drm/vc4: Use pm_runtime_resume_and_get to fix pm_runtime_get_sync() usage

2022-04-27T12:38:59+00:00

[ Upstream commit 3d0b93d92a2790337aa9d18cb332d02356a24126 ] If the device is already in a runtime PM enabled state pm_runtime_get_sync() will return 1. Also, we need to call pm_runtime_put_noidle() when pm_runtime_get_sync() fails, so use pm_runtime_resume_and_get() instead. this function will handle this.

drm/panel/raspberrypi-touchscreen: Initialise the bridge in prepare

2022-04-27T12:38:59+00:00

[ Upstream commit 5f18c0782b99e26121efa93d20b76c19e17aa1dd ] The panel has a prepare call which is before video starts, and an enable call which is after. The Toshiba bridge should be configured before video, so move the relevant power and initialisation calls to prepare.

drm/panel/raspberrypi-touchscreen: Avoid NULL deref if not initialised

[ Upstream commit f92055ae0acb035891e988ce345d6b81a0316423 ] If a call to rpi_touchscreen_i2c_write from rpi_touchscreen_probe fails before mipi_dsi_device_register_full is called, then in trying to log the error message if uses ts->dsi->dev when it is still NULL.

drm/msm/mdp5: check the return of kzalloc()

2022-04-27T12:38:56+00:00

[ Upstream commit 047ae665577776b7feb11bd4f81f46627cff95e7 ] kzalloc() is a memory allocation function which can return NULL when some internal memory errors happen. So it is better to check it to prevent potential wrong memory access. Besides, since mdp5_plane_reset() is void type, so we should better set `plane-state` to NULL after releasing it.

drm/i915/display/psr: Unset enable_psr2_sel_fetch if other checks in intel_psr2_config_valid() fails

2022-04-27T12:38:54+00:00

[ Upstream commit bb02330408a7bde33b5f46aa14fd5d7bfe6093b7 ] If any of the PSR2 checks after intel_psr2_sel_fetch_config_valid() fails, enable_psr2_sel_fetch will be kept enabled causing problems in the functions that only checks for it and not for has_psr2. So here moving the check that do not depend on enable_psr2_sel_fetch and for the remaning ones jumping to a section that unset enable_psr2_sel_fetch in case of failure to support PSR2.

drm/i915: Sunset igpu legacy mmap support based on GRAPHICS_VER_FULL

2022-04-20T07:34:21+00:00

commit 1acb34e7dd7720a1fff00cbd4d000ec3219dc9d6 upstream. The intent of the version check in the mmap ioctl was to maintain support for existing platforms (i.e., ADL/RPL and earlier), but drop support on all future igpu platforms. As we've seen on the dgpu side, the hardware teams are using a more fine-grained numbering system for IP version numbers these days, so it's possible the version number associated with our next igpu could be some form of "12.xx" rather than 13 or higher. Comparing against the full ver.release number will ensure the intent of the check is maintained no matter what numbering the hardware teams settle on.

drm/amdgpu: Enable gfxoff quirk on MacBook Pro

commit 4593c1b6d159f1e5c35c07a7f125e79e5a864302 upstream. Enabling gfxoff quirk results in perfectly usable graphical user interface on MacBook Pro (15-inch, 2019) with Radeon Pro Vega 20 4 GB. Without the quirk, X server is completely unusable as every few seconds there is gpu reset due to ring gfx timeout.
