2024-09-05arm64: stacktrace: fix the usage of ftrace_graph_ret_addr()Puranjay Mohan1-1/+3
ftrace_graph_ret_addr() takes an 'idx' integer pointer that is used to optimize the stack unwinding process. arm64 currently passes `NULL` for this parameter which stops it from utilizing these optimizations. Further, the current code for ftrace_graph_ret_addr() will just return the passed in return address if it is NULL which will break this usage. Pass a valid integer pointer to ftrace_graph_ret_addr() similar to x86_64's stack unwinder.

2024-09-05xsk: Bump xsk_queue::queue_empty_descs in xp_can_alloc()Maciej Fijalkowski2-6/+9
We have STAT_FILL_EMPTY test case in xskxceiver that tries to process traffic with fill queue being empty which currently fails for zero copy ice driver after it started to use xsk_buff_can_alloc() API. That is because xsk_queue::queue_empty_descs is currently only increased from alloc APIs and right now if driver sees that xsk_buff_pool will be unable to provide the requested count of buffers, it bails out early, skipping calls to xsk_buff_alloc{_batch}(). Mentioned statistic should be handled in xsk_buff_can_alloc() from the very beginning, so let's add this logic now. Do it by open coding xskq_cons_has_entries() and bumping queue_empty_descs in the middle when fill queue currently has no entries.

2024-09-05of: address: Report error on resource bounds overflowThomas Weißschuh1-0/+5
The members "start" and "end" of struct resource are of type "resource_size_t" which can be 32bit wide. Values read from OF however are always 64bit wide. Avoid silently truncating the value and instead return an error value. This can happen on real systems when the DT was created for a PAE-enabled kernel and a non-PAE kernel is actually running. For example with an arm defconfig and "qemu-system-arm -M virt".

2024-09-05s390/sha3: Fix SHA3 selftests failuresIngo Franzki3-0/+7
Since commit "s390/sha3: Support sha3 performance enhancements" the selftests of the sha3_256_s390 and sha3_512_s390 kernel digests sometimes fail with: alg: shash: sha3-256-s390 test failed (wrong result) on test vector 3, cfg="import/export" alg: self-tests for sha3-256 using sha3-256-s390 failed (rc=-22) or with alg: ahash: sha3-256-s390 test failed (wrong result) on test vector 3, cfg="digest misaligned splits crossing pages" alg: self-tests for sha3-256 using sha3-256-s390 failed (rc=-22) The first failure is because the newly introduced context field 'first_message_part' is not copied during export and import operations. Because of that the value of 'first_message_part' is more or less random after an import into a newly allocated context and may or may not fit to the state of the imported SHA3 operation, causing an invalid hash when it does not fit. Save the 'first_message_part' field in the currently unused field 'partial' of struct sha3_state, even though the meaning of 'partial' is not exactly the same as 'first_message_part'. For the caller the returned state blob is opaque and it must only be ensured that the state can be imported later on by the module that exported it. The second failure is when on entry of s390_sha_update() the flag 'first_message_part' is on, and kimd is called in the first 'if (index)' block as well as in the second 'if (len >= bsize)' block. In this case, the 'first_message_part' is turned off after the first kimd, but the function code incorrectly retains the NIP flag. Reset the NIP flag after the first kimd unconditionally besides turning 'first_message_part' off.

2024-09-05powerpc/mm/64s: Restrict THP to Radix or HPT w/64K pagesMichael Ellerman1-0/+1
Transparent hugepages (THP) are not supported when using the Hash Page Table (HPT) MMU with 4K pages. Currently a HPT-only 4K kernel still allows THP to be enabled, which is misleading. Add restrictions to the PPC_THP symbol so that if the kernel is configured with 4K pages and only the HPT MMU (no Radix), then THP is disabled. Note that it's still possible to build a combined Radix/HPT kernel with 4K pages, which does allow THP to be enabled at build time. As such the HPT code still needs to provide some THP related symbols, to allow the build to succeed, but those code paths are never run. See the stubs in arch/powerpc/include/asm/book3s/64/hash-4k.h.

2024-09-05powerpc/mm/64s: Move THP reqs into a separate symbolMichael Ellerman1-3/+7
Move the Kconfig symbols related to transparent hugepages (THP) under a separate config symbol, separate from CONFIG_PPC_BOOK3S_64. The new symbol is automatically enabled if CONFIG_PPC_BOOK3S_64 is enabled, so there is no behaviour change, except for the existence of the new PPC_THP symbol.

2024-09-05powerpc: Replace kretprobe code with rethook on powerpcAbhishek Dubey6-67/+81
This is an adaptation of commit f3a112c0c40d ("x86,rethook,kprobes: Replace kretprobe with rethook on x86") to powerpc. Rethook follows the existing kretprobe implementation, but separates it from kprobes so that it can be used by fprobe (ftrace-based function entry/exit probes). As such, this patch also enables fprobe to work on powerpc. The only other change compared to the existing kretprobe implementation is doing the return address fixup in arch_rethook_fixup_return(). Reference to other archs: commit b57c2f124098 ("riscv: add riscv rethook implementation") commit 7b0a096436c2 ("LoongArch: Replace kretprobe with rethook") Note: ===== In future, rethook will be only for kretprobe, and kretprobe will be replaced by fprobe. https://lore.kernel.org/all/172000134410.63468.13742222887213469474.stgit@devnote2/ We will adapt the above implementation for powerpc once its upstream. Until then, we can have this implementation of rethook to serve current kretprobe usecases.

The commit 783bf5d09f86 ("spi: spi-fsl-lpspi: limit PRESCALE bit in TCR register") doesn't implement the prescaler maximum as intended. The maximum allowed value for i.MX93 should be 1 and for i.MX7ULP it should be 7. So this needs also a adjustment of the comparison in the scldiv calculation.

2024-09-05ASoC: atmel: mchp-i2s-mcc: Improve maxburst calculation for better performanceCodrin Ciubotariu1-5/+33
The period size represents the size of the DMA descriptor. To ensure all DMA descriptors start from a well-aligned address, the period size must be divided by (sample size * maxburst), not just by maxburst. This adjustment allows for computing a higher maxburst value, thereby increasing the performance of the DMA transfer. Previously, snd_pcm_lib_period_bytes() returned 0 because the runtime HW parameters are computed after the hw_params() callbacks are used. To address this, we now use params_*() functions to compute the period size accurately. This change optimizes the DMA transfer performance by ensuring proper alignment and efficient use of maxburst values. [[email protected]: Reword commit message and commit title. Add macros with values for maximum DMA chunk size allowed.
