The memory used to be allocated with devres helpers and released automatically. In rare circumstances, the memory's release could have happened before the DRM device got released, which would have caused memory corruption of some kind. Now we're embedding the data structures in struct hibmc_drm_private. The whole release problem has been resolved, because struct hibmc_drm_private is allocated with drmm_kzalloc and always released with the DRM device. Signed-off-by:

In order to successfully read ID of the MTP panel the panel MTP control page must be unlocked. Previously this wasn't encountered because in the setup with this panel the power wasn't ever really dropped. When power gets dropped from the panel, MTP needs to be unlocked. Acked-by:

Currently, downstream port type is only reported in debugfs. This information should be considered important since it reflects the actual physical connector type. Some userspace (e.g. window compositors) may want to show this info to a user. The 'subconnector' property is already utilized for DVI-I and TV-out for reporting connector subtype. The initial motivation for this feature came from i2c test [1]. It is supposed to be skipped on VGA connectors, but it cannot detect VGA over DP and fails instead. v2: - Ville: utilized drm_dp_is_branch() - Ville: implement DP 1.0 downstream type info - Replaced create_dp_properties with add_dp_subconnector_property - Added dp_set_subconnector_property helper v4: - Ville: add DP1.0 best assumption about subconnector - Ville: assume DVI is DVI-D - Ville: reuse Writeback enum value for Virtual subconnector - Renamed #defines: HDMI -> HDMIA, DP -> DisplayPort v5: rebase v6: - Jani Nikula: renamed a function name - Jani Nikula: addressed the issues with documentation [1]: https://bugs.freedesktop.org/show_bug.cgi?id=104097 Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: intel-gfx@lists.freedesktop.org Signed-off-by:

VKMS needs vblank interrupts enabled to capture CRC. When vblank is disabled, tests like kms_cursor_crc and kms_pipe_crc_basic getting stuck waiting for a capture that will not occur until vkms wakes up. This patch adds a helper to set composer and ensure that vblank remains enabled as long as the CRC capture is needed. It clears the execution of the following kms_cursor_crc subtests: 1. pipe-A-cursor-[size,alpha-opaque, NxN-(on-screen, off-screen, sliding, random, fast-moving])] - successful when running individually. 2. pipe-A-cursor-dpms passes again 3. pipe-A-cursor-suspend also passes The issue was initially tracked in the sequential execution of IGT kms_cursor_crc subtests: when running the test sequence or one of its subtests twice, the odd execs complete and the pairs get stuck in an endless wait. In the IGT code, calling a wait_for_vblank on preparing for CRC capture prevented the busy-wait. But the problem persisted in the pipe-A-cursor-dpms and -suspend subtests. Checking the history, the pipe-A-cursor-dpms subtest was successful when, in vkms_atomic_commit_tail, instead of using the flip_done op, it used wait_for_vblanks. Another way to prevent blocking was wait_one_vblank when enabling crtc. However, in both cases, pipe-A-cursor-suspend persisted blocking in the 2nd start of CRC capture, which may indicate that something got stuck in the step of CRC setup. Indeed, wait_one_vblank in the crc setup was able to sync things and free all kms_cursor_crc subtests. Besides, other alternatives to force enabling vblanks or prevent disabling them such as calling drm_crtc_put_vblank or modeset_enables before commit_planes + offdelay = 0, also unlock all subtests executions. Finally, due to vkms's dependence on vblank interruptions to perform tasks, this patch uses refcount to ensure that vblanks happen when enabling composer and while crc capture is needed. Cc: Rodrigo Siqueira <rodrigosiqueiramelo@gmail.com> Cc: Haneen Mohammed <hamohammed.sa@gmail.com> v2: - extract a vkms_set_composer helper - fix vblank refcounting for the disabling case v3: - make the vkms_set_composer helper static - review the credit tags Co-debugged-by:

Later we will introduce devfreq probing regulator if they are present. As regulator should be probe only one time we need to get this logic in the device_init(). panfrost_device is already taking care of devfreq_resume() and devfreq_suspend(), so it's not totally illogic to move the devfreq_init() and devfreq_fini() here.
