[PATCH v2 0/9] KVM RISC-V Conditional Operations

by Anup Patel

This series extends KVM RISC-V to allow Guest/VM discover and use conditional operations related ISA extensions (namely XVentanaCondOps and Zicond). To try these patches, use KVMTOOL from riscv_zbx_zicntr_smstateen_condops_v1 branch at: https://github.com/avpatel/kvmtool.git These patches are based upon the latest riscv_kvm_queue and can also be found in the riscv_kvm_condops_v2 branch at: https://github.com/avpatel/linux.git Changes since v1: - Rebased the series on riscv_kvm_queue - Split PATCH1 and PATCH2 of v1 series into two patches - Added separate test configs for XVentanaCondOps and Zicond in PATCH7 of v1 series. Anup Patel (9): dt-bindings: riscv: Add XVentanaCondOps extension entry RISC-V: Detect XVentanaCondOps from ISA string dt-bindings: riscv: Add Zicond extension entry RISC-V: Detect Zicond from ISA string RISC-V: KVM: Allow XVentanaCondOps extension for Guest/VM RISC-V: KVM: Allow Zicond extension for Guest/VM KVM: riscv: selftests: Add senvcfg register to get-reg-list test KVM: riscv: selftests: Add smstateen registers to get-reg-list test KVM: riscv: selftests: Add condops extensions to get-reg-list test .../devicetree/bindings/riscv/extensions.yaml | 13 ++++ arch/riscv/include/asm/hwcap.h | 2 + arch/riscv/include/uapi/asm/kvm.h | 2 + arch/riscv/kernel/cpufeature.c | 2 + arch/riscv/kvm/vcpu_onereg.c | 4 ++ .../selftests/kvm/riscv/get-reg-list.c | 71 +++++++++++++++++++ 6 files changed, 94 insertions(+) -- 2.34.1

[PATCH] drivers: base: test: Make property entry API test modular

by Geert Uytterhoeven

There is no reason why the KUnit Tests for the property entry API can only be built-in. Add support for building these tests as a loadable module, like is supported by most other tests.

[PATCH] selftests/rseq: fix kselftest Clang build warnings

by Justin Stitt

When building with Clang, I am getting many warnings from the selftests/rseq tree. Here's one such example from rseq tree: | param_test.c:1234:10: error: address argument to atomic operation must be a pointer to _Atomic type ('intptr_t *' (aka 'long *') invalid) | 1234 | while (!atomic_load(&args->percpu_list_ptr)) {} | | ^ ~~~~~~~~~~~~~~~~~~~~~~ | /usr/local/google/home/justinstitt/repos/tc-build/build/llvm/final/lib/clang/18/include/stdatomic.h:140:29: note: expanded from macro 'atomic_load' | 140 | #define atomic_load(object) __c11_atomic_load(object, __ATOMIC_SEQ_CST) | | ^ ~~~~~~ Use compiler builtins `__atomic_load_n()` and `__atomic_store_n()` with accompanying __ATOMIC_ACQUIRE and __ATOMIC_RELEASE, respectively. This will fix the warnings because the compiler builtins do not expect their arguments to have _Atomic type. This should also make TSAN happier.

[PATCH v3 0/4] kunit: Fix some bugs in kunit

by Jinjie Ruan

The test_cases is not freed in kunit_free_suite_set(). And the copy pointer may be moved in kunit_filter_suites(). The filtered_suite and filtered_suite->test_cases allocated in the last kunit_filter_attr_tests() in last inner for loop may be leaked if kunit_filter_suites() fails. If kunit_filter_suites() succeeds, not only copy but also filtered_suite and filtered_suite->test_cases should be freed. Changes in v3: - Update the kfree_at_end() to use kunit_free_suite_set() for 4th patch. - Update the commit message for the 4th patch. Changes in v2: - Add Reviewed-by. - Add the memory leak backtrace for the 4th patch. - Remove the unused func kernel test robot noticed for the 4th patch. - Update the commit message for the 4th patch.

[PATCH v5 0/8] selftests/resctrl: Rework benchmark command handling

by Ilpo Järvinen

The benchmark command handling (-b) in resctrl selftests is overly complicated code. This series turns the benchmark command immutable to preserve it for all selftests and improves benchmark command related error handling. This series also ends up removing the strcpy() calls which were pointed out earlier. v5: - Fix another off-by-one error - Reorder local var declarations in main() to follow rev. xmas tree v4: - Correct off-by-one error in -b processing - Reordered code in main() to make freeing span_str simpler (in new patch) - Use consistent style for const char * const * v3: - Removed DEFAULT_SPAN_STR for real and the duplicated copy of defines that made to v2 likely due to my incorrect conflict resolutions v2: - Added argument length check into patch 1/7 - Updated also -b line in help message. - Document -b argument related "algorithm" - Use asprintf() to convert defined constant int to string - Improved changelog texts - Added \n to ksft_exit_fail_msg() call messages. - Print DEFAULT_SPAN with %u instead of %zu to avoid need to cast it Ilpo Järvinen (8): selftests/resctrl: Ensure the benchmark commands fits to its array selftests/resctrl: Correct benchmark command help selftests/resctrl: Remove bw_report and bm_type from main() selftests/resctrl: Simplify span lifetime selftests/resctrl: Reorder resctrl FS prep code and benchmark_cmd init selftests/resctrl: Make benchmark command const and build it with pointers selftests/resctrl: Remove ben_count variable selftests/resctrl: Cleanup benchmark argument parsing tools/testing/selftests/resctrl/cache.c | 5 +- tools/testing/selftests/resctrl/cat_test.c | 13 +-- tools/testing/selftests/resctrl/cmt_test.c | 34 ++++-- tools/testing/selftests/resctrl/mba_test.c | 4 +- tools/testing/selftests/resctrl/mbm_test.c | 7 +- tools/testing/selftests/resctrl/resctrl.h | 16 +-- .../testing/selftests/resctrl/resctrl_tests.c | 100 ++++++++---------- tools/testing/selftests/resctrl/resctrl_val.c | 10 +- 8 files changed, 104 insertions(+), 85 deletions(-) -- 2.30.2

[PATCH bpf-next v1] bpf/selftests: improve arg parsing in test_verifier

by Tony Ambardar

Current test_verifier provides little feedback or argument validation, instead silently falling back to running all tests in case of user error or even expected use cases. Trying to do manual exploratory testing, switching between kernel versions (e.g. with varying tests), or working around problematic tests (e.g. kernel hangs/crashes) can be a frustrating experience. Rework argument parsing to be more robust and strict, and provide basic help on errors. Clamp test ranges to valid values and add an option to list available built-in tests ("-l"). Default "test_verifier" behaviour (run all tests) is unchanged and backwards-compatible. Updated examples: $ test_verifier die die die # previously ran all tests Usage: test_verifier -l | [-v|-vv] [<tst_lo> [<tst_hi>]] $ test_verifier 700 9999 # runs test subset from 700 to end Signed-off-by: Tony Ambardar <Tony.Ambardar(a)gmail.com> --- tools/testing/selftests/bpf/test_verifier.c | 54 ++++++++++++--------- 1 file changed, 30 insertions(+), 24 deletions(-) diff --git a/tools/testing/selftests/bpf/test_verifier.c b/tools/testing/selftests/bpf/test_verifier.c index 98107e0452d3..3712b5363f60 100644 --- a/tools/testing/selftests/bpf/test_verifier.c +++ b/tools/testing/selftests/bpf/test_verifier.c @@ -10,9 +10,11 @@ #include <endian.h> #include <asm/types.h> #include <linux/types.h> +#include <linux/minmax.h> #include <stdint.h> #include <stdio.h> #include <stdlib.h> +#include <ctype.h> #include <unistd.h> #include <errno.h> #include <string.h> @@ -1848,36 +1850,40 @@ int main(int argc, char **argv) { unsigned int from = 0, to = ARRAY_SIZE(tests); bool unpriv = !is_admin(); - int arg = 1; - - if (argc > 1 && strcmp(argv[1], "-v") == 0) { + int i, arg = 1; + + while (argc > 1 && *argv[arg] == '-') { + if (strcmp(argv[arg], "-l") == 0) { + for (i = from; i < to; i++) + printf("#%d %s\n", i, tests[i].descr); + return EXIT_SUCCESS; + } else if (strcmp(argv[arg], "-v") == 0) { + verbose = true; + verif_log_level = 1; + } else if (strcmp(argv[arg], "-vv") == 0) { + verbose = true; + verif_log_level = 2; + } else + goto out_help; arg++; - verbose = true; - verif_log_level = 1; argc--; } - if (argc > 1 && strcmp(argv[1], "-vv") == 0) { - arg++; - verbose = true; - verif_log_level = 2; - argc--; - } - - if (argc == 3) { - unsigned int l = atoi(argv[arg]); - unsigned int u = atoi(argv[arg + 1]); - if (l < to && u < to) { - from = l; - to = u + 1; - } - } else if (argc == 2) { - unsigned int t = atoi(argv[arg]); + for (i = 1; i <= 2 && argc > 1; i++, arg++, argc--) { + unsigned int t = min(atoi(argv[arg]), ARRAY_SIZE(tests) - 1); - if (t < to) { + if (!isdigit(*argv[arg])) + goto out_help; + if (i == 1) from = t; - to = t + 1; - } + to = t + 1; + } + + if (argc > 1) { +out_help: + printf("Usage: %s -l | [-v|-vv] [<tst_lo> [<tst_hi>]]\n", + argv[0]); + return EXIT_FAILURE; } unpriv_disabled = get_unpriv_disabled(); -- 2.34.1

For backwards compatibility the kernel config default is disabling the limit (0). Without any limit a malicious actor may OOM a kernel by spamming packets with changing MAC addresses on their bridge port, so allow the bridge creator to limit the number of entries. Currently the manual entries are identified by the bridge flags BR_FDB_LOCAL or BR_FDB_ADDED_BY_USER, atomically bundled under the new flag BR_FDB_DYNAMIC_LEARNED. This means the limit also applies to entries created with BR_FDB_ADDED_BY_EXT_LEARN but none of BR_FDB_LOCAL or BR_FDB_ADDED_BY_USER, e.g. ones added by SWITCHDEV_FDB_ADD_TO_BRIDGE.

Previously we passed garbage. (from review) - Set strict_start_type for br_policy. (from review) - Split out the combined accounting and limit patch, and the netlink patch from the combined patch in v2. (from review) - Count atomically, remove the newly introduced lock.

(from review) - Do not skip decrementing on 0. (from review) - Moved the counters to a conditional hole in struct net_bridge to avoid growing the struct. (from review, it still grows the struct as there are 2 32-bit values) - Add IFLA_BR_FDB_CUR_LEARNED_ENTRIES (from review) - Fix br_get_size() with the added attributes. - Only limit learned entries, rename to *_(CUR|MAX)_LEARNED_ENTRIES. (from review) - Added a default limit in Kconfig. (deemed acceptable in review comments, helps with embedded use-cases where a special purpose kernel is built anyways) - Added an iproute2 patch for easier testing. - Link to v1: https://lore.kernel.org/netdev/20230515085046.4457-1-jnixdorf-oss@avm.de/ Obsolete v1 review comments: - Return better errors to users: Due to limiting the limit to automatically created entries, netlink fdb add requests and changing bridge ports are never rejected, so they do not yet need a more friendly error returned. --- Johannes Nixdorf (6): net: bridge: Set BR_FDB_ADDED_BY_USER early in fdb_add_entry net: bridge: Set strict_start_type for br_policy net: bridge: Track and limit dynamically learned FDB entries net: bridge: Add netlink knobs for number / max learned FDB entries net: bridge: Add a configurable default FDB learning limit selftests: forwarding: bridge_fdb_learning_limit: Add a new selftest include/uapi/linux/if_link.h | 2 + net/bridge/Kconfig | 13 + net/bridge/br_device.c | 2 + net/bridge/br_fdb.c | 42 ++- net/bridge/br_netlink.c | 17 +- net/bridge/br_private.h | 4 + tools/testing/selftests/net/forwarding/Makefile | 3 +- .../net/forwarding/bridge_fdb_learning_limit.sh | 283 +++++++++++++++++++++ 8 files changed, 359 insertions(+), 7 deletions(-) --- base-commit: ce9ecca0238b140b88f43859b211c9fdfd8e5b70 change-id: 20230904-fdb_limit-fae5bbf16c88 Best regards, -- Johannes Nixdorf <jnixdorf-oss(a)avm.de>

[PATCH] kunit: Fix a null-ptr-deref bug in kunit_run_case_catch_errors()

by Jinjie Ruan

Inject fault while probing kunit-test.ko, the below null-ptr-deref occurs. In kunit_run_case_catch_errors(), if the first kunit_try_catch_run() fails in kthread_run(), the kunit_try_run_case() will not run, so the kunit_resource_test_init() and kunit_resource_test_cases() will not run. And if the second call of kunit_try_catch_run() succeeds, it will call kunit_resource_test_exit(), but the test->priv is NULL, call kunit_cleanup() will cause below null-ptr-deref. So just return the error code if the first kunit_try_catch_run() fails.

[PATCH bpf-next v3 0/9] arm32, bpf: add support for cpuv4 insns

by Puranjay Mohan

Changes in V2 -> V3 - Added comments at places where there could be confustion. - In the patch for DIV64, fix the if-else case that would never run. - In the same patch use a single instruction to POP caller saved regs. - Add a patch to change maintainership of ARM32 BPF JIT. Changes in V1 -> V2: - Fix coding style issues. - Don't use tmp variable for src in emit_ldsx_r() as it is redundant. - Optimize emit_ldsx_r() when offset can fit in immediate. Add the support for cpuv4 instructions for ARM32 BPF JIT. 64-bit division was not supported earlier so this series adds 64-bit DIV, SDIV, MOD, SMOD instructions as well. This series needs any one of the patches from [1] to disable zero-extension for BPF_MEMSX to support ldsx. The relevant selftests have passed expect ldsx_insn which needs fentry: Tested on BeagleBone Black (ARMv7-A): [root@alarm del]# echo 1 > /proc/sys/net/core/bpf_jit_enable [root@alarm del]#

[PATCH 0/6] iommufd support allocating nested parent domain

by Yi Liu

IOMMU hardwares that support nested translation would have two stages address translation (normally mentioned as stage-1 and stage-2). The page table formats of the stage-1 and stage-2 can be different. e.g., VT-d has different page table formats for stage-1 and stage-2. Nested parent domain is the iommu domain used to represent the stage-2 translation. In IOMMUFD, both stage-1 and stage-2 translation are tracked as HWPT (a.k.a. iommu domain). Stage-2 HWPT is parent of stage-1 HWPT as stage-1 cannot work alone in nested translation. In the cases of stage-1 and stage-2 page table format are different, the parent HWPT should use exactly the stage-2 page table format. However, the existing kernel hides the format selection in iommu drivers, so the domain allocated via IOMMU_HWPT_ALLOC can use either stage-1 page table format or stage-2 page table format, there is no guarantees for it. To enforce the page table format of the nested parent domain, this series introduces a new iommu op (domain_alloc_user) which can accept user flags to allocate domain as userspace requires. It also converts IOMMUFD to use the new domain_alloc_user op for domain allocation if supported, then extends the IOMMU_HWPT_ALLOC ioctl to pass down a NEST_PARENT flag to allocate a HWPT which can be used as parent. This series implements the new op in Intel iommu driver to have a complete picture. It is a preparation for adding nesting support in IOMMUFD/IOMMU. Complete code can be found: https://github.com/yiliu1765/iommufd/tree/iommufd_alloc_user_v1 Regards, Yi Liu Yi Liu (6): iommu: Add new iommu op to create domains owned by userspace iommufd/hw_pagetable: Use domain_alloc_user op for domain allocation iommufd/hw_pagetable: Accepts user flags for domain allocation iommufd/hw_pagetable: Support allocating nested parent domain iommufd/selftest: Add domain_alloc_user() support in iommu mock iommu/vt-d: Add domain_alloc_user op drivers/iommu/intel/iommu.c | 20 ++++++++++++ drivers/iommu/iommufd/device.c | 2 +- drivers/iommu/iommufd/hw_pagetable.c | 31 ++++++++++++++----- drivers/iommu/iommufd/iommufd_private.h | 3 +- drivers/iommu/iommufd/selftest.c | 16 ++++++++++ include/linux/iommu.h | 8 +++++ include/uapi/linux/iommufd.h | 12 ++++++- tools/testing/selftests/iommu/iommufd.c | 24 +++++++++++--- .../selftests/iommu/iommufd_fail_nth.c | 2 +- tools/testing/selftests/iommu/iommufd_utils.h | 11 +++++-- 10 files changed, 111 insertions(+), 18 deletions(-) -- 2.34.1

[PATCH] selftests/damon: Add executable permission to test scripts

by Juntong Deng

When running the test for the damon subsystem, there are a lot of warnings because test scripts do not have executable permission, for example: Warning: file debugfs_attrs.sh is not executable Warning: file debugfs_schemes.sh is not executable Warning: file debugfs_target_ids.sh is not executable ... This patch adds executable permission to test scripts to eliminate these warnings.

[RFC] selftests: Add dependencies information for kselftest

by Juntong Deng

Most of the tests in kselftest rely on external tools and libraries to run, which means that in order to run the tests effectively we need to have all the dependencies installed first. But unfortunately, there is currently no way to know in advance what tools and libraries the tests in kselftest depend on, and can only be known when a test run fails. For example after running the alsa subsystem test I realized I needed to install the libasound-dev package. This is inefficient for the test of subsystems that require a long time to run. For example, the net subsystem test, which takes more than an hour to run a complete test. I can only know that I need to install numactl, libnuma-dev, ethtool, mausezahn, netsniff-ng, ndisc6, netperf, and other tools after carefully reviewing the results of the tests. I think we should add dependencies information to the Makefile for each subsystem test, either as a comment or as an output target of the Makefile, it would save a lot of time for the people running the tests. I can do this part of the work. Welcome to discuss! Juntong Deng

[PATCH v2] selftests/lkdtm: Disable CONFIG_UBSAN_TRAP in test config

by Ricardo Cañuelo

The lkdtm selftest config fragment enables CONFIG_UBSAN_TRAP to make the ARRAY_BOUNDS test kill the calling process when an out-of-bound access is detected by UBSAN. However, after this [1] commit, UBSAN is triggered under many new scenarios that weren't detected before, such as in struct definitions with fixed-size trailing arrays used as flexible arrays. As a result, CONFIG_UBSAN_TRAP=y has become a very aggressive option to enable except for specific situations. `make kselftest-merge` applies CONFIG_UBSAN_TRAP=y to the kernel config for all selftests, which makes many of them fail because of system hangs during boot. This change removes the config option from the lkdtm kselftest and configures the ARRAY_BOUNDS test to look for UBSAN reports rather than relying on the calling process being killed.

[PATCH v3 00/10] iov_iter: kunit: Cleanup, abstraction and more tests

by David Howells

Hi Jens, Can you consider taking this through the block tree? These patches make some changes to the kunit tests previously added for iov_iter testing, in particular adding testing of UBUF/IOVEC iterators and some benchmarking: (1) Clean up a couple of checkpatch style complaints. (2) Consolidate some repeated bits of code into helper functions and use the same struct to represent straight offset/address ranges and partial page lists. (3) Add a function to set up a userspace VM, attach the VM to the kunit testing thread, create an anonymous file, stuff some pages into the file and map the file into the VM to act as a buffer that can be used with UBUF/IOVEC iterators. I map an anonymous file with pages attached rather than using MAP_ANON so that I can check the pages obtained from iov_iter_extract_pages() without worrying about them changing due to swap, migrate, etc.. [?] Is this the best way to do things? Mirroring execve, it requires a number of extra core symbols to be exported. Should this be done in the core code? (4) Add tests for copying into and out of UBUF and IOVEC iterators. (5) Add tests for extracting pages from UBUF and IOVEC iterators. (6) Add tests to benchmark copying 256MiB to UBUF, IOVEC, KVEC, BVEC and XARRAY iterators. (7) Add a test to bencmark copying 256MiB from an xarray that gets decanted into 256-page BVEC iterators to model batching from the pagecache. (8) Add a test to benchmark copying 256MiB through dynamically allocated 256-page bvecs to simulate bio construction. Example benchmarks output: iov_kunit_benchmark_ubuf: avg 4474 uS, stddev 1340 uS iov_kunit_benchmark_iovec: avg 6619 uS, stddev 23 uS iov_kunit_benchmark_kvec: avg 2672 uS, stddev 14 uS iov_kunit_benchmark_bvec: avg 3189 uS, stddev 19 uS iov_kunit_benchmark_bvec_split: avg 3403 uS, stddev 8 uS iov_kunit_benchmark_xarray: avg 3709 uS, stddev 7 uS I've pushed the patches here also: https://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git/log/?… David Changes ======= ver #3) - #include <linux/personality.h> to get READ_IMPLIES_EXEC. - Add a test to benchmark decanting an xarray into bio_vecs. ver #2) - Use MAP_ANON to make the user buffer if we don't want a list of pages. - KUNIT_ASSERT_NOT_ERR_OR_NULL() doesn't like __user pointers as the condition, so cast. - Make the UBUF benchmark loop, doing an iterator per page so that the overhead from the iterator code is not negligible. - Make the KVEC benchmark use an iovec per page so that the iteration is not not negligible. - Switch the benchmarking to use copy_from_iter() so that only a single page is needed in the userspace buffer (as it can be shared R/O), not 256MiB's worth.

[PATCH v2 0/4] kunit: Fix some bugs in kunit

by Jinjie Ruan

The test_cases is not freed in kunit_free_suite_set(). And the copy pointer may be moved in kunit_filter_suites(). The filtered_suite and filtered_suite->test_cases allocated in the last kunit_filter_attr_tests() in last inner for loop may be leaked if kunit_filter_suites() fails. If kunit_filter_suites() succeeds, not only copy but also filtered_suite and filtered_suite->test_cases should be freed. Changes in v2: - Add Reviewed-by. - Add the memory leak backtrace for the 4th patch. - Remove the unused func kernel test robot noticed for the 4th patch. - Update the commit message for the 4th patch.

[PATCH 0/3] userfaultfd remap option

by Suren Baghdasaryan

This patch series introduces UFFDIO_REMAP feature to userfaultfd, which has long been implemented and maintained by Andrea in his local tree [1], but was not upstreamed due to lack of use cases where this approach would be better than allocating a new page and copying the contents. UFFDIO_COPY performs ~20% better than UFFDIO_REMAP when the application needs pages to be allocated [2]. However, with UFFDIO_REMAP, if pages are available (in userspace) for recycling, as is usually the case in heap compaction algorithms, then we can avoid the page allocation and memcpy (done by UFFDIO_COPY). Also, since the pages are recycled in the userspace, we avoid the need to release (via madvise) the pages back to the kernel [3]. We see over 40% reduction (on a Google pixel 6 device) in the compacting thread’s completion time by using UFFDIO_REMAP vs. UFFDIO_COPY. This was measured using a benchmark that emulates a heap compaction implementation using userfaultfd (to allow concurrent accesses by application threads). More details of the usecase are explained in [3]. Furthermore, UFFDIO_REMAP enables remapping swapped-out pages without touching them within the same vma. Today, it can only be done by mremap, however it forces splitting the vma. Main changes since Andrea's last version [1]: 1. Trivial translations from page to folio, mmap_sem to mmap_lock 2. Replace pmd_trans_unstable() with pte_offset_map_nolock() and handle its possible failure 3. Move pte mapping into remap_pages_pte to allow for retries when source page or anon_vma is contended. Since pte_offset_map_nolock() start RCU read section, we can't block anymore after mapping a pte, so have to unmap the ptesm do the locking and retry. 4. Add and use anon_vma_trylock_write() to avoid blocking while in RCU read section. 5. Accommodate changes in mmu_notifier_range_init() API, switch to mmu_notifier_invalidate_range_start_nonblock() to avoid blocking while in RCU read section. 6. Open-code now removed __swp_swapcount() 7. Replace pmd_read_atomic() with pmdp_get_lockless() 8.

[RFC PATCH] kselftest/alsa: Add configuration for mt8192-asurada-spherion

by Nícolas F. R. A. Prado

Add a configuration file for the mt8192-asurada-spherion platform to validate that the card and PCMs used for speaker, headphone and microphones (internal and headset) are correctly exposed to userspace. Signed-off-by: Nícolas F. R. A. Prado <nfraprado(a)collabora.com> --- Sending this patch as RFC because I'd like to ask a question. What would be the most suitable entry to identify the card in a future-proof way? I have used the card ID here, but given that it is generated at runtime with the purpose of being unique among the cards present on the system (and I couldn't find any documentation that states it is stable), I'm not sure it is supposed to be relied on. The card ID is derived from the driver name or card longname, which are themselves stable given userspace (alsa-ucm-conf) relies on them, but those aren't exposed through sysfs so I can't check for them here. Another option would be to look for the card number 0. But in the (very unlikely) case that another soundcard would be connected to the platform and detected first during boot, it wouldn't work. Yet another option would be to look at the device's uevent file for the compatible as defined in the Devicetree, ie path "device/uevent" regex "OF_COMPATIBLE_.*=mediatek,mt8192_mt6359_rt1015p_rt5682" Though it is possible (in rare circumstances) for the compatible in the Devicetree to need to be updated to enable a driver behavior that isn't backward compatible. I realize most of these issues are very rare and probably won't ever occur, but it seems worthwhile to use the most future-proof mechanism available to identify the card to avoid unnecessary maintenance, even more so considering the example would be followed by future configurations.

[PATCH v4 0/8] add UFFDIO_POISON to simulate memory poisoning with UFFD

by Axel Rasmussen

This series adds a new userfaultfd feature, UFFDIO_POISON. See commit 4 for a detailed description of the feature. The series is based on Linus master (partial 6.5 merge window), and structured like this: - Patches 1-3 are preparation / refactoring - Patches 4-6 implement and advertise the new feature - Patches 7-8 implement a unit test for the new feature Changelog: v3 -> v4: - [Peter] Rename PTE_MARKER_ERROR and helpers to PTE_MARKER_POISONED. - [Peter] Switch from calloc to memset for initializing some state in the selftest. v2 -> v3: - Rebase onto current Linus master. - Don't overwrite existing PTE markers for non-hugetlb UFFDIO_POISON. Before, non-hugetlb would override them, but hugetlb would not. I don't think there's a use case where we *want* to override a UFFD_WP marker for example, so take the more conservative behavior for all kinds of memory. - [Peter] Drop hugetlb mfill atomic refactoring, since it isn't needed for this series (we don't touch that code directly anyway). - [Peter] Switch to re-using PTE_MARKER_SWAPIN_ERROR instead of defining new PTE_MARKER_UFFD_POISON. - [Peter] Extract start / len range overflow check into existing validate_range helper; this fixes the style issue of unnecessary braces in the UFFDIO_POISON implementation, because this code is just deleted. - [Peter] Extract file size check out into a new helper. - [Peter] Defer actually "enabling" the new feature until the last commit in the series; combine this with adding the documentation. As a consequence, move the selftest commits after this one. - [Randy] Fix typo in documentation. v1 -> v2: - [Peter] Return VM_FAULT_HWPOISON not VM_FAULT_SIGBUS, to yield the correct behavior for KVM (guest MCE). - [Peter] Rename UFFDIO_SIGBUS to UFFDIO_POISON. - [Peter] Implement hugetlbfs support for UFFDIO_POISON.
