[PATCH AUTOSEL 6.12 01/47] wifi: ath11k: Fix DMA buffer allocation to resolve SWIOTLB issues

by Sasha Levin

From: P Praneesh <quic_ppranees(a)quicinc.com> [ Upstream commit 1bcd20981834928ccc5d981aacb806bb523d8b29 ] Currently, the driver allocates cacheable DMA buffers for rings like HAL_REO_DST and HAL_WBM2SW_RELEASE. The buffers for HAL_WBM2SW_RELEASE are large (1024 KiB), exceeding the SWIOTLB slot size of 256 KiB. This leads to "swiotlb buffer is full" error messages on systems without an IOMMU that use SWIOTLB, causing driver initialization failures. The driver calls dma_map_single() with these large buffers obtained from kzalloc(), resulting in ring initialization errors on systems without an IOMMU that use SWIOTLB. To address these issues, replace the flawed buffer allocation mechanism with the appropriate DMA API. Specifically, use dma_alloc_noncoherent() for cacheable DMA buffers, ensuring proper freeing of buffers with dma_free_noncoherent(). Error log: [ 10.194343] ath11k_pci 0000:04:00.0: swiotlb buffer is full (sz:1048583 bytes), total 32768 (slots), used 2529 (slots) [ 10.194406] ath11k_pci 0000:04:00.0: failed to set up tcl_comp ring (0) :-12 [ 10.194781] ath11k_pci 0000:04:00.0: failed to init DP: -12 Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1 Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3 Reported-by: Tim Harvey <tharvey(a)gateworks.com> Closes: https://lore.kernel.org/all/20241210041133.GA17116@lst.de/ Signed-off-by: P Praneesh <quic_ppranees(a)quicinc.com> Tested-by: Tim Harvey <tharvey(a)gateworks.com> Link: https://patch.msgid.link/20250119164219.647059-2-quic_ppranees@quicinc.com Signed-off-by: Jeff Johnson <jeff.johnson(a)oss.qualcomm.com> Signed-off-by: Sasha Levin <sashal(a)kernel.org> --- drivers/net/wireless/ath/ath11k/dp.c | 35 +++++++++------------------- 1 file changed, 11 insertions(+), 24 deletions(-) diff --git a/drivers/net/wireless/ath/ath11k/dp.c b/drivers/net/wireless/ath/ath11k/dp.c index fbf666d0ecf1d..f124b7329e1ac 100644 --- a/drivers/net/wireless/ath/ath11k/dp.c +++ b/drivers/net/wireless/ath/ath11k/dp.c @@ -1,7 +1,7 @@ // SPDX-License-Identifier: BSD-3-Clause-Clear /* * Copyright (c) 2018-2019 The Linux Foundation.

[PATCH v3 0/2] Add wcslen()

by Nathan Chancellor

Hi all, A recent LLVM change [1] introduces a call to wcslen() in fs/smb/client/smb2pdu.c through UniStrcat() via alloc_path_with_tree_prefix(). Similar to the bcmp() and stpcpy() additions that happened in 5f074f3e192f and 1e1b6d63d634, add wcslen() to fix the linkage failure. [1]: https://github.com/llvm/llvm-project/commit/9694844d7e36fd5e01011ab56b64f27… --- Changes in v3: - During comment shuffle in patch 1, move to standard multi-line comment kernel style (Andy). Carry forward Andy's review. - Move nls_types.h include in string.c in patch 2 to a better place alphabetically (Andy). - Drop 'extern' from wcslen() declaration in string.h, as external linkage is the default for functions and the coding style explicitly forbids it (Andy). - Link to v2: https://lore.kernel.org/r/20250326-string-add-wcslen-for-llvm-opt-v2-0-d864… Changes in v2: - Refactor typedefs from nls.h into nls_types.h to make it safe to include in string.h, which may be included in many places throughout the kernel that may not like the other stuff nls.h brings in: https://lore.kernel.org/202503260611.MDurOUhF-lkp@intel.com/ - Drop libstub change due to the above change, as it is no longer necessary. - Move prototype shuffle of patch 2 into the patch that adds wcslen() (Andy) - Use new nls_types.h in string.{c,h} - Link to v1: https://lore.kernel.org/r/20250325-string-add-wcslen-for-llvm-opt-v1-0-b8f1… --- Nathan Chancellor (2): include: Move typedefs in nls.h to their own header lib/string.c: Add wcslen() include/linux/nls.h | 19 +------------------ include/linux/nls_types.h | 26 ++++++++++++++++++++++++++ include/linux/string.h | 2 ++ lib/string.c | 11 +++++++++++ 4 files changed, 40 insertions(+), 18 deletions(-) --- base-commit: 78ab93c78fb31c5dfe207318aa2b7bd4e41f8dba change-id: 20250324-string-add-wcslen-for-llvm-opt-705791db92c0 Best regards, -- Nathan Chancellor <nathan(a)kernel.org>

[PATCH v4 2/2] ASoC: codecs:lpass-wsa-macro: Fix logic of enabling vi channels

by srinivas.kandagatla＠linaro.org

From: Srinivas Kandagatla <srinivas.kandagatla(a)linaro.org> Existing code only configures one of WSA_MACRO_TX0 or WSA_MACRO_TX1 paths eventhough we enable both of them. Fix this bug by adding proper checks and rearranging some of the common code to able to allow setting both TX0 and TX1 paths Without this patch only one channel gets enabled in VI path instead of 2 channels.

[PATCH v4 1/2] ASoC: codecs:lpass-wsa-macro: Fix vi feedback rate

by srinivas.kandagatla＠linaro.org

From: Srinivas Kandagatla <srinivas.kandagatla(a)linaro.org> Currently the VI feedback rate is set to fixed 8K, fix this by getting the correct rate from params_rate.

[PATCH v3 2/2] ASoC: codecs:lpass-wsa-macro: Fix logic of enabling vi channels

by srinivas.kandagatla＠linaro.org

From: Srinivas Kandagatla <srinivas.kandagatla(a)linaro.org> Existing code only configures one of WSA_MACRO_TX0 or WSA_MACRO_TX1 paths eventhough we enable both of them. Fix this bug by adding proper checks and rearranging some of the common code to able to allow setting both TX0 and TX1 paths Without this patch only one channel gets enabled in VI path instead of 2 channels. End result would be 1 channel recording instead of 2.
