[PATCH v2] drm/msm/dp: only signal audio when disconnected detected at dp_pm_resume
by Kuogee Hsieh 30 Sep '21

30 Sep '21

Currently there is audio not working problem after system resume from suspend if hdmi monitor stay plugged in at DUT. However this problem does not happen at normal operation but at a particular test case. The root cause is DP driver signal audio with connected state at resume which trigger audio trying to setup audio data path through DP main link but failed due to display port is not setup and enabled by upper layer framework yet. This patch only have DP driver signal audio only when DP is in disconnected state so that audio option shows correct state after system resume. DP driver will not signal audio with connected state until display enabled executed by upper layer framework where display port is setup completed and main link is running.

[PATCH] [RFC] qcom_scm: hide Kconfig symbol
by Arnd Bergmann 29 Sep '21

29 Sep '21

From: Arnd Bergmann <arnd(a)arndb.de> Now that SCM can be a loadable module, we have to add another dependency to avoid link failures when ipa or adreno-gpu are built-in: aarch64-linux-ld: drivers/net/ipa/ipa_main.o: in function `ipa_probe': ipa_main.c:(.text+0xfc4): undefined reference to `qcom_scm_is_available' ld.lld: error: undefined symbol: qcom_scm_is_available >>> referenced by adreno_gpu.c >>> gpu/drm/msm/adreno/adreno_gpu.o:(adreno_zap_shader_load) in archive drivers/built-in.a This can happen when CONFIG_ARCH_QCOM is disabled and we don't select QCOM_MDT_LOADER, but some other module selects QCOM_SCM. Ideally we'd use a similar dependency here to what we have for QCOM_RPROC_COMMON, but that causes dependency loops from other things selecting QCOM_SCM. This appears to be an endless problem, so try something different this time: - CONFIG_QCOM_SCM becomes a hidden symbol that nothing 'depends on' but that is simply selected by all of its users - All the stubs in include/linux/qcom_scm.h can go away - arm-smccc.h needs to provide a stub for __arm_smccc_smc() to allow compile-testing QCOM_SCM on all architectures. - To avoid a circular dependency chain involving RESET_CONTROLLER and PINCTRL_SUNXI, change the 'depends on RESET_CONTROLLER' in the latter one to 'select'. The last bit is rather annoying, as drivers should generally never 'select' another subsystem, and about half the users of the reset controller interface do this anyway. Nevertheless, this version seems to pass all my randconfig tests and is more robust than any of the prior versions. Comments?

[PATCH 0/3] Rename IS_ACTIVE() and move to kconfig.h
by Lucas De Marchi 29 Sep '21

29 Sep '21

As we try to reduce our i915-only helpers, let's try to improve IS_ACTIVE() logic and move to kconfig.h. I'm not 100% happy with the name, but it's the best I could come up with, hopefully a little better than trying to add IS_ACTIVE() to be used broadly.

[PATCH v2] drm/i915/bdb: Fix version check
by Lukasz Majczak 29 Sep '21

29 Sep '21

With patch "drm/i915/vbt: Fix backlight parsing for VBT 234+" the size of bdb_lfp_backlight_data structure has been increased, causing if-statement in the parse_lfp_backlight function that comapres this structure size to the one retrieved from BDB, always to fail for older revisions. This patch calculates expected size of the structure for a given BDB version and compares it with the value gathered from BDB.

[PATCH 2/2] [v2] qcom_scm: hide Kconfig symbol
by Arnd Bergmann 29 Sep '21

29 Sep '21

From: Arnd Bergmann <arnd(a)arndb.de> Now that SCM can be a loadable module, we have to add another dependency to avoid link failures when ipa or adreno-gpu are built-in: aarch64-linux-ld: drivers/net/ipa/ipa_main.o: in function `ipa_probe': ipa_main.c:(.text+0xfc4): undefined reference to `qcom_scm_is_available' ld.lld: error: undefined symbol: qcom_scm_is_available >>> referenced by adreno_gpu.c >>> gpu/drm/msm/adreno/adreno_gpu.o:(adreno_zap_shader_load) in archive drivers/built-in.a This can happen when CONFIG_ARCH_QCOM is disabled and we don't select QCOM_MDT_LOADER, but some other module selects QCOM_SCM. Ideally we'd use a similar dependency here to what we have for QCOM_RPROC_COMMON, but that causes dependency loops from other things selecting QCOM_SCM. This appears to be an endless problem, so try something different this time: - CONFIG_QCOM_SCM becomes a hidden symbol that nothing 'depends on' but that is simply selected by all of its users - All the stubs in include/linux/qcom_scm.h can go away - arm-smccc.h needs to provide a stub for __arm_smccc_smc() to allow compile-testing QCOM_SCM on all architectures. - To avoid a circular dependency chain involving RESET_CONTROLLER and PINCTRL_SUNXI, drop the 'select RESET_CONTROLLER' statement. According to my testing this still builds fine, and the QCOM platform selects this symbol already. Acked-by: Kalle Valo <kvalo(a)codeaurora.org> Signed-off-by: Arnd Bergmann <arnd(a)arndb.de> --- Changes in v2: - drop the 'select RESET_CONTROLLER' line, rather than adding more of the same --- drivers/firmware/Kconfig | 5 +- drivers/gpu/drm/msm/Kconfig | 4 +- drivers/iommu/Kconfig | 2 +- drivers/media/platform/Kconfig | 2 +- drivers/mmc/host/Kconfig | 2 +- drivers/net/ipa/Kconfig | 1 + drivers/net/wireless/ath/ath10k/Kconfig | 2 +- drivers/pinctrl/qcom/Kconfig | 3 +- include/linux/arm-smccc.h | 10 ++++ include/linux/qcom_scm.h | 71 ------------------------- 10 files changed, 20 insertions(+), 82 deletions(-) diff --git a/drivers/firmware/Kconfig b/drivers/firmware/Kconfig index 220a58cf0a44..cda7d7162cbb 100644 --- a/drivers/firmware/Kconfig +++ b/drivers/firmware/Kconfig @@ -203,10 +203,7 @@ config INTEL_STRATIX10_RSU Say Y here if you want Intel RSU support. config QCOM_SCM - tristate "Qcom SCM driver" - depends on ARM || ARM64 - depends on HAVE_ARM_SMCCC - select RESET_CONTROLLER + tristate config QCOM_SCM_DOWNLOAD_MODE_DEFAULT bool "Qualcomm download mode enabled by default" diff --git a/drivers/gpu/drm/msm/Kconfig b/drivers/gpu/drm/msm/Kconfig index e9c6af78b1d7..3ddf739a6f9b 100644 --- a/drivers/gpu/drm/msm/Kconfig +++ b/drivers/gpu/drm/msm/Kconfig @@ -17,7 +17,7 @@ config DRM_MSM select DRM_SCHED select SHMEM select TMPFS - select QCOM_SCM if ARCH_QCOM + select QCOM_SCM select WANT_DEV_COREDUMP select SND_SOC_HDMI_CODEC if SND_SOC select SYNC_FILE @@ -55,7 +55,7 @@ config DRM_MSM_GPU_SUDO config DRM_MSM_HDMI_HDCP bool "Enable HDMI HDCP support in MSM DRM driver" - depends on DRM_MSM && QCOM_SCM + depends on DRM_MSM default y help Choose this option to enable HDCP state machine diff --git a/drivers/iommu/Kconfig b/drivers/iommu/Kconfig index 124c41adeca1..989c83acbfee 100644 --- a/drivers/iommu/Kconfig +++ b/drivers/iommu/Kconfig @@ -308,7 +308,7 @@ config APPLE_DART config ARM_SMMU tristate "ARM Ltd.
