[PATCH v2 13/25] drm/msm: Compute dumb-buffer sizes with drm_mode_size_dumb()
Call drm_mode_size_dumb() to compute dumb-buffer scanline pitch and buffer size. The hardware requires the scnaline pitch to be a multiple of 32 pixels. Therefore compute the byte size of 32 pixels in the given color mode and align the pitch accordingly.

[PATCH 00/17] cirrus: Modernize the cirrus driver
Update the cirrus driver to follow current best practices. While the driver's hardware is obsolete, the cirrus driver is still one of the go-to modules to learn about writing a DRM driver. So keep it in good shape. Patches 1 to 3 simplify blitting and convert it to the DRM's current helpers. Patches 4 to 8 replace simple-KMS helpers with DRM's regular atomic helpers. The former are

[PATCH v2 00/25] drm/dumb-buffers: Fix and improve buffer-size calculation
Dumb-buffer pitch and size is specified by width, height, bits-per-pixel plus various hardware-specific alignments. The calculation of these values is inconsistent and duplicated among drivers. The results for formats with bpp < 8 are incorrect. This series fixes this for most drivers. Default scanline pitch and buffer size are now calculated with the existing 4CC helpers. There is a new
