Use DRM_FORMAT_HOST_XRGB8888, so we are using the correct format code on bigendian machines. Also set the quirk_addfb_prefer_host_byte_order mode_config bit so drm_mode_addfb() asks for the correct format code. Create our own plane and use drm_crtc_init_with_planes() instead of depending on the default created by drm_crtc_init(). That way the plane format list is correct on bigendian machines. Also re-add the framebuffer format check dropped by "df2052cc92 bochs: convert to drm_fb_helper_fbdev_setup/teardown". With this patch applied...

This came out of some debugging I was doing to figure out how BE mode works on this hardware. Among other things, it came out that we're not exposing 16-bpp mode support and that the ARGB8888 mode that we do expose is broken. Also the overlay logic was pretty broken, I must have only tested with very "normal" overlay buffer sizes with modetest before. That said, this code has only

This was all kicked off by me figuring out how the PPC byteswap thing worked. In the end, we're keeping the implicit byteswap based on architecture, but also expose the correctly supported formats, and fix some overlay details. Overlay framebuffers have various funky requirements that should be enforced at framebuffer creation time (these are set apart by their YUV formats). Further, I

The only corner case is radeon, that does supports > async but doesn't support planes. The primary plane will alwyas exist (drm_crtc_init() will create one for the old drivers that don't do it explicitly). So you should be able to convert radeon as well. And looks like some pre-dc amdgpu stuff is in a similar situation. That should presumably allow the old flag to be removed entirely? Hmm, I suppose drm_getcap() would need a bit...

Hi all, First thing first: It works, I now no longer have a few dropped frames every 10s on my testbox here with the pageflip i-g-t tests. Random notes: - New design has per-crtc locks to protect the crtc input-side (pageflip, cursor) for r/w and the output state of the crtc (mode, dpms) as read-only. It also required completely revamped fb lifecycle management, those are now refcounted

Hi! While trying to get CLUT support for the atmel_hlcdc driver, and specifically for the emulated fbdev interface, I received some push-back that my feeble in-driver attempts should be solved by the core. This is my attempt to do it right. Boris and Daniel, was this approximately what you had in mind? I have obviously not tested all of this with more than a compile, but the first patch is
