[PATCH] ASoC: amd: vangogh: Use non-legacy DAI naming for cs35l41
by Cristian Ciocaltea 22 Jul '22

22 Jul '22

Unlike most CODEC drivers, the CS35L41 driver did not have the non_legacy_dai_naming set, meaning the corresponding DAI has been traditionally registered using the legacy naming: spi-VLV1776:0x The recent migration to the new legacy DAI naming style has implicitly corrected that behavior and DAI gets now registered via the non-legacy naming, i.e. cs35l41-pcm. The problem is the acp5x platform driver is now broken as it continues to refer to the above mentioned codec using the legacy DAI naming in function acp5x_cs35l41_hw_params() and, therefore, the related setup is not being executed anymore. Let's fix that by replacing the obsolete DAI name with the correct one.

[PATCH] ASoC: cs35l41: Set the new legacy DAI naming flag
by Cristian Ciocaltea 22 Jul '22

22 Jul '22

Unlike most CODEC drivers, the CS35L41 driver did not have the non_legacy_dai_naming set, meaning it uses the legacy naming. The recent migration to the new legacy DAI naming style has broken driver functionality because it is now expected to set the new legacy DAI naming flag in order to instruct the core subsystem to use the legacy name format on DAI registration. Let's fix this by setting the legacy_dai_naming flag accordingly.

[PATCH] ASoC: Intel: avs: Mark avs_path_module_type_create() as noinline
by Nathan Chancellor 21 Jul '22

21 Jul '22

When building ARCH=arm64 allmodconfig with clang, there is a warning about high stack usage in avs_path_create(), which breaks the build due to CONFIG_WERROR=y: sound/soc/intel/avs/path.c:815:18: error: stack frame size (2176) exceeds limit (2048) in 'avs_path_create' [-Werror,-Wframe-larger-than] struct avs_path *avs_path_create(struct avs_dev *adev, u32 dma_id, ^ 1 error generated. This warning is also visible with allmodconfig on other architectures. The minimum set of configs that triggers this on top of ARCH=arm64 allnoconfig: CONFIG_COMPILE_TEST=y CONFIG_FORTIFY_SOURCE=y CONFIG_KASAN=y CONFIG_PCI=y CONFIG_SOUND=y CONFIG_SND=y CONFIG_SND_SOC=y CONFIG_SND_SOC_INTEL_AVS=y When CONFIG_FORTIFY_SOURCE is enabled, memcmp() (called from guid_equal()) becomes a wrapper to do compile time checking, which interacts poorly with inlining plus CONFIG_KASAN=y. With ARCH=arm64 allmodconfig + CONFIG_KASAN=n + CONFIG_FRAME_WARN=128, the stack usage is much better: sound/soc/intel/avs/path.c:815:18: warning: stack frame size (624) exceeds limit (128) in 'avs_path_create' [-Wframe-larger-than] struct avs_path *avs_path_create(struct avs_dev *adev, u32 dma_id, ^ sound/soc/intel/avs/path.c:873:5: warning: stack frame size (144) exceeds limit (128) in 'avs_path_bind' [-Wframe-larger-than] int avs_path_bind(struct avs_path *path) ^ 2 warnings generated. To avoid this warning, mark avs_path_module_type_create() as noinline_for_stack, which redistributes the stack usage across multiple functions, regardless of CONFIG_KASAN. With ARCH=arm64 allmodconfig + CONFIG_FRAME_WARN=128, the warnings show: avs_path_create(): 192 avs_path_bind(): 272 avs_path_module_type_create(): 416 avs_mux_create(): 160 avs_updown_mix_create(): 160 avs_aec_create(): 176 avs_asrc_create(): 144 With ARCH=arm64 allmodconfig + CONFIG_FRAME_WARN=128 + CONFIG_KASAN=n, the warnings show: avs_path_create(): 192 avs_path_bind(): 144 avs_path_module_type_create(): 416 avs_mux_create(): 176 avs_updown_mix_create(): 176 avs_src_create(): 144 avs_aec_create(): 192 avs_asrc_create(): 144 avs_wov_create(): 144 Link: https://github.com/ClangBuiltLinux/linux/issues/1642 Signed-off-by: Nathan Chancellor <nathan(a)kernel.org> --- sound/soc/intel/avs/path.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/sound/soc/intel/avs/path.c b/sound/soc/intel/avs/path.c index 3d46dd5e5bc4..ec2aa0001f91 100644 --- a/sound/soc/intel/avs/path.c +++ b/sound/soc/intel/avs/path.c @@ -449,7 +449,8 @@ static int avs_modext_create(struct avs_dev *adev, struct avs_path_module *mod) return ret; } -static int avs_path_module_type_create(struct avs_dev *adev, struct avs_path_module *mod) +static noinline_for_stack int avs_path_module_type_create(struct avs_dev *adev, + struct avs_path_module *mod) { const guid_t *type = &mod->template->cfg_ext->type; base-commit: ff6992735ade75aae3e35d16b17da1008d753d28 -- 2.37.1

[PATCH v5 2/4] PCI: Move isa_dma_bridge_buggy out of dma.h
by Stafford Horne 21 Jul '22

21 Jul '22

During recent PCI cleanups we noticed that the isa_dma_bridge_buggy symbol supported by all architectures is actually only used for x86_32. This patch moves the symbol out of all architectures limiting usage to only x86_32. This is possible because only x86_32 platforms or quirks existing in PCI devices supported on x86_32 ever set this. A new global header linux/isa-dma.h is added to provide a common place to maintain the definition.
