2021-04-02drm/msm: Fix removal of valid error case when checking speed_binJohn Stultz1-1/+7
Commit 7bf168c8fe8c ("drm/msm: Fix speed-bin support not to access outside valid memory"), reworked the nvmem reading of "speed_bin", but in doing so dropped handling of the -ENOENT case which was previously documented as "fine". That change resulted in the db845c board display to fail to start, with the following error: adreno 5000000.gpu: [drm:a6xx_gpu_init] *ERROR* failed to read speed-bin (-2). Some OPPs may not be supported by hardware Thus, this patch simply re-adds the ENOENT handling so the lack of the speed_bin entry isn't fatal for display, and gets things working on db845c.

2021-04-02drm/msm: Set drvdata to NULL when msm_drm_init() failsStephen Boyd1-0/+1
We should set the platform device's driver data to NULL here so that code doesn't assume the struct drm_device pointer is valid when it could have been destroyed. The lifetime of this pointer is managed by a kref but when msm_drm_init() fails we call drm_dev_put() on the pointer which will free the pointer's memory. This driver uses the component model, so there's sort of two "probes" in this file, one for the platform device i.e. msm_pdev_probe() and one for the component i.e. msm_drm_bind(). The msm_drm_bind() code is using the platform device's driver data to store struct drm_device so the two functions are intertwined. This relationship becomes a problem for msm_pdev_shutdown() when it tests the NULL-ness of the pointer to see if it should call drm_atomic_helper_shutdown(). The NULL test is a proxy check for if the pointer has been freed by kref_put(). If the drm_device has been destroyed, then we shouldn't call the shutdown helper, and we know that is the case if msm_drm_init() failed, therefore set the driver data to NULL so that this pointer liveness is tracked properly.

Amdgpu driver uses 4-byte data type as DQM fence memory, and transmits GPU address of fence memory to microcode through query status PM4 message. However, query status PM4 message definition and microcode processing are all processed according to 8 bytes. Fence memory only allocates 4 bytes of memory, but microcode does write 8 bytes of memory, so there is a memory corruption.

2021-03-30drm/tegra: sor: Grab runtime PM reference across resetThierry Reding1-0/+7
The SOR resets are exclusively shared with the SOR power domain. This means that exclusive access can only be granted temporarily and in order for that to work, a rigorous sequence must be observed. To ensure that a single consumer gets exclusive access to a reset, each consumer must implement a rigorous protocol using the reset_control_acquire() and reset_control_release() functions. However, these functions alone don't provide any guarantees at the system level. Drivers need to ensure that the only a single consumer has access to the reset at the same time. In order for the SOR to be able to exclusively access its reset, it must therefore ensure that the SOR power domain is not powered off by holding on to a runtime PM reference to that power domain across the reset assert/deassert operation. This used to work fine by accident, but was revealed when recently more devices started to rely on the SOR power domain.

2021-03-30drm/tegra: dc: Don't set PLL clock to 0HzDmitry Osipenko1-5/+5
RGB output doesn't allow to change parent clock rate of the display and PCLK rate is set to 0Hz in this case. The tegra_dc_commit_state() shall not set the display clock to 0Hz since this change propagates to the parent clock. The DISP clock is defined as a NODIV clock by the tegra-clk driver and all NODIV clocks use the CLK_SET_RATE_PARENT flag. This bug stayed unnoticed because by default PLLP is used as the parent clock for the display controller and PLLP silently skips the erroneous 0Hz rate changes because it always has active child clocks that don't permit rate changes. The PLLP isn't acceptable for some devices that we want to upstream (like Samsung Galaxy Tab and ASUS TF700T) due to a display panel clock rate requirements that can't be fulfilled by using PLLP and then the bug pops up in this case since parent clock is set to 0Hz, killing the display output. Don't touch DC clock if pclk=0 in order to fix the problem. Signed-off-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com>

2021-03-25drm/imx: imx-ldb: fix out of bounds array access warningArnd Bergmann1-0/+10
When CONFIG_OF is disabled, building with 'make W=1' produces warnings about out of bounds array access: drivers/gpu/drm/imx/imx-ldb.c: In function 'imx_ldb_set_clock.constprop': drivers/gpu/drm/imx/imx-ldb.c:186:8: error: array subscript -22 is below array bounds of 'struct clk *[4]' [-Werror=array-bounds] Add an error check before the index is used, which helps with the warning, as well as any possible other error condition that may be triggered at runtime. The warning could be fixed by adding a Kconfig depedency on CONFIG_OF, but Liu Ying points out that the driver may hit the out-of-bounds problem at runtime anyway.

2021-03-25drm/nouveau/kms/nve4-nv108: Limit cursors to 128x128Lyude Paul1-1/+12
While Kepler does technically support 256x256 cursors, it turns out that Kepler actually has some additional requirements for scanout surfaces that we're not enforcing correctly, which aren't present on Maxwell and later. Cursor surfaces must always use small pages (4K), and overlay surfaces must always use large pages (128K). Fixing this correctly though will take a bit more work: as we'll need to add some code in prepare_fb() to move cursor FBs in large pages to small pages, and vice-versa for overlay FBs. So until we have the time to do that, just limit cursor surfaces to 128x128 - a size small enough to always default to small pages. This means small ovlys are still broken on Kepler, but it is extremely unlikely anyone cares about those anyway :).

2021-03-24drm/i915: Fix the GT fence revocation runtime PM logicImre Deak3-6/+41
To optimize some task deferring it until runtime resume unless someone holds a runtime PM reference (because in this case the task can be done w/o the overhead of runtime resume), we have to use the runtime PM get-if-active logic: If the runtime PM usage count is 0 (and so get-if-in-use would return false) the runtime suspend handler is not necessarily called yet (it could be just pending), so the device is not necessarily powered down, and so the runtime resume handler is not guaranteed to be called. The fence revocation depends on the above deferral, so add a get-if-active helper and use it during fence revocation. v2: - Add code comment explaining the fence reg programming deferral logic to i915_vma_revoke_fence(). (Chris) - Add Cc: stable and Fixes: tags. (Chris) - Fix the function docbook comment.

2021-03-24drm/amdgpu/display: restore AUX_DPHY_TX_CONTROL for DCN2.xAlex Deucher1-2/+1
Commit 098214999c8f added fetching of the AUX_DPHY register values from the vbios, but it also changed the default values in the case when there are no values in the vbios. This causes problems with displays with high refresh rates. To fix this, switch back to the original default value for AUX_DPHY_TX_CONTROL.

2021-03-23drm/i915: Fix enabled_planes bitmaskVille Syrjälä1-2/+3
The enabled_planes bitmask was supposed to track logically enabled planes (ie. fb!=NULL and crtc!=NULL), but instead we end up putting even disabled planes into the bitmask since intel_plane_atomic_check_with_state() only takes the early exit if the plane was disabled and stays disabled. I think I misread the early said codepath to exit whenever the plane is logically disabled, which is not true. So let's fix this up properly and set the bit only when the plane actually is logically enabled.
