2024-09-01Remove *.orig pattern from .gitignoreLaurent Pinchart1-1/+0
Commit 3f1b0e1f2875 (".gitignore update") added *.orig and *.rej patterns to .gitignore in v2.6.23. The commit message didn't give a rationale. Later on, commit 1f5d3a6b6532 ("Remove *.rej pattern from .gitignore") removed the *.rej pattern in v2.6.26, on the rationale that *.rej files indicated something went really wrong and should not be ignored. The *.rej files are now shown by `git status`, which helps located conflicts when applying patches and lowers the probability that they will go unnoticed. It is however still easy to overlook the *.orig files which slowly polute the source tree. That's not as big of a deal as not noticing a conflict, but it's still not nice. Drop the *.orig pattern from .gitignore to avoid this and help keep the source tree clean. Signed-off-by: Laurent Pinchart <[email protected]> [[email protected]: I do not have a strong opinion about this. Perhaps some people may have a different opinion. If you are someone who wants to ignore *.orig, it is likely you would want to do so across all projects. Then, $XDG_CONFIG_HOME/git/ignore would be more suitable for your needs. gitignore(5) suggests, "Patterns which a user wants Git to ignore in all situations generally go into a file specified by core.excludesFile in the user's ~/.gitconfig". Please note that you cannot do the opposite; if *.orig is ignored by the project's .gitignore, you cannot override the decision because $XDG_CONFIG_HOME/git/ignore has a lower priority. If *.orig is sitting on the fence, I'd leave it to the users. ] Signed-off-by: Masahiro Yamada <[email protected]>
2024-09-01kbuild: cross-compile linux-headers package when possibleMasahiro Yamada1-0/+34
A long standing issue in the upstream kernel packaging is that the linux-headers package is not cross-compiled. For example, you can cross-build Debian packages for arm64 by running the following command: $ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- bindeb-pkg However, the generated linux-headers-*_arm64.deb is useless because the host programs in it were built for your build machine architecture (likely x86), not arm64. The Debian kernel maintains its own Makefiles to cross-compile host tools without relying on Kbuild. [1] Instead of adding such full custom Makefiles, this commit adds a small piece of code to cross-compile host programs located under the scripts/ directory. A straightforward solution is to pass HOSTCC=${CROSS_COMPILE}gcc, but it would also cross-compile scripts/basic/fixdep, which needs to be native to process the if_changed_dep macro. (This approach may work under some circumstances; you can execute foreign architecture programs with the help of binfmt_misc because Debian systems enable CONFIG_BINFMT_MISC, but it would require installing QEMU and libc for that architecture.) A trick is to use the external module build (KBUILD_EXTMOD=), which does not rebuild scripts/basic/fixdep. ${CC} needs to be able to link userspace programs (CONFIG_CC_CAN_LINK=y). There are known limitations: - GCC plugins It would possible to rebuild GCC plugins for the target architecture by passing HOSTCXX=${CROSS_COMPILE}g++ with necessary packages installed, but gcc on the installed system emits "cc1: error: incompatible gcc/plugin versions". - objtool and resolve_btfids These are built by the tools build system. They are not covered by the current solution. The resulting linux-headers package is broken if CONFIG_OBJTOOL or CONFIG_DEBUG_INFO_BTF is enabled. I only tested this with Debian, but it should work for other package systems as well.

2024-09-01PCI: qcom: Disable mirroring of DBI and iATU register space in BAR regionPrudhvi Yarlagadda3-15/+61
PARF hardware block which is a wrapper on top of DWC PCIe controller mirrors the DBI and ATU register space. It uses PARF_SLV_ADDR_SPACE_SIZE register to get the size of the memory block to be mirrored and uses PARF_DBI_BASE_ADDR, PARF_ATU_BASE_ADDR registers to determine the base address of DBI and ATU space inside the memory block that is being mirrored. When a memory region which is located above the SLV_ADDR_SPACE_SIZE boundary is used for BAR region then there could be an overlap of DBI and ATU address space that is getting mirrored and the BAR region. This results in DBI and ATU address space contents getting updated when a PCIe function driver tries updating the BAR/MMIO memory region. Reference memory map of the PCIe memory region with DBI and ATU address space overlapping BAR region is as below. |---------------| | | | | ------- --------|---------------| | | |---------------| | | | DBI | | | |---------------|---->DBI_BASE_ADDR | | | | | | | | | PCIe | |---->2*SLV_ADDR_SPACE_SIZE | BAR/MMIO|---------------| | Region | ATU | | | |---------------|---->ATU_BASE_ADDR | | | | PCIe | |---------------| Memory | | DBI | Region | |---------------|---->DBI_BASE_ADDR | | | | | --------| | | | |---->SLV_ADDR_SPACE_SIZE | |---------------| | | ATU | | |---------------|---->ATU_BASE_ADDR | | | | |---------------| | | DBI | | |---------------|---->DBI_BASE_ADDR | | | | | | ----------------|---------------| | | | | | | |---------------| Currently memory region beyond the SLV_ADDR_SPACE_SIZE boundary is not used for BAR region which is why the above mentioned issue is not encountered. This issue is discovered as part of internal testing when we tried moving the BAR region beyond the SLV_ADDR_SPACE_SIZE boundary. Hence we are trying to fix this. As PARF hardware block mirrors DBI and ATU register space after every PARF_SLV_ADDR_SPACE_SIZE (default 0x1000000) boundary multiple, program maximum possible size to this register by writing 0x80000000 to it(it considers only powers of 2 as values) to avoid mirroring DBI and ATU to BAR/MMIO region. Write the physical base address of DBI and ATU register blocks to PARF_DBI_BASE_ADDR (default 0x0) and PARF_ATU_BASE_ADDR (default 0x1000) respectively to make sure DBI and ATU blocks are at expected memory locations. The register offsets PARF_DBI_BASE_ADDR_V2, PARF_SLV_ADDR_SPACE_SIZE_V2 and PARF_ATU_BASE_ADDR are applicable for platforms that use Qcom IP rev 1.9.0, 2.7.0 and 2.9.0. PARF_DBI_BASE_ADDR_V2 and PARF_SLV_ADDR_SPACE_SIZE_V2 are applicable for Qcom IP rev 2.3.3. PARF_DBI_BASE_ADDR and PARF_SLV_ADDR_SPACE_SIZE are applicable for Qcom IP rev 1.0.0, 2.3.2 and 2.4.0. Update init()/post_init() functions of the respective Qcom IP versions to program applicable PARF_DBI_BASE_ADDR, PARF_SLV_ADDR_SPACE_SIZE and PARF_ATU_BASE_ADDR register offsets. Update the SLV_ADDR_SPACE_SZ macro to 0x80000000 to set highest bit in PARF_SLV_ADDR_SPACE_SIZE register. Cache DBI and iATU physical addresses in 'struct dw_pcie' so that pcie_qcom.c driver can program these addresses in the PARF_DBI_BASE_ADDR and PARF_ATU_BASE_ADDR registers.

2024-09-01PCI: qcom: Enumerate endpoints based on Link up event in 'global_irq' interruptManivannan Sadhasivam1-1/+54
Historically, Qcom PCIe RC controllers lacked standard hotplug support. So when an endpoint is attached to the SoC, users have to rescan the bus manually to enumerate the device. But this can be avoided by using the Link up event exposed by the Qcom specific 'global_irq' interrupt. Qcom PCIe RC controllers are capable of generating the 'global' SPI interrupt to the host CPUs. The device driver can use this interrupt to identify events such as PCIe link specific events, safety events etc... One such event is the PCIe Link up event generated when an endpoint is detected on the bus and the Link is 'up'. This event can be used to enumerate the PCIe endpoint devices without user intervention. So add support for capturing the PCIe Link up event using the 'global' interrupt in the driver. Once the Link up event is received, the bus underneath the host bridge is scanned to enumerate PCIe endpoint devices. All of the Qcom SoCs have only one Root Port per controller instance. So only a single 'Link up' event is generated for the PCIe controller.

Currently, the IRQ device name for both of these IRQs doesn't have Qcom specific prefix and PCIe domain number. This causes 2 issues: 1. Pollutes the global IRQ namespace since 'global' is a common name. 2. When more than one EP controller instance is present in the SoC, naming conflict will occur. Hence, add 'qcom_pcie_ep_' prefix and PCIe domain number suffix to the IRQ names to uniquely identify the IRQs and also to fix the above mentioned issues.

2024-09-01PCI: endpoint: Assign PCI domain number for endpoint controllersManivannan Sadhasivam2-0/+16
Right now, PCI endpoint subsystem doesn't assign PCI domain number for the PCI endpoint controllers. But this domain number could be useful to the EPC drivers to uniquely identify each controller based on the hardware instance when there are multiple ones present in an SoC (even multiple RC/EP). So let's make use of the existing pci_bus_find_domain_nr() API to allocate domain numbers based on either devicetree (linux,pci-domain) property or dynamic domain number allocation scheme. It should be noted that the domain number allocated by this API will be based on both RC and EP controllers in a SoC. If the 'linux,pci-domain' DT property is present, then the domain number represents the actual hardware instance of the PCI endpoint controller. If not, then the domain number will be allocated based on the PCI EP/RC controller probe order. If the architecture doesn't support CONFIG_PCI_DOMAINS_GENERIC (rare), then currently a warning is thrown to indicate that the architecture specific implementation is needed.

2024-09-01ARM: dts: imx6: update spdif sound card node propertiesElinor Montmasson12-28/+104
The merge of imx-spdif driver into fsl-asoc-card brought new DT properties that can be used with the "fsl,imx-audio-spdif" compatible: * The "spdif-controller" property from imx-spdif is named "audio-cpu" in fsl-asoc-card. * fsl-asoc-card uses codecs explicitly declared in DT with "audio-codec". With an S/PDIF, codec drivers spdif_transmitter and spdif_receiver should be used. Driver imx-spdif used instead the dummy codec and a pair of boolean properties, "spdif-in" and "spdif-out". While backward compatibility is kept to support properties "spdif-controller", "spdif-in" and "spdif-out", using new properties has several benefits: * "audio-cpu" and "audio-codec" are more generic names reflecting that the fsl-asoc-card driver supports multiple hardware. They are properties already used by devices using the fsl-asoc-card driver. They are also similar to properties of simple-card: "cpu" and "codec". * "spdif-in" and "spdif-out" imply the use of the dummy codec in the driver. However, there are already two codec drivers for the S/PDIF, spdif_transmitter and spdif_receiver. It is better to declare S/PDIF Tx and Rx devices in a DT, and then reference them with "audio-codec" than using the dummy codec. For those reasons, this commit updates in-tree DTs to use the new properties: * Rename "spdif-controller" property to "audio-cpu". * Declare S/PDIF transmitter and/or receiver devices, and use them with the "audio-codec" property instead of "spdif-out" and/or "spdif-in". These modifications were tested only on an imx8mn-evk board. Note that out-of-tree and old DTs are still supported.

2024-08-31bcachefs: Revert lockless buffered IO pathKent Overstreet2-110/+40
We had a report of data corruption on nixos when building installer images. https://github.com/NixOS/nixpkgs/pull/321055#issuecomment-2184131334 It seems that writes are being dropped, but only when issued by QEMU, and possibly only in snapshot mode. It's undetermined if it's write calls are being dropped or dirty folios. Further testing, via minimizing the original patch to just the change that skips the inode lock on non appends/truncates, reveals that it really is just not taking the inode lock that causes the corruption: it has nothing to do with the other logic changes for preserving write atomicity in corner cases. It's also kernel config dependent: it doesn't reproduce with the minimal kernel config that ktest uses, but it does reproduce with nixos's distro config. Bisection the kernel config initially pointer the finger at page migration or compaction, but it appears that was erroneous; we haven't yet determined what kernel config option actually triggers it. Sadly it appears this will have to be reverted since we're getting too close to release and my plate is full, but we'd _really_ like to fully debug it. My suspicion is that this patch is exposing a preexisting bug - the inode lock actually covers very little in IO paths, and we have a different lock (the pagecache add lock) that guards against races with truncate here.

2024-08-31Merge branch 'unmask-dscp-bits'David S. Miller10-16/+25
Ido Schimmel says: ==================== Unmask upper DSCP bits - part 2 tl;dr - This patchset continues to unmask the upper DSCP bits in the IPv4 flow key in preparation for allowing IPv4 FIB rules to match on DSCP. No functional changes are expected. Part 1 was merged in commit ("Merge branch 'unmask-upper-dscp-bits-part-1'"). The TOS field in the IPv4 flow key ('flowi4_tos') is used during FIB lookup to match against the TOS selector in FIB rules and routes. It is currently impossible for user space to configure FIB rules that match on the DSCP value as the upper DSCP bits are either masked in the various call sites that initialize the IPv4 flow key or along the path to the FIB core. In preparation for adding a DSCP selector to IPv4 and IPv6 FIB rules, we need to make sure the entire DSCP value is present in the IPv4 flow key. This patchset continues to unmask the upper DSCP bits, but this time in the output route path. Patches #1-#3 unmask the upper DSCP bits in the various places that invoke the core output route lookup functions directly. Patches #4-#6 do the same in three helpers that are widely used in the output path to initialize the TOS field in the IPv4 flow key. The rest of the patches continue to unmask these bits in call sites that invoke the following wrappers around the core lookup functions: Patch #7 - __ip_route_output_key() Patches #8-#12 - ip_route_output_flow() The next patchset will handle the callers of ip_route_output_ports() and ip_route_output_key(). No functional changes are expected as commit 1fa3314c14c6 ("ipv4: Centralize TOS matching") moved the masking of the upper DSCP bits to the core where 'flowi4_tos' is matched against the TOS selector.
