2015-02-05drm/cirrus: Limit modes depending on bpp optionTakashi Iwai4-2/+15
The commit [8975626ea35a: drm/cirrus: allow 32bpp framebuffers for cirrus drm] broke X modesetting driver because cirrus driver still provides the full list of modes up to 1280x1024 while the 32bpp can support only up to 800x600. We might be able to filter out the invalid modes in mode_valid callback, but unfortunately the bpp in question can't be referred there for now (let me know if there is a better way to retrieve the bpp for the probed fb). So, instead, this patch adds the bpp module option to specify the maximal bpp explicitly and limits the resolutions in get_modes depending on its value. The default value is set to 24 so that the existing stuff keeps working. If you need a new 32bpp feature, specify cirrus.bpp=32 option explicitly.

2014-07-08drm: Introduce drm_fb_helper_prepare()Thierry Reding1-1/+3
To implement hotplug detection in a race-free manner, drivers must call drm_kms_helper_poll_init() before hotplug events can be triggered. Such events can be triggered right after any of the encoders or connectors are initialized. At the same time, if the drm_fb_helper_hotplug_event() helper is used by a driver, then the poll helper requires some parts of the FB helper to be initialized to prevent a crash. At the same time, drm_fb_helper_init() requires information that is not necessarily available at such an early stage (number of CRTCs and connectors), so it cannot be used yet. Add a new helper, drm_fb_helper_prepare(), that initializes the bare minimum needed to allow drm_kms_helper_poll_init() to execute and any subsequent hotplug events to be processed properly.

2014-03-16drm: use anon-inode instead of relying on cdevsDavid Herrmann1-1/+1
DRM drivers share a common address_space across all character-devices of a single DRM device. This allows simple buffer eviction and mapping-control. However, DRM core currently waits for the first ->open() on any char-dev to mark the underlying inode as backing inode of the device. This delayed initialization causes ugly conditions all over the place: if (dev->dev_mapping) do_sth(); To avoid delayed initialization and to stop reusing the inode of the char-dev, we allocate an anonymous inode for each DRM device and reset filp->f_mapping to it on ->open().

2014-01-23drm/cirrus: correct register values for 16bppTakashi Iwai1-2/+2
When the mode is set with 16bpp on QEMU, the output gets totally broken. The culprit is the bogus register values set for 16bpp, which was likely copied from from a wrong place.

2013-10-11drm: Add separate Kconfig option for fbdev helpersDaniel Vetter1-0/+1
For drivers which might want to disable fbdev legacy support. Select the new option in all drivers for now, so this shouldn't result in any change. Drivers need some work anyway to make fbdev support optional (if they have it implemented, that is), so the recommended way to expose this is by adding per-driver options. At least as long as most drivers don't support disabling the fbdev support. v2: Update for new drm drivers msm and rcar-du. Note that Rob's msm driver can already take advantage of this, which allows us to build msm without any fbdev depencies in the kernel! v3: Move the MODULE_* stuff from the fbdev helper file to drm_crtc_helper.c.

All drivers embed gem-objects into their own buffer objects. There is no reason to keep drm_gem_object_alloc(), gem->driver_private and ->gem_init_object() anymore. New drivers are highly encouraged to do the same. There is no benefit in allocating gem-objects separately.

2013-08-27drm: verify vma access in TTM+GEM driversDavid Herrmann1-1/+3
GEM does already a good job in tracking access to gem buffers via handles and drm_vma access management. However, TTM drivers currently do not verify this during mmap(). TTM provides the verify_access() callback to test this. So fix all drivers to actually call into gem+vma to verify access instead of always returning 0. All drivers assume that user-space can only get access to TTM buffers via GEM handles. So whenever the verify_access() callback is called from ttm_bo_mmap(), the buffer must have a valid embedded gem object. This is true for all TTM+GEM drivers. But that's why this patch doesn't touch pure TTM drivers (ie, vmwgfx). v2: Switch to drm_vma_node_verify_access() to correctly return -EACCES if access was denied.

2013-08-19drm: rip out drm_core_has_MTRR checksDaniel Vetter1-1/+1
The new arch_phys_wc_add/del functions do the right thing both with and without MTRR support in the kernel. So we can drop these additional checks. David Herrmann suggest to also kill the DRIVER_USE_MTRR flag since it's now unused, which spurred me to do a bit a better audit of the affected drivers. David helped a lot in that.

At least nouveau seemed to work here, but it doesn't use AGP > or drm_bufs, I guess. Cool, thanks a lot for stitching together the list of drivers to look at. So for real KMS drivers it's the drives responsibility to add an mtrr if it needs one. nouvea, radeon, mgag200, i915 and vmwgfx do that already. Somehow the savage driver also ends up doing that, I have no idea why. Note that gma500 as a pure KMS driver doesn't need MTRR setup since the platforms that it supports all support PAT. So no MTRRs needed to get wc iomappings. The mtrr support in the drm core is all for legacy mappings of garts, framebuffers and registers. All legacy drivers set the USE_MTRR flag, so we're good there. All in all I think we can really just ditch this /endquote v2: Also kill DRIVER_USE_MTRR as suggested by David Herrmann v3: Rebase on top of David Herrmann's agp setup/cleanup changes.
