------------------------------------+ + / \ + | + | + \ / + +----------------------------------------------------------+ + | 10BASE-T1x MAC-PHY Device | + +----------------------------------------------------------+ + +Implementation +-------------- + +MAC Driver +~~~~~~~~~~ + +- Probed by SPI subsystem. + +- Initializes OA TC6 framework for the MAC-PHY. + +- Registers and configures the network device. + +- Sends the tx ethernet frames from n/w subsystem to OA TC6 framework. + +OPEN Alliance TC6 Framework +~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +- Initializes PHYLIB interface. + +- Registers mac-phy interrupt. + +- Performs mac-phy register read/write operation using the control + transaction protocol specified in the OPEN Alliance 10BASE-T1x MAC-PHY + Serial Interface specification. + +- Performs Ethernet frames transaction using the data transaction protocol + for Ethernet frames specified in the OPEN Alliance 10BASE-T1x MAC-PHY + Serial Interface specification. + +- Forwards the received Ethernet frame from 10Base-T1x MAC-PHY to n/w + subsystem. + +Data Transaction +~~~~~~~~~~~~~~~~ + +The Ethernet frames that are typically transferred from the SPI host to +the MAC-PHY will be converted into multiple transmit data chunks.

Parity bit calculated over the receive data footer. + Method used is odd parity. + +SPI host will initiate the data receive transaction based on the receive +chunks available in the MAC-PHY which is provided in the receive chunk +footer (RCA - Receive Chunks Available). SPI host will create data invalid +transmit data chunks (empty chunks) or data valid transmit data chunks in +case there are valid Ethernet frames to transmit to the MAC-PHY. The +receive chunks available in MAC-PHY can be read either from the Buffer +Status Register or footer. + +In case the previous data footer had no receive data chunks available and +once the receive data chunks become available again for reading, the +MAC-PHY interrupt is asserted to SPI host. On reception of the first data +header this interrupt will be deasserted and the received footer for the +first data chunk will have the receive chunks available information. + +MAC-PHY Interrupt +~~~~~~~~~~~~~~~~~ + +The MAC-PHY interrupt is asserted when the following conditions are met. + +Receive chunks available - This interrupt is asserted when the previous +data footer had no receive data chunks available and once the receive +data chunks become available for reading. On reception of the first data +header this interrupt will be deasserted. + +Transmit chunk credits available - This interrupt is asserted when the +previous data footer indicated no transmit credits available and once the +transmit credits become available for transmitting transmit data chunks. +On reception of the first data header this interrupt will be deasserted. + +Extended status event - This interrupt is asserted when the previous data +footer indicated no extended status and once the extended event become +available.

Specifies the number of registers to read/write. + This field is interpreted as the number of registers + minus 1 allowing for up to 128 consecutive registers read + or written starting at the address specified in ADDR. A + length of zero shall read or write a single register. + +P (Bit 0) - Parity. Parity bit calculated over the control command header. + Method used is odd parity. + +Control transactions consist of one or more control commands. Control +commands are used by the SPI host to read and write registers within the +MAC-PHY. Each control commands are composed of a 4 bytes control command +header followed by register write data in case of control write command. + +The MAC-PHY ignores the final 4 bytes of data from the SPI host at the end +of the control write command. The control write command is also echoed +from the MAC-PHY back to the SPI host to identify which register write +failed in case of any bus errors. The echoed Control write command will +have the first 4 bytes unused value to be ignored by the SPI host +followed by 4 bytes echoed control header followed by echoed register +write data. Control write commands can write either a single register or +multiple consecutive registers. When multiple consecutive registers are +written, the address is automatically post-incremented by the MAC-PHY. +Writing to any unimplemented or undefined registers shall be ignored and +yield no effect. + +The MAC-PHY ignores all data from the SPI host following the control +header for the remainder of the control read command. The control read +command is also echoed from the MAC-PHY back to the SPI host to identify +which register read is failed in case of any bus errors. The echoed +Control read command will have the first 4 bytes of unused value to be +ignored by the SPI host followed by 4 bytes echoed control header followed +by register read data. Control read commands can read either a single +register or multiple consecutive registers. When multiple consecutive +registers are read, the address is automatically post-incremented by the +MAC-PHY.

A VM cannot be changed from a CoCo VM to a normal VM, +or vice versa, after it is created. + +Operational Modes +----------------- +Hyper-V CoCo VMs can run in two modes. The mode is selected when the VM is +created and cannot be changed during the life of the VM. + +* Fully-enlightened mode. In this mode, the guest operating system is + enlightened to understand and manage all aspects of running as a CoCo VM. + +* Paravisor mode. In this mode, a paravisor layer between the guest and the + host provides some operations needed to run as a CoCo VM. The guest operating + system can have fewer CoCo enlightenments than is required in the + fully-enlightened case. + +Conceptually, fully-enlightened mode and paravisor mode may be treated as +points on a spectrum spanning the degree of guest enlightenment needed to run +as a CoCo VM. Fully-enlightened mode is one end of the spectrum. A full +implementation of paravisor mode is the other end of the spectrum, where all +aspects of running as a CoCo VM are handled by the paravisor, and a normal +guest OS with no knowledge of memory encryption or other aspects of CoCo VMs +can run successfully. However, the Hyper-V implementation of paravisor mode +does not go this far, and is somewhere in the middle of the spectrum. Some +aspects of CoCo VMs are handled by the Hyper-V paravisor while the guest OS +must be enlightened for other aspects. Unfortunately, there is no +standardized enumeration of feature/functions that might be provided in the +paravisor, and there is no standardized mechanism for a guest OS to query the +paravisor for the feature/functions it provides. The understanding of what +the paravisor provides is hard-coded in the guest OS. + +Paravisor mode has similarities to the `Coconut project`_, which aims to provide +a limited paravisor to provide services to the guest such as a virtual TPM. +However, the Hyper-V paravisor generally handles more aspects of CoCo VMs +than is currently envisioned for Coconut, and so is further toward the "no +guest enlightenments required" end of the spectrum. + +.. _Coconut project: https://github.com/coconut-svsm/svsm + +In the CoCo VM threat model, the paravisor is in the guest security domain +and must be trusted by the guest OS. By implication, the hypervisor/VMM must +protect itself against a potentially malicious paravisor just like it +protects against a potentially malicious guest. + +The hardware architectural approach to fully-enlightened vs. paravisor mode +varies depending on the underlying processor. + +* With AMD SEV-SNP processors, in fully-enlightened mode the guest OS runs in + VMPL 0 and has full control of the guest context. In paravisor mode, the + guest OS runs in VMPL 2 and the paravisor runs in VMPL 0. The paravisor + running in VMPL 0 has privileges that the guest OS in VMPL 2 does not have. + Certain operations require the guest to invoke the paravisor. Furthermore, in + paravisor mode the guest OS operates in "virtual Top Of Memory" (vTOM) mode + as defined by the SEV-SNP architecture. This mode simplifies guest management + of memory encryption when a paravisor is used. + +* With Intel TDX processor, in fully-enlightened mode the guest OS runs in an + L1 VM. In paravisor mode, TD partitioning is used. The paravisor runs in the + L1 VM, and the guest OS runs in a nested L2 VM. + +Hyper-V exposes a synthetic MSR to guests that describes the CoCo mode. This +MSR indicates if the underlying processor uses AMD SEV-SNP or Intel TDX, and +whether a paravisor is being used. It is straightforward to build a single +kernel image that can boot and run properly on either architecture, and in +either mode. + +Paravisor Effects +----------------- +Running in paravisor mode affects the following areas of generic Linux kernel +CoCo VM functionality: + +* Initial guest memory setup. When a new VM is created in paravisor mode, the + paravisor runs first and sets up the guest physical memory as encrypted. The + guest Linux does normal memory initialization, except for explicitly marking + appropriate ranges as decrypted (shared). In paravisor mode, Linux does not + perform the early boot memory setup steps that are particularly tricky with + AMD SEV-SNP in fully-enlightened mode. + +* #VC/#VE exception handling. In paravisor mode, Hyper-V configures the guest + CoCo VM to route #VC and #VE exceptions to VMPL 0 and the L1 VM, + respectively, and not the guest Linux. Consequently, these exception handlers + do not run in the guest Linux and are not a required enlightenment for a + Linux guest in paravisor mode. + +* CPUID flags. Both AMD SEV-SNP and Intel TDX provide a CPUID flag in the + guest indicating that the VM is operating with the respective hardware + support. While these CPUID flags are visible in fully-enlightened CoCo VMs, + the paravisor filters out these flags and the guest Linux does not see them. + Throughout the Linux kernel, explicitly testing these flags has mostly been + eliminated in favor of the cc_platform_has() function, with the goal of + abstracting the differences between SEV-SNP and TDX. But the + cc_platform_has() abstraction also allows the Hyper-V paravisor configuration + to selectively enable aspects of CoCo VM functionality even when the CPUID + flags are not set. The exception is early boot memory setup on SEV-SNP, which + tests the CPUID SEV-SNP flag. But not having the flag in Hyper-V paravisor + mode VM achieves the desired effect or not running SEV-SNP specific early + boot memory setup. + +* Device emulation. In paravisor mode, the Hyper-V paravisor provides + emulation of devices such as the IO-APIC and TPM. Because the emulation + happens in the paravisor in the guest context (instead of the hypervisor/VMM + context), MMIO accesses to these devices must be encrypted references instead + of the decrypted references that would be used in a fully-enlightened CoCo + VM. The __ioremap_caller() function has been enhanced to make a callback to + check whether a particular address range should be treated as encrypted + (private). See the "is_private_mmio" callback. + +* Encrypt/decrypt memory transitions. In a CoCo VM, transitioning guest + memory between encrypted and decrypted requires coordinating with the + hypervisor/VMM. This is done via callbacks invoked from + __set_memory_enc_pgtable(). In fully-enlightened mode, the normal SEV-SNP and + TDX implementations of these callbacks are used. In paravisor mode, a Hyper-V + specific set of callbacks is used. These callbacks invoke the paravisor so + that the paravisor can coordinate the transitions and inform the hypervisor + as necessary. See hv_vtom_init() where these callback are set up. + +* Interrupt injection. In fully enlightened mode, a malicious hypervisor + could inject interrupts into the guest OS at times that violate x86/x64 + architectural rules. For full protection, the guest OS should include + enlightenments that use the interrupt injection management features provided + by CoCo-capable processors. In paravisor mode, the paravisor mediates + interrupt injection into the guest OS, and ensures that the guest OS only + sees interrupts that are "legal". The paravisor uses the interrupt injection + management features provided by the CoCo-capable physical processor, thereby + masking these complexities from the guest OS. + +Hyper-V Hypercalls +------------------ +When in fully-enlightened mode, hypercalls made by the Linux guest are routed +directly to the hypervisor, just as in a non-CoCo VM. But in paravisor mode, +normal hypercalls trap to the paravisor first, which may in turn invoke the +hypervisor. But the paravisor is idiosyncratic in this regard, and a few +hypercalls made by the Linux guest must always be routed directly to the +hypervisor. These hypercall sites test for a paravisor being present, and use +a special invocation sequence. See hv_post_message(), for example. + +Guest communication with Hyper-V +-------------------------------- +Separate from the generic Linux kernel handling of memory encryption in Linux +CoCo VMs, Hyper-V has VMBus and VMBus devices that communicate using memory +shared between the Linux guest and the host. This shared memory must be +marked decrypted to enable communication. Furthermore, since the threat model +includes a compromised and potentially malicious host, the guest must guard +against leaking any unintended data to the host through this shared memory. + +These Hyper-V and VMBus memory pages are marked as decrypted: + +* VMBus monitor pages + +* Synthetic interrupt controller (synic) related pages (unless supplied by + the paravisor) + +* Per-cpu hypercall input and output pages (unless running with a paravisor) + +* VMBus ring buffers. The direct mapping is marked decrypted in + __vmbus_establish_gpadl(). The secondary mapping created in + hv_ringbuffer_init() must also include the "decrypted" attribute. + +When the guest writes data to memory that is shared with the host, it must +ensure that only the intended data is written. Padding or unused fields must +be initialized to zeros before copying into the shared memory so that random +kernel data is not inadvertently given to the host. + +Similarly, when the guest reads memory that is shared with the host, it must +validate the data before acting on it so that a malicious host cannot induce +the guest to expose unintended data. Doing such validation can be tricky +because the host can modify the shared memory areas even while or after +validation is performed. For messages passed from the host to the guest in a +VMBus ring buffer, the length of the message is validated, and the message is +copied into a temporary (encrypted) buffer for further validation and +processing. The copying adds a small amount of overhead, but is the only way +to protect against a malicious host. See hv_pkt_iter_first(). + +Many drivers for VMBus devices have been "hardened" by adding code to fully +validate messages received over VMBus, instead of assuming that Hyper-V is +acting cooperatively. Such drivers are marked as "allowed_in_isolated" in the +vmbus_devs[] table. Other drivers for VMBus devices that are not needed in a +CoCo VM have not been hardened, and they are not allowed to load in a CoCo +VM. See vmbus_is_valid_offer() where such devices are excluded. + +Two VMBus devices depend on the Hyper-V host to do DMA data transfers: +storvsc for disk I/O and netvsc for network I/O. storvsc uses the normal +Linux kernel DMA APIs, and so bounce buffering through decrypted swiotlb +memory is done implicitly. netvsc has two modes for data transfers. The first +mode goes through send and receive buffer space that is explicitly allocated +by the netvsc driver, and is used for most smaller packets. These send and +receive buffers are marked decrypted by __vmbus_establish_gpadl(). Because +the netvsc driver explicitly copies packets to/from these buffers, the +equivalent of bounce buffering between encrypted and decrypted memory is +already part of the data path. The second mode uses the normal Linux kernel +DMA APIs, and is bounce buffered through swiotlb memory implicitly like in +storvsc. + +Finally, the VMBus virtual PCI driver needs special handling in a CoCo VM. +Linux PCI device drivers access PCI config space using standard APIs provided +by the Linux PCI subsystem. On Hyper-V, these functions directly access MMIO +space, and the access traps to Hyper-V for emulation. But in CoCo VMs, memory +encryption prevents Hyper-V from reading the guest instruction stream to +emulate the access. So in a CoCo VM, these functions must make a hypercall +with arguments explicitly describing the access. See +_hv_pcifront_read_config() and _hv_pcifront_write_config() and the +"use_calls" flag indicating to use hypercalls. + +load_unaligned_zeropad() +------------------------ +When transitioning memory between encrypted and decrypted, the caller of +set_memory_encrypted() or set_memory_decrypted() is responsible for ensuring +the memory isn't in use and isn't referenced while the transition is in +progress. The transition has multiple steps, and includes interaction with +the Hyper-V host. The memory is in an inconsistent state until all steps are +complete. A reference while the state is inconsistent could result in an +exception that can't be cleanly fixed up. + +However, the kernel load_unaligned_zeropad() mechanism may make stray +references that can't be prevented by the caller of set_memory_encrypted() or +set_memory_decrypted(), so there's specific code in the #VC or #VE exception +handler to fixup this case. But a CoCo VM running on Hyper-V may be +configured to run with a paravisor, with the #VC or #VE exception routed to +the paravisor. There's no architectural way to forward the exceptions back to +the guest kernel, and in such a case, the load_unaligned_zeropad() fixup code +in the #VC/#VE handlers doesn't run. + +To avoid this problem, the Hyper-V specific functions for notifying the +hypervisor of the transition mark pages as "not present" while a transition +is in progress. If load_unaligned_zeropad() causes a stray reference, a +normal page fault is generated instead of #VC or #VE, and the page-fault- +based handlers for load_unaligned_zeropad() fixup the reference. When the +encrypted/decrypted transition is complete, the pages are marked as "present" +again. See hv_vtom_clear_present() and hv_vtom_set_host_visibility(). diff --git a/Documentation/virt/hyperv/index.rst b/Documentation/virt/hyperv/index.rst index de447e11b4a5..79bc4080329e 100644 --- a/Documentation/virt/hyperv/index.rst +++ b/Documentation/virt/hyperv/index.rst @@ -11,3 +11,4 @@ Hyper-V Enlightenments vmbus clocks vpci + coco diff --git a/MAINTAINERS b/MAINTAINERS index 87f9ff0d1649..0b1c49bf558d 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -7473,8 +7473,8 @@ S: Maintained T: git https://gitlab.freedesktop.org/drm/misc/kernel.git F: Documentation/devicetree/bindings/display/bridge/ F: drivers/gpu/drm/bridge/ +F: drivers/gpu/drm/display/drm_bridge_connector.c F: drivers/gpu/drm/drm_bridge.c -F: drivers/gpu/drm/drm_bridge_connector.c F: include/drm/drm_bridge.h F: include/drm/drm_bridge_connector.h @@ -14987,6 +14987,13 @@ L: [email protected] S: Maintained F: drivers/net/ethernet/microchip/lan743x_* +MICROCHIP LAN8650/1 10BASE-T1S MACPHY ETHERNET DRIVER +M: Parthiban Veerasooran <[email protected]> +S: Maintained +F: Documentation/devicetree/bindings/net/microchip,lan8650.yaml +F: drivers/net/ethernet/microchip/lan865x/lan865x.c + MICROCHIP LAN87xx/LAN937x T1 PHY DRIVER M: Arun Ramadoss <[email protected]> @@ -17120,6 +17127,14 @@ L: [email protected] S: Supported F: drivers/infiniband/ulp/opa_vnic +OPEN ALLIANCE 10BASE-T1S MACPHY SERIAL INTERFACE FRAMEWORK +M: Parthiban Veerasooran <[email protected]> +S: Maintained +F: Documentation/networking/oa-tc6-framework.rst +F: drivers/include/linux/oa_tc6.h +F: drivers/net/ethernet/oa_tc6.c + OPEN FIRMWARE AND FLATTENED DEVICE TREE M: Rob Herring <[email protected]> M: Saravana Kannan <[email protected]> @@ -18426,6 +18441,7 @@ L: [email protected] S: Maintained F: Documentation/devicetree/bindings/net/pse-pd/ F: drivers/net/pse-pd/ +F: net/ethtool/pse-pd.c PSTORE FILESYSTEM M: Kees Cook <[email protected]> @@ -2,7 +2,7 @@ VERSION = 6 PATCHLEVEL = 11 SUBLEVEL = 0 -EXTRAVERSION = -rc6 +EXTRAVERSION = -rc7 NAME = Baby Opossum Posse # *DOCUMENTATION* diff --git a/arch/alpha/include/uapi/asm/socket.h b/arch/alpha/include/uapi/asm/socket.h index e94f621903fe..251b73c5481e 100644 --- a/arch/alpha/include/uapi/asm/socket.h +++ b/arch/alpha/include/uapi/asm/socket.h @@ -140,6 +140,12 @@ #define SO_PASSPIDFD 76 #define SO_PEERPIDFD 77 +#define SO_DEVMEM_LINEAR 78 +#define SCM_DEVMEM_LINEAR SO_DEVMEM_LINEAR +#define SO_DEVMEM_DMABUF 79 +#define SCM_DEVMEM_DMABUF SO_DEVMEM_DMABUF +#define SO_DEVMEM_DONTNEED 80 + #if !defined(__KERNEL__) #if __BITS_PER_LONG == 64 diff --git a/arch/arm64/boot/dts/rockchip/rk3328-rock-pi-e.dts b/arch/arm64/boot/dts/rockchip/rk3328-rock-pi-e.dts index a608a219543e..3e08e2fd0a78 100644 --- a/arch/arm64/boot/dts/rockchip/rk3328-rock-pi-e.dts +++ b/arch/arm64/boot/dts/rockchip/rk3328-rock-pi-e.dts @@ -387,7 +387,7 @@ pmic { pmic_int_l: pmic-int-l { - rockchip,pins = <2 RK_PA6 RK_FUNC_GPIO &pcfg_pull_up>; + rockchip,pins = <0 RK_PA2 RK_FUNC_GPIO &pcfg_pull_up>; }; }; diff --git a/arch/arm64/boot/dts/rockchip/rk3399-puma.dtsi b/arch/arm64/boot/dts/rockchip/rk3399-puma.dtsi index ccbe3a7a1d2c..d24444cdf54a 100644 --- a/arch/arm64/boot/dts/rockchip/rk3399-puma.dtsi +++ b/arch/arm64/boot/dts/rockchip/rk3399-puma.dtsi @@ -154,6 +154,22 @@ }; }; +&gpio3 { + /* + * The Qseven BIOS_DISABLE signal on the RK3399-Q7 keeps the on-module + * eMMC and SPI flash powered-down initially (in fact it keeps the + * reset signal asserted).
