drm/msm: change gem->vmap() to get/put

2016-07-16T14:09:07Z

Before we can add vmap shrinking, we really need to know which vmap'ings are currently being used. So switch to get/put interface. Stubbed put fxns for now. Signed-off-by: Rob Clark

Linux 4.7-rc5 The fsl-dcu pull needs -rc3 so go to -rc5 for now.

drm/msm: deal with exhausted vmap space better

2016-06-04T18:45:48Z

Some, but not all, callers of obj->vmap() would check if return IS_ERR(). So let's actually return an error if vmap() fails. And fixup the call-sites that were not handling this properly. Signed-off-by: Rob Clark

drm/msm: Nuke dummy gamma_set/get functions

2016-05-31T13:26:41Z

Again the fbdev emulation gamma_set/get functions are only needed for drivers that try to also use 8bpp paletted mode. Which msm doesn't, so this is dead code. Let's rip it out.

drm/msm: remove unused variable

2016-02-11T10:48:39Z

After the drm_device_is_unplugged() was removed, the 'dev' variable is now unused, and we get a warning for that: drivers/gpu/drm/msm/msm_fbdev.c: In function 'msm_fbdev_mmap': drivers/gpu/drm/msm/msm_fbdev.c:65:21: error: unused variable 'dev' [-Werror=unused-variable] This removes the variable as well.

drm/msm: Use unlocked gem unreferencing

2015-12-14T16:49:44Z

For drm_gem_object_unreference callers are required to hold dev->struct_mutex, which these paths don't. Enforcing this requirement has become a bit more strict with commit ef4c6270bf2867e2f8032e9614d1a8cfc6c71663 Author: Daniel Vetter Date: Thu Oct 15 09:36:25 2015 +0200 drm/gem: Check locking in drm_gem_object_unreference Cc: Rob Clark Signed-off-by: Daniel Vetter Signed-off-by: Rob Clark

drm/msm: Use new drm_fb_helper functions

2015-08-06T12:12:58Z

Use the newly created wrapper drm_fb_helper functions instead of calling core fbdev functions directly. They also simplify the fb_info creation. Cc: Rob Clark Cc: Stephane Viau Cc: Hai Li Signed-off-by: Archit Taneja Signed-off-by: Daniel Vetter

drm/msm: add support for "stolen" mem

2015-04-01T23:29:33Z

Add support to use the VRAM carveout (if specified in dtb) for fbdev scanout buffer. This allows drm/msm to take over a bootloader splash- screen, and avoids corruption on screen that results if the kernel uses memory that is still being scanned out for itself. Signed-off-by: Rob Clark
