[PATCH v2] drm/i915: Try EDID bitbanging on HDMI after failed read

The ACK/NACK implementation as found in e.g. the G965 has the falling clock edge and the release of the data line after the ACK for the received byte happen at the same time. This is conformant with the I2C specification, which allows a zero hold time, see footnote [3]: "A device must internally

[RFC 6/7] drm/fb-helper: Add generic fbdev emulation

Add generic fbdev emulation which uses a drm_file to get a dumb_buffer and drm_framebuffer. The buffer is exported and vmap/mmap called on the dma-buf. Signed-off-by: Noralf Trønnes --- drivers/gpu/drm/drm_fb_helper.c | 289

[RFC 5/7] drm: Handle fbdev emulation in core

[RFC 3/7] drm/fb-helper: Don't restore if fbdev is not in use

Keep track of fbdev users and only restore fbdev in drm_fb_helper_restore_fbdev_mode_unlocked() when in use. This avoids fbdev being restored in drm_driver.last_close when nothing uses it. Additionally fbdev is turned off when the last user is closing. fbcon is a user in this context.

[RFC 0/7] drm: Add generic fbdev emulation

This patchset explores the possibility of having generic fbdev emulation in DRM for drivers that supports dumb buffers which they can export. I was about to polish up my 'vmalloc BO helper' series, which has fbdev support, when this idea[1] of Laurent popped into my mind: Ideally I'd like to

[RFC 2/7] drm/fb-helper: Ensure driver module is pinned in fb_open()

If struct fb_ops is defined in a library like cma, fb_open() and fbcon takes a ref on the library instead of the driver module. Use fb_ops.fb_open/fb_release to ensure that the driver module is pinned. Add drm_fb_helper_fb_open() and drm_fb_helper_fb_release() to DRM_FB_HELPER_DEFAULT_OPS().

[RFC 1/7] drm: provide management functions for drm_file

From: David Herrmann Rather than doing drm_file allocation/destruction right in the fops, lets provide separate helpers. This decouples drm_file management from the still-mandatory drm-fops. It prepares for use of drm_file without the fops, both by possible separate fops
