drm: switch drm_fb_xrgb8888_to_rgb888_dstclip to accept __iomem dst

2019-04-10T19:11:12Z

Not all archs have the __io_virt() macro, so cirrus can't simply convert pointers that way. The drm format helpers have to use memcpy_toio() instead. This patch makes drm_fb_xrgb8888_to_rgb888_dstclip() accept a __iomem dst pointer and use memcpy_toio() instead of memcpy(). The helper function (drm_fb_xrgb8888_to_rgb888_line) has been changed to process a single scanline.

drm: switch drm_fb_memcpy_dstclip to accept __iomem dst

2019-04-10T19:11:11Z

Not all archs have the __io_virt() macro, so cirrus can't simply convert pointers that way. The drm format helpers have to use memcpy_toio() instead. This patch makes drm_fb_memcpy_dstclip() accept a __iomem dst pointer and use memcpy_toio() instead of memcpy(). With that separating out the memcpy loop into the drm_fb_memcpy_lines() helper isn't useful any more, so move the code back into the calling functins.

drm: add drm_fb_xrgb8888_to_rgb888_dstclip()

2019-04-08T04:59:27Z

Simliar to drm_fb_xrgb8888_to_rgb565_dstclip() but converts to rgb888 instead of rgb565. Signed-off-by: Gerd Hoffmann Reviewed-by: Noralf Trønnes Link: http://patchwork.freedesktop.org/patch/msgid/20190405095219.9231-5-kraxel@redhat.com

drm: add drm_fb_xrgb8888_to_rgb565_dstclip()

2019-04-08T04:59:27Z

It is a drm_fb_xrgb8888_to_rgb565() variant which checks the clip rectangle for the destination too. Common code between drm_fb_xrgb8888_to_rgb565() and drm_fb_xrgb8888_to_rgb565_dstclip() was factored out into the drm_fb_xrgb8888_to_rgb565_lines() helper function.
