Revert "drm/etnaviv: Expose a few more chipspecs to userspace"

2024-04-25T14:56:20+00:00

This reverts commit 1dccdba084897443d116508a8ed71e0ac8a031a4. In userspace a different approach was choosen - hwdb. As a result, there is no need for these values. Signed-off-by: Christian Gmeiner Reviewed-by: Tomeu Vizoso Signed-off-by: Lucas Stach

drm/etnaviv: fix tx clock gating on some GC7000 variants

2024-04-25T14:52:00+00:00

commit 4bce244272513 ("drm/etnaviv: disable tx clock gating for GC7000 rev6203") accidentally applied the fix for i.MX8MN errata ERR050226 to GC2000 instead of GC7000, failing to disable tx clock gating for GC7000 rev 0x6023 as intended. Additional clean-up further propagated this issue, partially breaking the clock gating fixes added for GC7000 rev 6202 in commit 432f51e7deeda ("drm/etnaviv: add clock gating workaround for GC7000 r6202").

drm/etnaviv: Restore some id values

2024-03-07T09:57:54+00:00

The hwdb selection logic as a feature that allows it to mark some fields as 'don't care'. If we match with such a field we memcpy(..) the current etnaviv_chip_identity into ident. This step can overwrite some id values read from the GPU with the 'don't care' value. Fix this issue by restoring the affected values after the memcpy(..). As this is crucial for user space to know when this feature works as expected increment the minor version too.

drm/etnaviv: disable MLCG and pulse eater on GPU reset

2024-01-23T09:20:20+00:00

Module level clock gating and the pulse eater might interfere with the GPU reset, as they both have the potential to stop the clock and thus reset propagation to parts of the GPU. Signed-off-by: Lucas Stach Reviewed-by: Christian Gmeiner

drm/etnaviv: Drop the 'len' parameter of etnaviv_iommu_map() function

The 'len' parameter is the 4th argument, because it is not get used, so drop it. No functional change. Signed-off-by: Sui Jingfeng Signed-off-by: Lucas Stach

drm/etnaviv: Clean up etnaviv_gem_get_pages

2024-01-23T09:20:20+00:00

As in the etnaviv_gem_get_pages() function, the point to the drm_device has already been cached to the 'dev' local variable. We can use it directly, While at it, using 'unsigned int' type to count the number of pages. As the drm_prime_pages_to_sg() function takes an unsigned int type for its third argument.

drm/etnaviv: Add a helper to get the first available GPU device node

2024-01-23T09:20:20+00:00

This patch make the code in the etnaviv_pdev_probe() less twisted, and it also make it easier to drop the reference to device node after finished. Before apply this patch, there is no call to of_node_put() when done. We should call of_node_put() when done. Signed-off-by: Sui Jingfeng Signed-off-by: Lucas Stach
