drm: msm: fix building without CONFIG_COMMON_CLK

2021-11-26T16:58:57+00:00

When CONFIG_COMMON_CLOCK is disabled, the 8996 specific phy code is left out, which results in a link failure: ld: drivers/gpu/drm/msm/hdmi/hdmi_phy.o:(.rodata+0x3f0): undefined reference to `msm_hdmi_phy_8996_cfg' This was only exposed after it became possible to build test the driver without the clock interfaces. Make COMMON_CLK a hard dependency for compile testing, and simplify it a little based on that.

drm/msm/dsi: Support NO_CONNECTOR bridges

2021-10-15T20:26:33+00:00

For now, since we have a mix of bridges which support this flag, which which do *not* support this flag, or work both ways, try it once with NO_CONNECTOR and then fall back to the old way if that doesn't work. Eventually we can drop the fallback path. v2: Add missing drm_connector_attach_encoder() so display actually comes up when the bridge properly handles the NO_CONNECTOR flag Signed-off-by: Rob Clark Reviewed-by: Laurent Pinchart Reviewed-by: Dmitry Baryshkov Link: https://lore.kernel.org/r/20210920225801.227211-2-robdclark@gmail.com Signed-off-by: Dmitry Baryshkov Signed-off-by: Rob Clark

qcom_scm: hide Kconfig symbol

2021-10-07T14:51:57+00:00

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 Acked-by: Alex Elder Signed-off-by: Arnd Bergmann

drm/msm: allow compile_test on !ARM

2021-09-28T06:42:00+00:00

MSM is one of the few drivers which won't even compile test on !ARM platforms. Looking into this a bit more it turned out that there is actually not that much missing to at least let the driver compile on x86 as well. So this patch replaces the use of phys_to_page() with the open coded version and provides a dummy for of_drm_find_bridge().

drm/msm: Conversion to drm scheduler

2021-07-28T16:19:00+00:00

For existing adrenos, there is one or more ringbuffer, depending on whether preemption is supported. When preemption is supported, each ringbuffer has it's own priority. A submitqueue (which maps to a gl context or vk queue in userspace) is mapped to a specific ring- buffer at creation time, based on the submitqueue's priority. Each ringbuffer has it's own drm_gpu_scheduler. Each submitqueue maps to a drm_sched_entity. And each submit maps to a drm_sched_job.
