drm/panfrost: Check for error num after setting mask

2022-04-08T12:05:57Z

[ Upstream commit 44ab30b056149bd59dd7989a593dd25ead6007fd ] Because of the possible failure of the dma_supported(), the dma_set_mask_and_coherent() may return error num. Therefore, it should be better to check it and return the error if fails.

drm: Return error codes from struct drm_driver.gem_create_object

2022-01-27T11:02:19Z

[ Upstream commit 4ff22f487f8c26b99cbe1678344595734c001a39 ] GEM helper libraries use struct drm_driver.gem_create_object to let drivers override GEM object allocation. On failure, the call returns NULL. Change the semantics to make the calls return a pointer-encoded error. This aligns the callback with its callers. Fixes the ingenic driver, which already returns an error pointer. Also update the callers to handle the involved types more strictly.

drm/panfrost: simplify getting .driver_data

We should get 'driver_data' from 'struct device' directly. Going via platform_device is an unneeded step back and forth.

drm/panfrost: Calculate lock region size correctly

2021-09-17T10:47:26Z

It turns out that when locking a region, the region must be a naturally aligned power of 2. The upshot of this is that if the desired region crosses a 'large boundary' the region size must be increased significantly to ensure that the locked region completely covers the desired region. Previous calculations (including in kbase for the proprietary driver) failed to take this into account. Since it's known that the lock region must be naturally aligned we can compute the required size by looking at the highest bit position which changes between the start/end of the lock region (subtracting 1 from the end because the end address is exclusive). The start address is then aligned based on the size (this is technically unnecessary as the hardware will ignore these bits, but the spec advises to do this "to avoid confusion").

panfrost: Don't cleanup the job if it was successfully queued

2021-09-02T09:11:58Z

The labels are misleading. Even though they are all prefixed with 'fail_' the success case also takes that path, and we should definitely not cleanup the job if it's been queued. While at it, let's rename those labels so we don't do the same mistake again.
