2023-03-19dyndbg: cleanup dynamic usage in ib_srp.cJason Baron1-22/+37
Currently, in dynamic_debug.h we only provide DEFINE_DYNAMIC_DEBUG_METADATA() and DYNAMIC_DEBUG_BRANCH() definitions if CONFIG_DYNAMIC_CORE is enabled. Thus, drivers such as infiniband srp (see: drivers/infiniband/ulp/srp/ib_srp.c) must provide their own definitions for !CONFIG_DYNAMIC_CORE. Thus, let's move this !CONFIG_DYNAMIC_CORE case into dynamic_debug.h. However, the dynamic debug interfaces should really only be defined if CONFIG_DYNAMIC_DEBUG is set or CONFIG_DYNAMIC_CORE is set along with DYNAMIC_DEBUG_MODULE, (see: Documentation/admin-guide/dynamic-debug-howto.rst). Thus, the undefined case becomes: !((CONFIG_DYNAMIC_DEBUG || (CONFIG_DYNAMIC_CORE && DYNAMIC_DEBUG_MODULE)). With those changes in place, we can remove the !CONFIG_DYNAMIC_CORE case from ib_srp.c This change was prompted by a build breakeage in ib_srp.c stemming from the inclusion of dynamic_debug.h unconditionally in module.h, due to commit 7deabd674988 ("dyndbg: use the module notifier callbacks"). In that case, if we have CONFIG_DYNAMIC_CORE=y and CONFIG_DYNAMIC_DEBUG=n then the definitions for DEFINE_DYNAMIC_DEBUG_METADATA() and DYNAMIC_DEBUG_BRANCH() are defined once in ib_srp.c and then again in the dynamic_debug.h. This had been working prior to the above referenced commit because dynamic_debug.h was only pulled into ib_srp.c conditinally via printk.h if CONFIG_DYNAMIC_DEBUG was set. Also, the exported functions in lib/dynamic_debug.c itself may not have a prototype if CONFIG_DYNAMIC_DEBUG=n and CONFIG_DYNAMIC_CORE=y. This would trigger the -Wmissing-prototypes warning. The exported functions are behind (include/linux/dynamic_debug.h): if defined(CONFIG_DYNAMIC_DEBUG) || \ (defined(CONFIG_DYNAMIC_DEBUG_CORE) && defined(DYNAMIC_DEBUG_MODULE)) Thus, by adding -DDYNAMIC_CONFIG_MODULE to the lib/Makefile we can ensure that the exported functions have a prototype in all cases, since lib/dynamic_debug.c is built whenever CONFIG_DYNAMIC_DEBUG_CORE=y.

2023-03-19net: stmmac: Fix for mismatched host/device DMA address widthJochen Henneberg1-1/+1
Currently DMA address width is either read from a RO device register or force set from the platform data. This breaks DMA when the host DMA address width is <=32it but the device is >32bit. Right now the driver may decide to use a 2nd DMA descriptor for another buffer (happens in case of TSO xmit) assuming that 32bit addressing is used due to platform configuration but the device will still use both descriptor addresses as one address. This can be observed with the Intel EHL platform driver that sets 32bit for addr64 but the MAC reports 40bit. The TX queue gets stuck in case of TCP with iptables NAT configuration on TSO packets. The logic should be like this: Whatever we do on the host side (memory allocation GFP flags) should happen with the host DMA width, whenever we decide how to set addresses on the device registers we must use the device DMA address width. This patch renames the platform address width field from addr64 (term used in device datasheet) to host_addr and uses this value exclusively for host side operations while all chip operations consider the device DMA width as read from the device register.

2023-03-18efi: sysfb_efi: Fix DMI quirks not working for simpledrmHans de Goede1-2/+7
Commit 8633ef82f101 ("drivers/firmware: consolidate EFI framebuffer setup for all arches") moved the sysfb_apply_efi_quirks() call in sysfb_init() from before the [sysfb_]parse_mode() call to after it. But sysfb_apply_efi_quirks() modifies the global screen_info struct which [sysfb_]parse_mode() parses, so doing it later is too late. This has broken all DMI based quirks for correcting wrong firmware efifb settings when simpledrm is used. To fix this move the sysfb_apply_efi_quirks() call back to its old place and split the new setup of the efifb_fwnode (which requires the platform_device) into its own function and call that at the place of the moved sysfb_apply_efi_quirks(pd) calls.

2023-03-17wwan: core: Support slicing in port TX flow of WWAN subsystemhaozhe chang1-0/+11
wwan_port_fops_write inputs the SKB parameter to the TX callback of the WWAN device driver. However, the WWAN device (e.g., t7xx) may have an MTU less than the size of SKB, causing the TX buffer to be sliced and copied once more in the WWAN device driver. This patch implements the slicing in the WWAN subsystem and gives the WWAN devices driver the option to slice(by frag_len) or not. By doing so, the additional memory copy is reduced. Meanwhile, this patch gives WWAN devices driver the option to reserve headroom in fragments for the device-specific metadata.

2023-03-17ptp: kvm: Use decrypted memory in confidential guest on x86Jeremi Piotrowski1-0/+1
KVM_HC_CLOCK_PAIRING currently fails inside SEV-SNP guests because the guest passes an address to static data to the host. In confidential computing the host can't access arbitrary guest memory so handling the hypercall runs into an "rmpfault". To make the hypercall work, the guest needs to explicitly mark the memory as decrypted. Do that in kvm_arch_ptp_init(), but retain the previous behavior for non-confidential guests to save us from having to allocate memory. Add a new arch-specific function (kvm_arch_ptp_exit()) to free the allocation and mark the memory as encrypted again.

2023-03-17cpufreq: amd-pstate: Add guided autonomous modeWyes Karny1-0/+2
From ACPI spec below 3 modes for CPPC can be defined: 1. Non autonomous: OS scaling governor specifies operating frequency/ performance level through `Desired Performance` register and platform follows that. 2. Guided autonomous: OS scaling governor specifies min and max frequencies/ performance levels through `Minimum Performance` and `Maximum Performance` register, and platform can autonomously select an operating frequency in this range. 3. Fully autonomous: OS only hints (via EPP) to platform for the required energy performance preference for the workload and platform autonomously scales the frequency. Currently (1) is supported by amd_pstate as passive mode, and (3) is implemented by EPP support. This change is to support (2). In guided autonomous mode the min_perf is based on the input from the scaling governor. For example, in case of schedutil this value depends on the current utilization. And max_perf is set to max capacity. To activate guided auto mode ``amd_pstate=guided`` command line parameter has to be passed in the kernel.

2023-03-17driver core: class: specify the module owner in __class_register()Greg Kroah-Hartman1-4/+5
There's no need to manually have to set the module owner of a class, the compiler should do it automatically for you, so add a module * to the __class_register() function and allow it to set the module owner automatically. This will let us move the module pointer out of struct class eventually, as it should not be embedded in there if we wish for it to be a read-only structure eventually. And, funny story, this module pointer isn't even being used for anything, so while we will keep it around for now, it's not like it even matters. Cc: "Rafael J.

IOMMU and SVA-capable devices know nothing about LAM and only expect canonical addresses. An attempt to pass down tagged pointer will lead to address translation failure. By default do not allow to enable both LAM and use SVA in the same process. The new ARCH_FORCE_TAGGED_SVA arch_prctl() overrides the limitation. By using the arch_prctl() userspace takes responsibility to never pass tagged address to the device. Signed-off-by: Kirill A.

2023-03-16iommu/sva: Replace pasid_valid() helper with mm_valid_pasid()Kirill A. Shutemov2-10/+7
Kernel has few users of pasid_valid() and all but one checks if the process has PASID allocated. The helper takes ioasid_t as the input. Replace the helper with mm_valid_pasid() that takes mm_struct as the argument. The only call that checks PASID that is not tied to mm_struct is open-codded now. This is preparatory patch. It helps avoid ifdeffery: no need to dereference mm->pasid in generic code to check if the process has PASID. Signed-off-by: Kirill A.

2023-03-16mm: Introduce untagged_addr_remote()Kirill A. Shutemov2-11/+22
untagged_addr() removes tags/metadata from the address and brings it to the canonical form. The helper is implemented on arm64 and sparc. Both of them do untagging based on global rules. However, Linear Address Masking (LAM) on x86 introduces per-process settings for untagging. As a result, untagged_addr() is now only suitable for untagging addresses for the current proccess. The new helper untagged_addr_remote() has to be used when the address targets remote process. It requires the mmap lock for target mm to be taken. Signed-off-by: Kirill A.
