similar to: [PATCH v3 2/5] drm/bochs: pass framebuffer to bochs_hw_setbase

Call it from bochs_hw_setfb(). This also allows to make bochs_hw_setformat static.

If bo->width doesn't match fb->width the driver fails to configure the display correctly, resulting in a scrambled display. Fix it.

No need to store that, struct drm_framebuffer has all we need. Also update VBE_DISPI_INDEX_VIRT_WIDTH register, otherwise we'll have a fixes broken display in case pitch != width * cpp. Signed-off-by: Gerd Hoffmann <kraxel at redhat.com> --- drivers/gpu/drm/bochs/bochs.h | 2 -- drivers/gpu/drm/bochs/bochs_hw.c | 18 +++++++++--------- drivers/gpu/drm/bochs/bochs_kms.c | 2 +-

The driver doesn't consider framebuffer pitch and offset, leading to a wrong display in case offset != 0 or pitch != width * bpp. Fix it.

Call bochs_unload via drm_driver.release to make sure we release stuff when it is safe to do so. Use drm_dev_{enter,exit,unplug} to avoid touching hardware after device removal.

Create a separate bochs_hw_setformat function to configure the framebuffer format (actually just the byteorder).

Add bochs_hw_set_*_endian() helper functions, to set the framebuffer byteorder at mode set time. Support both DRM_FORMAT_XRGB8888 and DRM_FORMAT_BGRX8888 framebuffer formats, no matter what the native machine byte order is.

Call drm_dev_unregister() first in bochs_pci_remove(). Hook bochs_unload() into the new .release callback, to make sure cleanup is done when all users are gone. Add ready bool to state struct and move bochs_hw_fini() call from bochs_unload() to bochs_pci_remove() to make sure hardware is not touched after bochs_pci_remove returns.

Recent qemu (latest master branch, upcoming 3.1 release) got support for EDID data. This patch adds guest driver support.

Check header before trying to read the complete edid blob, to avoid the log being spammed in case qemu has no edid support (old qemu or edid support turned off).
