2018-12-11drm/msm: add headless gpu device for imx5Jonathan Marek
This patch allows using drm/msm without qcom display hardware. It adds a amd,imageon compatible, which is used instead of qcom,adreno, but does not require a top level msm node. Signed-off-by: Jonathan Marek <jonathan@marek.ca> Signed-off-by: Rob Clark <robdclark@gmail.com>
2018-07-30drm/msm/gpu: Capture the GPU state on a GPU hangJordan Crouse
Capture the GPU state on a GPU hang and store it for later playback via the devcoredump facility. Only one crash state is stored at a time on the assumption that the first hang is usually the most interesting. The existing crash state can be cleared after capturing it and then a new one will be captured on the next hang.

2018-02-20drm/msm: add sudo flag to submit ioctlRob Clark
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 Bergmann
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 Crouse
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 Taneja
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.

Many DRM drivers only work with an MMU, and after the patch to enable core DRM support without MMU, we already had one fixup for many of them.

2014-09-10drm/msm/mdp4: add LVDS panel supportRob Clark
LVDS panel support uses the LCDC (parallel) encoder. Unlike with HDMI, there is not a separate LVDS block, so no need to split things into a bridge+connector. Nor is there is anything re-used with mdp5. Note that there can be some regulators shared between HDMI and LVDS (in particular, on apq8064, ext_3v3p), so we should not use the _exclusive() variants of devm_regulator_get(). The drm_panel framework is used for panel-specific driver. Signed-off-by: Rob Clark <robdclark@gmail.com>
2014-08-04drm/msm: use upstream iommuRob Clark
Downstream kernel IOMMU had a non-standard way of dealing with multiple devices and multiple ports/contexts. We don't need that on upstream kernel, so rip out the crazy. Note that we have to move the pinning of the ringbuffer to after the IOMMU is attached. No idea how that managed to work properly on the downstream kernel. For now, I am leaving the IOMMU port name stuff in place, to simplify things for folks trying to backport latest drm/msm to device kernels. Once we no longer have to care about pre-DT kernels, we can drop this and instead backport upstream IOMMU driver. Signed-off-by: Rob Clark <robdclark@gmail.com>

2013-10-11drm: Add separate Kconfig option for fbdev helpersDaniel Vetter
For drivers which might want to disable fbdev legacy support. Select the new option in all drivers for now, so this shouldn't result in any change. Drivers need some work anyway to make fbdev support optional (if they have it implemented, that is), so the recommended way to expose this is by adding per-driver options. At least as long as most drivers don't support disabling the fbdev support. v2: Update for new drm drivers msm and rcar-du. Note that Rob's msm driver can already take advantage of this, which allows us to build msm without any fbdev depencies in the kernel! v3: Move the MODULE_* stuff from the fbdev helper file to drm_crtc_helper.c.

2013-08-24drm/msm: basic KMS driver for snapdragonRob Clark
The snapdragon chips have multiple different display controllers, depending on which chip variant/version. (As far as I can tell, current devices have either MDP3 or MDP4, and upcoming devices have MDSS.) And then external to the display controller are HDMI, DSI, etc. blocks which may be shared across devices which have different display controller blocks. To more easily add support for different display controller blocks, the display controller specific bits are split out into a "kms" module, which provides the kms plane/crtc/encoder objects. The external HDMI, DSI, etc. blocks are part encoder, and part connector currently. But I think I will pull in the drm_bridge patches from chromeos tree, and split them into a bridge+connector, with the registers that need to be set in modeset handled by the bridge. This would remove the 'msm_connector' base class. But some things need to be double checked to make sure I could get the correct ON/OFF sequencing.. This patch adds support for mdp4 crtc (including hw cursor), dtv encoder (part of MDP4 block), and hdmi. Signed-off-by: Rob Clark <robdclark@gmail.com>
