We don't need to run the validation of the XML files if we are just compiling the kernel. Skip the validation unless the user enables corresponding Kconfig option.

2024-05-02Revert "drm: Switch DRM_DISPLAY_HELPER to depends on"Geert Uytterhoeven1-2/+2
This reverts commit e075e496f516bf92bc0cbaf94d64e8d4a6b58321, as helper code should always be selected by the driver that needs it, for the convenience of the final user configuring a kernel. The user who configures a kernel should not need to know which helpers are needed for the driver he is interested in. Making a driver depend on helper code means that the user needs to know which helpers to enable first, which is very user-unfriendly.

2024-03-28drm: Switch DRM_DISPLAY_DP_HELPER to depends onMaxime Ripard1-1/+1
Most of our helpers have relied on being selected so far through Kconfig, but that creates issues when we have multiple layers of helpers with some depending on others. Indeed, select doesn't select a dependency's dependencies, and thus isn't super intuitive. Depends on however doesn't have that limitation, so we can just switch all the drivers that were selecting DRM_DISPLAY_DP_HELPER to depend on it.

2023-06-01drm/msm: Use regular fbdev I/O helpersThomas Zimmermann1-0/+1
Use the regular fbdev helpers for framebuffer I/O instead of DRM's helpers. Msm does not use damage handling, so DRM's fbdev helpers are mere wrappers around the fbdev code. By using fbdev helpers directly within each DRM fbdev emulation, we can eventually remove DRM's wrapper functions entirely. Msm's fbdev emulation has been incomplete as it didn't implement damage handling. Partilly fix this by implementing damage handling for write and draw operation. It is still missing for mmaped pages. v4: * use initializer macros for struct fb_ops * partially support damage handling v2: * use FB_SYS_HELPERS option Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Acked-by: Sam Ravnborg <sam@ravnborg.org> Cc: Rob Clark <robdclark@gmail.com> Cc: Abhinav Kumar <quic_abhinavk@quicinc.com> Cc: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Cc: Sean Paul <sean@poorly.run> Link: https://patchwork.freedesktop.org/patch/msgid/20230530151228.22979-12-tzimmermann@suse.de

Move DisplayPort functions into a separate module to reduce the size of the KMS helpers. Select DRM_DP_HELPER for all users of the code. To avoid naming conflicts, rename drm_dp_helper.c to drm_dp.c This change can help to reduce the size of the kernel binary. Some numbers from a x86-64 test build: Before: drm_kms_helper.ko: 447480 bytes After: drm_dp_helper.ko: 216632 bytes drm_kms_helper.ko: 239424 bytes For early-boot graphics, generic DRM drivers, such as simpledrm, require DRM KMS helpers to be built into the kernel. Generic helper functions for DisplayPort take up a significant portion of DRM KMS helper library.

2021-10-07qcom_scm: hide Kconfig symbolArnd Bergmann1-2/+2
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.

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().

2021-07-28drm/msm: Conversion to drm schedulerRob Clark1-0/+1
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.
