drm/panfrost: Fix shrinker list corruption by madvise IOCTL

2022-07-22T08:21:21Z

commit 9fc33eaaa979d112d10fea729edcd2a2e21aa912 upstream. Calling madvise IOCTL twice on BO causes memory shrinker list corruption and crashes kernel because BO is already on the list and it's added to the list again, while BO should be removed from the list before it's re-added. Fix it.

drm/panfrost: Put mapping instead of shmem obj on panfrost_mmu_map_fault_addr() error

2022-07-22T08:21:21Z

commit fb6e0637ab7ebd8e61fe24f4d663c4bae99cfa62 upstream. When panfrost_mmu_map_fault_addr() fails, the BO's mapping should be unreferenced and not the shmem object which backs the mapping.

drm/panfrost: Job should reference MMU not file_priv

2022-06-14T16:45:03Z

[ Upstream commit 6e516faf04317db2c46cbec4e3b78b4653a5b109 ] For a while now it's been allowed for a MMU context to outlive it's corresponding panfrost_priv, however the job structure still references panfrost_priv to get hold of the MMU context. If panfrost_priv has been freed this is a use-after-free which I've been able to trigger resulting in a splat. To fix this, drop the reference to panfrost_priv in the job structure and add a direct reference to the MMU structure which is what's actually needed.

drm-misc-next for v5.18: UAPI Changes: Cross-subsystem Changes: - Improve performance of some fbdev ops, in some cases up to 6x faster. Core Changes: - Some small DP fixes. - Find panels in subnodes of OF devices, and add of_get_drm_panel_display_mode to retrieve mode. - Add drm_object_property_get_default_value and use it for resetting zpos in plane state reset, removing the need for individual drivers to do it. - Same for color encoding and color range props. - Update panic handling todo doc. - Add todo that format conversion helpers should be sped up similarly to fbdev ops. Driver Changes: - Add panel orientation property to simpledrm for quirked panels. - Assorted small fixes to tiny/repaper, nouveau, stm, omap, ssd130x. - Add crc support to stm/ltdc. - Add MIPI DBI compatible SPI driver - Assorted small fixes to tiny panels and bridge drivers. - Add AST2600 support to aspeed.

drm/panfrost: Handle IDVS_GROUP_SIZE feature

2022-02-11T16:43:48Z

The IDVS group size feature was missing. It is used on some Bifrost and Valhall GPUs, and is the last kernel-relevant Bifrost feature we're missing. This feature adds an extra IDVS group size field to the JM_CONFIG register. In kbase, the value is configurable via the device tree; kbase uses 0xF as a default if no value is specified. Until we find a device demanding otherwise, let's always set the 0xF default on devices which support this feature mimicking kbase's behaviour. Tuning this register slightly improves performance of index-driven vertex shading. On Mali-G52 (with Mesa), overall glmark2 score is improved from 1026 to 1037. Geometry-heavy scenes like -bshading are improved from 1068 to 1098.
