drm/bochs: Don't grab dev->struct_mutex for in mmap offset ioctl

2015-08-10T11:37:04+00:00

Since David Herrmann's mmap vma manager rework we don't need to grab dev->struct_mutex any more to prevent races when looking up the mmap offset. Drop it and instead don't forget to use the unref_unlocked variant (since the drm core still cares). Reviewed-by: Thierry Reding Signed-off-by: Daniel Vetter

drm/bochs: Use new drm_fb_helper functions

2015-08-06T12:13:06+00:00

Use the newly created wrapper drm_fb_helper functions instead of calling core fbdev functions directly. They also simplify the fb_info creation. v3: - Don't touch remove_conflicting_framebuffers v2: - remove unused variable device in bochsfb_create Cc: David Airlie Cc: Gerd Hoffmann Cc: Daniel Vetter Signed-off-by: Archit Taneja Signed-off-by: Daniel Vetter

drm/bochs: disable video before changing video mode

2015-03-31T22:28:15+00:00

qemu and simics simulators both seem to expect that video should be disabled before changing the video mode. references: http://git.qemu.org/?p=qemu.git;a=blob;f=hw/display/vga.c;h=c0f7b343bbab586c8593d29c7a765f1e6ca3662c;hb=HEAD#l727 http://wiki.osdev.org/Bochs_VBE_Extensions#Setting_display_resolution_and_bit_depth Signed-off-by: Chris Ruffin Reviewed-by: Gerd Hoffmann Signed-off-by: Dave Airlie

drm/fb-helper: Propagate errors from initial config failure

2015-01-21T13:57:03+00:00

Make drm_fb_helper_initial_config() return an int rather than a bool so that the error can be properly propagated. While at it, update drivers to propagate errors further rather than just ignore them. v2: - cirrus: No cleanup is required, the top-level cirrus_driver_load() will do it as part of cirrus_driver_unload() in its cleanup path.

drm/bochs: Remove dummy ->load_lut() implementation

2014-12-10T12:51:31+00:00

The ->load_lut() callback is optional, therefore a dummy implementation is not needed. Cc: Gerd Hoffmann Signed-off-by: Thierry Reding Signed-off-by: Daniel Vetter

bochs: add page_flip

2014-11-20T01:27:31+00:00

Implement crtc page_flip callback for bochsdrm. The qemu stdvga has no vblank signaling, so we have to fake it. We do so by instantly calling drm_send_vblank_event. Tested with kmscon. Signed-off-by: Gerd Hoffmann Signed-off-by: Dave Airlie

bochs: fix bochsdrmfb mmap

2014-11-20T01:27:09+00:00

Remove the mapping offset from the bo backing the fbdev framebuffer. Wire up fbdev mmap function to map the backing bo using ttm_fbdev_mmap. With that patch in place mmap(/dev/fb0) works as expected. Signed-off-by: Gerd Hoffmann Signed-off-by: Dave Airlie

bochs: add endian switching support

2014-11-20T01:26:54+00:00

Recently (qemu 2.2+) the qemu stdvga got a register to switch the vga framebuffer endianness. This patch adds code to explicitly set the endianness of the framebuffer. In most cases this has no effect as the default is guest architecture endianness. It is needed though in case a architecture supports both big and little endian, i.e. for ppc64le.

drm: Move drm_crtc_init from drm_crtc.h to drm_plane_helper.h

2014-11-04T23:14:55+00:00

Just a bit of OCD cleanup on headers - this function isn't the core interface any more but just a helper for drivers who haven't yet transitioned to universal planes. Put the declaration at the right spot and sprinkle necessary #includes over all drivers. Maybe this helps to encourage driver maintainers to do the switch. v2: Fix #include ordering for tegra, reported by 0-day builder. v3: Include required headers, reported by Thierry.
