2025-02-15Merge tag 'trace-ring-buffer-v6.14-rc2' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull trace ring buffer fixes from Steven Rostedt: - Enable resize on mmap() error When a process mmaps a ring buffer, its size is locked and resizing is disabled. But if the user passes in a wrong parameter, the mmap() can fail after the resize was disabled and the mmap() exits with error without reenabling the ring buffer resize. This prevents the ring buffer from ever being resized after that. Reenable resizing of the ring buffer on mmap() error. - Have resizing return proper error and not always -ENOMEM If the ring buffer is mmapped by one task and another task tries to resize the buffer it will error with -ENOMEM. This is confusing to the user as there may be plenty of memory available. Have it return the error that actually happens (in this case -EBUSY) where the user can understand why the resize failed. - Test the sub-buffer array to validate persistent memory buffer On boot up, the initialization of the persistent memory buffer will do a validation check to see if the content of the data is valid, and if so, it will use the memory as is, otherwise it re-initializes it. There's meta data in this persistent memory that keeps track of which sub-buffer is the reader page and an array that states the order of the sub-buffers. The values in this array are indexes into the sub-buffers. The validator checks to make sure that all the entries in the array are within the sub-buffer list index, but it does not check for duplications. While working on this code, the array got corrupted and had duplicates, where not all the sub-buffers were accounted for. This passed the validator as all entries were valid, but the link list was incorrect and could have caused a crash. The corruption only produced incorrect data, but it could have been more severe. To fix this, create a bitmask that covers all the sub-buffer indexes and set it to all zeros. While iterating the array checking the values of the array content, have it set a bit corresponding to the index in the array. If the bit was already set, then it is a duplicate and mark the buffer as invalid and reset it. - Prevent mmap()ing persistent ring buffer The persistent ring buffer uses vmap() to map the persistent memory. Currently, the mmap() logic only uses virt_to_page() to get the page from the ring buffer memory and use that to map to user space. This works because a normal ring buffer uses alloc_page() to allocate its memory. But because the persistent ring buffer use vmap() it causes a kernel crash. Fixing this to work with vmap() is not hard, but since mmap() on persistent memory buffers never worked, just have the mmap() return -ENODEV (what was returned before mmap() for persistent memory ring buffers, as they never supported mmap. Normal buffers will still allow mmap(). Implementing mmap() for persistent memory ring buffers can wait till the next merge window. - Fix polling on persistent ring buffers There's a "buffer_percent" option (default set to 50), that is used to have reads of the ring buffer binary data block until the buffer fills to that percentage. The field "pages_touched" is incremented every time a new sub-buffer has content added to it. This field is used in the calculations to determine the amount of content is in the buffer and if it exceeds the "buffer_percent" then it will wake the task polling on the buffer. As persistent ring buffers can be created by the content from a previous boot, the "pages_touched" field was not updated. This means that if a task were to poll on the persistent buffer, it would block even if the buffer was completely full. It would block even if the "buffer_percent" was zero, because with "pages_touched" as zero, it would be calculated as the buffer having no content. Update pages_touched when initializing the persistent ring buffer from a previous boot. * tag 'trace-ring-buffer-v6.14-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: ring-buffer: Update pages_touched to reflect persistent buffer content tracing: Do not allow mmap() of persistent ring buffer ring-buffer: Validate the persistent meta data subbuf array tracing: Have the error of __tracing_resize_ring_buffer() passed to user ring-buffer: Unlock resize on mmap error
2025-02-15ring-buffer: Update pages_touched to reflect persistent buffer contentSteven Rostedt
The pages_touched field represents the number of subbuffers in the ring buffer that have content that can be read. This is used in accounting of "dirty_pages" and "buffer_percent" to allow the user to wait for the buffer to be filled to a certain amount before it reads the buffer in blocking mode. The persistent buffer never updated this value so it was set to zero, and this accounting would take it as it had no content. This would cause user space to wait for content even though there's enough content in the ring buffer that satisfies the buffer_percent.

It is rather trivial to allow this, but for now just disable mmap() of instances that have their ring buffer from the reserve_mem option. If an mmap() is performed on a persistent buffer it will return -ENODEV just like it would if the .mmap field wasn't defined in the file_operations structure.

2025-02-15tegra210-adma: fix 32-bit x86 buildLinus Torvalds
The Tegra210 Audio DMA controller driver did a plain divide: page_no = (res_page->start - res_base->start) / cdata->ch_base_offset; which causes problems on 32-bit x86 configurations that have 64-bit resource sizes: x86_64-linux-ld: drivers/dma/tegra210-adma.o: in function `tegra_adma_probe': tegra210-adma.c:(.text+0x1322): undefined reference to `__udivdi3' because gcc doesn't generate the trivial code for a 64-by-32 divide, turning it into a function call to do a full 64-by-64 divide. And the kernel intentionally doesn't provide that helper function, because 99% of the time all you want is the narrower version. Of course, tegra210 is a 64-bit architecture and the 32-bit x86 build is purely for build testing, so this really is just about build coverage failure. But build coverage is good. Side note: div_u64() would be suboptimal if you actually have a 32-bit resource_t, so our "helper" for divides are admittedly making it harder than it should be to generate good code for all the possible cases. At some point, I'll consider 32-bit x86 so entirely legacy that I can't find it in myself to care any more, and we'll just add the __udivdi3 library function. But for now, the right thing to do is to use "div_u64()" to show that you know that you are doing the simpler divide with a 32-bit number. And the build error enforces that. While fixing the build issue, also check for division-by-zero, and for overflow. Which hopefully cannot happen on real production hardware, but the value of 'ch_base_offset' can definitely be zero in other places.

2025-02-15kbuild: fix linux-headers package build when $(CC) cannot link userspaceMasahiro Yamada
Since commit 5f73e7d0386d ("kbuild: refactor cross-compiling linux-headers package"), the linux-headers Debian package fails to build when $(CC) cannot build userspace applications, for example, when using toolchains installed by the 0day bot. The host programs in the linux-headers package should be rebuilt using the disto's cross-compiler, ${DEB_HOST_GNU_TYPE}-gcc instead of $(CC). Hence, the variable 'CC' must be expanded in this shell script instead of in the top-level Makefile. Commit f354fc88a72a ("kbuild: install-extmod-build: add missing quotation marks for CC variable") was not a correct fix because CC="ccache gcc" should be unrelated when rebuilding userspace tools.

[1] MAKEFLAGS puts all single-letter options into the first word, and that word will be empty if no single-letter options were given. [2] However, this breaks if MAKEFLAGS=<value> is given on the command line. The tools/ and tools/% targets set MAKEFLAGS=<value> on the command line, which breaks the following code in tools/scripts/Makefile.include: short-opts := $(firstword -$(MAKEFLAGS)) If MAKEFLAGS really needs modification, it should be done through the environment variable, as follows: MAKEFLAGS=<value> $(MAKE) ... That said, I question whether modifying MAKEFLAGS is necessary here. The only flag we might want to exclude is --no-print-directory, as the tools build system changes the working directory. However, people might find the "Entering/Leaving directory" logs annoying. I simply removed the offending MAKEFLAGS=<value>.

2025-02-15arm64: dts: exynos: gs101: add reboot-mode support (SYSIP_DAT0)André Draszik
syscon-reboot-mode can be used to indicate the reboot mode for the bootloader. While not sufficient for all boot modes, the boot loader does use SYSIP_DAT0 (PMU + 0x0810) to determine some of the actions it should take. This change helps it deciding what to do in those cases. For complete support, we'll also have to write the boot mode to an NVMEM storage location, but we have no upstream driver for that yet. Nevertheless, this patch is a step towards full support for the boot mode. Note1: Android also uses 'shutdown,thermal' and shutdown,thermal,battery', but that can not be described in DT as ',' is used to denote vendor prefixes. I've left them out from here for that reason. Note2: downstream / bootloader recognizes one more mode: 'dm-verity device corrupted' with value 0x50, but we can not describe that in DT using a property name due to the space, so it's been left out from here as well. This string appears to come from drivers/md/dm-verity-target.c and should probably be changed there in a follow-up patch, so that it can be used in reboot-mode nodes like this one here.

For power off, downstream only clears bit 8 and leaves all other bits untouched, whereas this here ends up setting bit 8 and clearing all others, due to how sysconf-poweroff parses the DT. I noticed this discrepancy while debugging some reboot related differences between up- and downstream and it's useful to align the behaviour here. Note: for reboot downstream seems to be incorrectly writing 0x00000002 and not just setting bit 1 (which is the only R/W bit in this register), so we keep that one as-is here.

2025-02-14x86/sev: Fix broken SNP support with KVM module built-inAshish Kalra
Fix issues with enabling SNP host support and effectively SNP support which is broken with respect to the KVM module being built-in. SNP host support is enabled in snp_rmptable_init() which is invoked as device_initcall(). SNP check on IOMMU is done during IOMMU PCI init (IOMMU_PCI_INIT stage). And for that reason snp_rmptable_init() is currently invoked via device_initcall() and cannot be invoked via subsys_initcall() as core IOMMU subsystem gets initialized via subsys_initcall(). Now, if kvm_amd module is built-in, it gets initialized before SNP host support is enabled in snp_rmptable_init() : [ 10.131811] kvm_amd: TSC scaling supported [ 10.136384] kvm_amd: Nested Virtualization enabled [ 10.141734] kvm_amd: Nested Paging enabled [ 10.146304] kvm_amd: LBR virtualization supported [ 10.151557] kvm_amd: SEV enabled (ASIDs 100 - 509) [ 10.156905] kvm_amd: SEV-ES enabled (ASIDs 1 - 99) [ 10.162256] kvm_amd: SEV-SNP enabled (ASIDs 1 - 99) [ 10.171508] kvm_amd: Virtual VMLOAD VMSAVE supported [ 10.177052] kvm_amd: Virtual GIF supported ... ...

The document being referred to above: https://www.amd.com/content/dam/amd/en/documents/processor-tech-docs/revision-guides/57095-PUB_1_01.pdf To summarize, with kvm_amd module being built-in, KVM/SVM initialization happens before host SNP is enabled and this SVM initialization sets VM_HSAVE_PA to non-zero, which then triggers a #GP when SYSCFG.SNPEn is being set and this will subsequently cause SNP_INIT(_EX) to fail with INVALID_CONFIG error as SYSCFG[SnpEn] is not set on all CPUs. Essentially SNP host enabling code should be invoked before KVM initialization, which is currently not the case when KVM is built-in. Add fix to call snp_rmptable_init() early from iommu_snp_enable() directly and not invoked via device_initcall() which enables SNP host support before KVM initialization with kvm_amd module built-in. Add additional handling for `iommu=off` or `amd_iommu=off` options. Note that IOMMUs need to be enabled for SNP initialization, therefore, if host SNP support is enabled but late IOMMU initialization fails then that will cause PSP driver's SNP_INIT to fail as IOMMU SNP sanity checks in SNP firmware will fail with invalid configuration error as below: [ 9.723114] ccp 0000:23:00.1: sev enabled [ 9.727602] ccp 0000:23:00.1: psp enabled [ 9.732527] ccp 0000:a2:00.1: enabling device (0000 -> 0002) [ 9.739098] ccp 0000:a2:00.1: no command queues available [ 9.745167] ccp 0000:a2:00.1: psp enabled [ 9.805337] ccp 0000:23:00.1: SEV-SNP: failed to INIT rc -5, error 0x3 [ 9.866426] ccp 0000:23:00.1: SEV API:1.53 build:5 Fixes: c3b86e61b756 ("x86/cpufeatures: Enable/unmask SEV-SNP CPU feature") Co-developed-by: Sean Christopherson <seanjc@google.com> Signed-off-by: Sean Christopherson <seanjc@google.com> Co-developed-by: Vasant Hegde <vasant.hegde@amd.com> Signed-off-by: Vasant Hegde <vasant.hegde@amd.com> Cc: <Stable@vger.kernel.org> Signed-off-by: Ashish Kalra <ashish.kalra@amd.com> Acked-by: Joerg Roedel <jroedel@suse.de> Message-ID: <138b520fb83964782303b43ade4369cd181fdd9c.1739226950.git.ashish.kalra@amd.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

Jaguar The Pre-ICT tester adapter connects to RK3588 Jaguar SBC through its proprietary Mezzanine connector. It exposes a PCIe Gen2 1x M.2 connector and two proprietary camera connectors. Support for the latter will come once the rest of the camera stack is supported. Additionally, the adapter loops some GPIOs together as well as route some GPIOs to power rails. This adapter is used for manufacturing RK3588 Jaguar to be able to test the Mezzanine connector is properly soldered.

2025-02-14arm64: dts: rockchip: add overlay tests for Rock 5B PCIe overlaysQuentin Schulz
According to commit 40658534756f ("arm64: dts: rockchip: Add rock5b overlays for PCIe endpoint mode"), Rock 5B can operate in PCIe endpoint mode. For that to work, the rk3588-rock-5b-pcie-ep.dtbo overlay needs to be applied on Rock 5B base Device Tree. If that Rock 5B is connected to another Rock 5B, the latter needs to apply the rk3588-rock-5b-pcie-srns.dtbo overlay. In order to make sure the overlays are still valid in the future, let's add a validation test by applying the overlays on top of the main base at build time.

2025-02-14arm64: dts: rockchip: add overlay test for Edgeble NCM6A/NCM6BQuentin Schulz
The Edgeble NCM6A/NCM6B can have WiFi modules connected and this is handled via an overlay (commit 951d6aaa37fe ("arm64: dts: rockchip: Add Edgeble NCM6A WiFi6 Overlay")). Despite the name of the overlay, it applies to both NCM6A and NCM6B[1]. In order to make sure the overlay is still valid in the future, let's add a validation test by applying the overlay on top of the main bases at build time.
