2022-04-25drm/display: Introduce a DRM display-helper moduleThomas Zimmermann1-1/+2
Replace the DP-helper module with a display-helper module. The support for DisplayPort becomes an internal option that drivers have to select. Update all related Kconfig and Makefile rules. Besides the existing code for DisplayPort, the new module will contain helpers for other video-output standards, such as HDMI. Drivers will have to select their required video-output helpers. Linking all display-related code into a single module avoids the proliferation of small kernel modules. The module parameters drm_dp_cec_unregister_delay, dp_aux_i2c_speed_khz, and dp_aux_i2c_transfer_size are moving from the drm_dp_helper namespace to drm_display_helper. v2: * mention module parameters in commit message (Javier) * distiguish between display module and DP support in Kconfig * update Makefile rules for DP helpers * move Kconfig rules into separate file under display/ Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Lyude Paul <lyude@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220421073108.19226-4-tzimmermann@suse.de

2022-02-18drm/msm: drop register logging supportDmitry Baryshkov1-9/+0
Register logging was used during early stages of msm driver development to compare upstream and downstream register traces. However the tool was never updated to work with mdp5 hardware. Later it was dropped completely when Rob imported freedreno tools into mesa. All this makes DRM_MSM_REGISTER_LOGGING irrelevant now, so it can be dropped.

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.

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.

Try to get the interconnect path for the GPU and vote for the maximum bandwidth to support all frequencies. This is needed for performance. Later we will want to scale the bandwidth based on the frequency to also optimize for power but that will require some device tree infrastructure that does not yet exist. v6: use icc_set_bw() instead of icc_set() v5: Remove hardcoded interconnect name and just use the default v4: Don't use a port string at all to skip the need for names in the DT v3: Use macros and change port string per Georgi Djakov Signed-off-by: Jordan Crouse <jcrouse@codeaurora.org> Acked-by: Rob Clark <robdclark@gmail.com> Reviewed-by: Evan Green <evgreen@chromium.org> Signed-off-by: Georgi Djakov <georgi.djakov@linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Capture the GPU state on a GPU hang and store it for later playback via the devcoredump facility.

The existing crash state can be cleared after capturing it and then a new one will be captured on the next hang.

This flags cause cmdstream to be executed from the ringbuffer (RB) instead of IB1. Normally not something you'd ever want to do, but it is super useful for firmware debugging. Hidden behind CAP_SYS_RAWIO and a default=n kconfig option which depends on EXPERT (and has a suitably scary warning), to prevent it from being used on accident.

2017-08-01drm/msm: gpu: call qcom_mdt interfaces only for ARCH_QCOMArnd Bergmann1-1/+1
When compile-testing for something other than ARCH_QCOM, we run into a link error: drivers/gpu/drm/msm/adreno/a5xx_gpu.o: In function `a5xx_hw_init': a5xx_gpu.c:(.text.a5xx_hw_init+0x600): undefined reference to `qcom_mdt_get_size' a5xx_gpu.c:(.text.a5xx_hw_init+0x93c): undefined reference to `qcom_mdt_load' There is already an #ifdef that tries to check for CONFIG_QCOM_MDT_LOADER, but that symbol is only meaningful when building for ARCH_QCOM. This adds a compile-time check for ARCH_QCOM, and clarifies the Kconfig select statement so we don't even try it for other targets. The check for CONFIG_QCOM_MDT_LOADER can then go away, which also improves compile-time coverage and makes the code a little nicer to read.

2017-06-16drm/msm: gpu: Enable zap shader for A5XXJordan Crouse1-0/+1
The A5XX GPU powers on in "secure" mode. In secure mode the GPU can only render to buffers that are marked as secure and inaccessible to the kernel and user through a series of hardware protections. In practice secure mode is used to draw things like a UI on a secure video frame. In order to switch out of secure mode the GPU executes a special shader that clears out the GMEM and other sensitve registers and then writes a register. Because the kernel can't be trusted the shader binary is signed and verified and programmed by the secure world. To do this we need to read the MDT header and the segments from the firmware location and put them in memory and present them for approval. For targets without secure support there is an out: if the secure world doesn't support secure then there are no hardware protections and we can freely write the SECVID_TRUST register from the CPU. We don't have 100% confidence that we can query the secure capabilities at run time but we have enough calls that need to go right to give us some confidence that we're at least doing something useful. Of course if we guess wrong you trigger a permissions violation which usually ends up in a system crash but thats a problem that shows up immediately.

2017-02-06drm/msm/dsi: Add PHY/PLL for 8x96Archit Taneja1-0/+7
Extend the DSI PHY/PLL drivers to support the DSI 14nm PHY/PLL found on 8x96. These are picked up from the downstream driver. The PHY part is similar to the other DSI PHYs. The PLL driver requires some trickery so that one DSI PLL can drive both the DSIs (i.e, dual DSI mode). In the case of dual DSI mode. One DSI instance becomes the clock master, and other the clock slave. The master PLL's output (Byte and Pixel clock) is fed to both the DSI hosts/PHYs. When the DSIs are configured in dual DSI mode, the PHY driver communicates to the PLL driver using msm_dsi_pll_set_usecase() which instance is the master and which one is the slave. When setting rate, the master PLL also configures some of the slave PLL/PHY registers which need to be identical to the master's for correct dual DSI behaviour. There are 2 PLL post dividers that should have ideally been modelled as generic clk_divider clocks, but require some customization for dual DSI. In particular, when the master PLL's post-diviers are set, the slave PLL's post-dividers need to be set too. The clk_ops for these use clk_divider's helper ops and flags internally to prevent redundant code.
