drm/bochs: Fix the ID mismatch error

2019-02-28T04:05:33+00:00

When running RISC-V QEMU with the Bochs device attached via PCIe the
probe of the Bochs device fails with:
    [drm:bochs_hw_init] *ERROR* ID mismatch

This was introduced by this commit:
    7780eb9ce8 bochs: convert to drm_dev_register

To fix the error we ensure that pci_enable_device() is called before
bochs_load().

Fixes: 7780eb9ce80f ("bochs: convert to drm_dev_register")

drm/ttm: initialize globals during device init (v2)

2018-11-05T19:21:21+00:00

Make sure that the global BO state is always correctly initialized.

This allows removing all the device code to initialize it.

v2: fix up vbox (Alex)

drm/ttm: use a static ttm_mem_global instance

2018-11-05T19:21:18+00:00

As the name says we only need one global instance of ttm_mem_global.

Drop all the driver initialization and just use a single exported
instance which is initialized during BO global initialization.

drm/ttm: Rename ttm_bo_global_{init,release}() to ttm_bo_global_ref_{,}()

2018-11-05T19:20:52+00:00

The functions ttm_bo_global_init() and ttm_bo_global_release() do not
receive an argument of type struct ttm_bo_global. Both take a struct
drm_global_reference that contains points to a struct ttm_bo_global_ref.
Renaming them reflects this.

drm/bochs: add edid support.

2018-10-30T13:42:28+00:00

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

EDID support in qemu is not (yet) enabled by default, so please use
'qemu -device VGA,edid=on' for testing.

drm/bochs: Replace drm_gem_object_unreference_unlocked with put function

2018-10-01T07:21:36+00:00

This patch unifies the naming of DRM functions for reference counting
of struct drm_gem_object. The resulting code is more aligned with the
rest of the Linux kernel interfaces.

drm/bochs: support changing byteorder at mode set time

2018-09-25T12:49:49+00:00

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.

drm/bochs: fix DRM_FORMAT_* handling for big endian machines.

2018-09-25T12:49:49+00:00

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 both ADDFB and ADDFB2 ioctls work correctly in
the bochs-drm.ko driver on big endian machines.  Without the patch only
ADDFB (which still seems to be used by the majority of userspace) works
correctly.
