2017-03-27drm: bochs: Prevent double-free of fb helperGabriel Krisman Bertazi1-1/+3
If fbdev registration fails for whatever reason, the error path of bochs_fbdev_init() will call bochs_fbdev_fini(), but since an fbdev initialization error is not fatal to the probe function, a subsequent device removal will try to call bochs_fbdev_fini() again, hitting the Oops below. This was detected by 0-day with a failing framebuffer registration and CONFIG_DEBUG_TEST_DRIVER_REMOVE=y. This reproduces the scenario I mentioned above at insmod time, because the test attempts to remove the device right after probing. root@debian:~# insmod bochs-drm.ko [ 17.609635] [drm] Found bochs VGA, ID 0xb0c0.

2017-02-02drm: Rely on mode_config data for fb_helper initializationGabriel Krisman Bertazi1-2/+1
Instead of receiving the num_crts as a parameter, we can read it directly from the mode_config structure. I audited the drivers that invoke this helper and I believe all of them initialize the mode_config struct accordingly, prior to calling the fb_helper. I used the following coccinelle hack to make this transformation, except for the function headers and comment updates. The first and second rules are split because I couldn't find a way to remove the unused temporary variables at the same time I removed the parameter. // <smpl> @r@ expression A,B,D,E; identifier C; @@ ( - drm_fb_helper_init(A,B,C,D) + drm_fb_helper_init(A,B,D) | - drm_fbdev_cma_init_with_funcs(A,B,C,D,E) + drm_fbdev_cma_init_with_funcs(A,B,D,E) | - drm_fbdev_cma_init(A,B,C,D) + drm_fbdev_cma_init(A,B,D) ) @@ expression A,B,C,D,E; @@ ( - drm_fb_helper_init(A,B,C,D) + drm_fb_helper_init(A,B,D) | - drm_fbdev_cma_init_with_funcs(A,B,C,D,E) + drm_fbdev_cma_init_with_funcs(A,B,D,E) | - drm_fbdev_cma_init(A,B,C,D) + drm_fbdev_cma_init(A,B,D) ) @@ identifier r.C; type T; expression V; @@ - T C; <... when != C - C = V; ...> // </smpl> Changes since v1: - Rebased on top of the tip of drm-misc-next. - Remove mention to sti since a proper fix got merged.

2016-12-18drm: Don't include <drm/drm_encoder.h> in <drm/drm_crtc.h>Laurent Pinchart1-0/+1
<drm/drm_crtc.h> used to define most of the in-kernel KMS API. It has now been split into separate files for each object type, but still includes most other KMS headers to avoid breaking driver compilation. As a step towards fixing that problem, remove the inclusion of <drm/drm_encoder.h> from <drm/drm_crtc.h> and include it instead where appropriate. Also remove the forward declarations of the drm_encoder and drm_encoder_helper_funcs structures from <drm/drm_crtc.h> as they're not needed in the header. <drm/drm_encoder.h> now has to include <drm/drm_mode.h> and contain a forward declaration of struct drm_encoder in order to allow including it as the first header in a compilation unit.

The qemu stdvga can be configured with a wide range of video memory, from 1 MB to 256 MB (default is 16 MB). In case it is configured with only 1 or 2 MB it isn't really usable with bochsdrm, due to depths other than 32bpp not being supported so that isn't enough memory for a reasonable sized framebuffer. So skip the device and let vgacon or vesafb+fbcon handle the it. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2016-08-12drm/fb-helper: Add a dummy remove_conflicting_framebuffersDaniel Vetter1-1/+2
Lots of drivers don't properly compile without this when CONFIG_FB=n. It's kinda a hack, but since CONFIG_FB doesn't stub any fucntions when it's disabled I think it makes sense to add it to drm_fb_helper.h. Long term we probably need to rethink all the logic to unload firmware framebuffer drivers, at least if we want to be able to move away from CONFIG_FB and fbcon. v2: Unfortunately just stubbing out remove_conflicting_framebuffers in drm_fb_helper.h upset gcc about static vs. non-static declarations, so a new wrapper it needs to be.
