Testing on a Polaris11 gpu with DCE-11.2 suggests that it seems to work fine there, so optimistically enable it for DCE-11 and later. v2: drop DCE 11.0 hunk.

2020-05-18drm/amdgpu: Add autodump debugfs node for gpu reset v8Jiange Zhao4-1/+87
When GPU got timeout, it would notify an interested part of an opportunity to dump info before actual GPU reset. A usermode app would open 'autodump' node under debugfs system and poll() for readable/writable. When a GPU reset is due, amdgpu would notify usermode app through wait_queue_head and give it 10 minutes to dump info. After usermode app has done its work, this 'autodump' node is closed. On node closure, amdgpu gets to know the dump is done through the completion that is triggered in release(). There is no write or read callback because necessary info can be obtained through dmesg and umr. Messages back and forth between usermode app and amdgpu are unnecessary. v2: (1) changed 'registered' to 'app_listening' (2) add a mutex in open() to prevent race condition v3 (chk): grab the reset lock to avoid race in autodump_open, rename debugfs file to amdgpu_autodump, provide autodump_read as well, style and code cleanups v4: add 'bool app_listening' to differentiate situations, so that the node can be reopened; also, there is no need to wait for completion when no app is waiting for a dump. v5: change 'bool app_listening' to 'enum amdgpu_autodump_state' add 'app_state_mutex' for race conditions: (1)Only 1 user can open this file node (2)wait_dump() can only take effect after poll() executed. (3)eliminated the race condition between release() and wait_dump() v6: removed 'enum amdgpu_autodump_state' and 'app_state_mutex' removed state checking in amdgpu_debugfs_wait_dump Improve on top of version 3 so that the node can be reopened. v7: move reinit_completion into open() so that only one user can open it. v8: remove complete_all() from amdgpu_debugfs_wait_dump().

2020-05-18drm/exynos-vidi: convert platform driver to use dev_groupsEmil Velikov1-18/+8
Platform drivers now have the option to have the platform core create and remove any needed sysfs attribute files. So take advantage of that and do not register "by hand" a sysfs file.

2020-05-18drm/exynos: dsi: Remove bridge node reference in error handling path in ↵Christophe JAILLET1-5/+15
probe function 'exynos_dsi_parse_dt()' takes a reference to 'dsi->in_bridge_node'. This must be released in the error handling path. In order to do that, add an error handling path and move the 'exynos_dsi_parse_dt()' call from the beginning to the end of the probe function to ease the error handling path. This function only sets some variables which are used only in the 'transfer' function. The call chain is: .transfer --> exynos_dsi_host_transfer --> exynos_dsi_init --> exynos_dsi_enable_clock (use burst_clk_rate and esc_clk_rate) --> exynos_dsi_set_pll (use pll_clk_rate) While at it, also handle cases where 'component_add()' fails. This patch is similar to commit 70505c2ef94b ("drm/exynos: dsi: Remove bridge node reference in removal") which fixed the issue in the remove function.

2020-05-18drm/exynos: mixer: Fix enabling of the runtime power managementMarek Szyprowski1-2/+4
Runtime power management is essential for the Exynos Mixer driver operation. It should be enabled before adding its DRM component, because in some cases (when deferred probe takes place due to the IOMMU availability) the DRM driver might be initialized directly from the Mixer's component_add() call, what results in starting the driver operation without enabling the runtime power management.

2020-05-18drm/exynos: gem: Get rid of the internal 'pages' arrayMarek Szyprowski3-123/+42
Internal pages array and scatter-list for them is not really needed for anything. FBDev emulation can simply rely on the DMA-mapping framework to create a proper kernel mapping for the buffer, while all other buffer use cases don't really need that array at all.
