https://gitlab.freedesktop.org/drm/msm into drm-fixes msm-fixes for v6.3-rc2 - Fix for possible invalid ptr free in submit ioctl syncobj cleanup path. - Synchronize GMU removal in driver teardown path - a5xx preemption fixes - Fix runpm imbalance at unbind - DPU hw catalog fixes: - set DPU_MDP_PERIPH_0_REMOVED for sc8280xp as this is another chipset where the PERIPH_0 block of registers is not there - fix the DPU features supported in QCM2290 by comparing it with the downstream device tree - fix the length of registers in the sc7180_ctl from 0xe4 to 0x1dc - fix the max mixer line width for sm6115 and qcm2290 chipsets in the DPU catalog - fix the scaler version on sm8550, sc8280xp, sm8450, sm8250, sm8350 and sm6115. This was incorrectly populated on the SW version of the scaler library and not the scaler HW version - Drop dim layer support for msm8998 as its not indicated to be supported in the downstream DTSI - fix the DPU_CLK_CTRL bits for msm 8998 sspp blocks - Use DPU_CLK_CTRL_DMA* prefix instead of DPU_CLK_CTRL_CURSOR* for all chipsets for the DMA sspp blocks - fix the ping-pong block base address for sc7280 in the DPU HW catalog - Fix stack corruption issue in the dpu_hw_ctl_setup_blendstage() function as it was causing a negative left shift by protecting against an invalid index - Clear the DSPP reservations in dpu_rm_release(). This was missed out and as as result the DSPP was not released from the resource manager global state.

2023-03-03drm/msm/dpu: fix stack smashing in dpu_hw_ctl_setup_blendstageDmitry Baryshkov1-1/+3

2023-02-22drm/msm/adreno: fix runtime PM imbalance at unbindJohan Hovold1-1/+2
A recent commit moved enabling of runtime PM from adreno_gpu_init() to adreno_load_gpu() (called on first open()), which means that unbind() may now be called with runtime PM disabled in case the device was never opened in between. Make sure to only forcibly suspend and disable runtime PM at unbind() in case runtime PM has been enabled to prevent a disable count imbalance. This specifically avoids leaving runtime PM disabled when the device is later opened after a successful bind: msm_dpu ae01000.display-controller: [drm:adreno_load_gpu [msm]] *ERROR* Couldn't power up the GPU: -13 Fixes: 4b18299b3365 ("drm/msm/adreno: Defer enabling runpm until hw_init()") Reported-by: Bjorn Andersson <quic_bjorande@quicinc.com> Link: https://lore.kernel.org/lkml/20230203181245.3523937-1-quic_bjorande@quicinc.com Cc: stable@vger.kernel.org # 6.0 Signed-off-by: Johan Hovold <johan+linaro@kernel.org> Patchwork: https://patchwork.freedesktop.org/patch/523549/ Link: https://lore.kernel.org/r/20230221101430.14546-2-johan+linaro@kernel.org Signed-off-by: Rob Clark <robdclark@chromium.org>

2023-02-22drm/msm/a6xx: Make GPU destroy a bit saferDouglas Anderson2-1/+3
If, for whatever reason, we're trying process adreno_runtime_resume() at the same time that a6xx_destroy() is running then things can go boom. Specifically adreno_runtime_resume() will eventually call a6xx_pm_resume() and that may try to resume the gmu. Let's grab the GMU lock as we're destroying the GMU. That will solve the race because a6xx_pm_resume() grabs the same lock. That makes the access of `gmu->initialized` in a6xx_gmu_resume() safe. We'll also return an error code in a6xx_gmu_resume() if we see that `gmu->initialized` was false. If this happens we'll bail out of the rest of a6xx_pm_resume(), which is good because the rest of that function is also not good to do if we're racing with a6xx_destroy().

2023-02-21drm/fb-helper: Remove drm_fb_helper_unprepare() from drm_fb_helper_fini()Thomas Zimmermann1-0/+2
Move drm_fb_helper_unprepare() from drm_fb_helper_fini() into the calling fbdev implementation. Avoids a possible stale mutex with generic fbdev code. As indicated by its name, drm_fb_helper_prepare() prepares struct drm_fb_helper before setting up the fbdev support with a call to drm_fb_helper_init(). In legacy fbdev emulation, this happens next to each other. If successful, drm_fb_helper_fini() later tear down the fbdev device and also unprepare via drm_fb_helper_unprepare(). Generic fbdev emulation prepares struct drm_fb_helper immediately after allocating the instance. It only calls drm_fb_helper_init() as part of processing a hotplug event. If the hotplug-handling fails, it runs drm_fb_helper_fini(). This unprepares the fb-helper instance and the next hotplug event runs on stale data. Solve this by moving drm_fb_helper_unprepare() from drm_fb_helper_fini() into the fbdev implementations. Call it right before freeing the fb-helper instance.

2023-01-26drm/msm/hdmi: switch hdmi_pll_8960 to use parent_dataDmitry Baryshkov1-3/+3
Replace parent_names usage with parent_data. Note, that this makes the PLL default to board's `pxo_board' clock rather than just `pxo' clock, as we are on a way to deprecate the global cxo/pxo clocks.

2023-01-26drm/msm/dsi: properly handle the case of empty OPP table in ↵Dmitry Baryshkov1-9/+10
dsi_mgr_bridge_mode_valid It was left unnoticed during the review that even if there is no OPP table in device tree, one will be created by a call to the function devm_pm_opp_set_clkname(). This leads to dsi_mgr_bridge_mode_valid() rejecting all modes if DT contains no OPP table for the DSI host. Rework dsi_mgr_bridge_mode_valid() to handle this case by actually checking that the table is populated with frequency entries before returning an error.

Initialize the fb-helper's preferred_bpp field early from within drm_fb_helper_prepare(); instead of the later client hot-plugging callback. This simplifies the generic fbdev setup function.
