2013-06-17drm: Drop all the stub gamma_get, gamma_set, load_lut functions from driversVille Syrjälä1-15/+0
Many of the drivers didn't implement palette/gamma handling, but were forced to provide stubs for the hooks to avoid drm_fb_helper from oopsing. Now that the hooks are optional, we can eliminate all the stubs.

2013-02-14drm/<drivers>: simplify ->fb_probe callbackDaniel Vetter1-19/+3
The fb helper lost its support for reallocating an fb completely, so no need to return special success values any more. Reviewed-by: Rob Clark <[email protected]> Signed-off-by: Daniel Vetter <[email protected]>
2013-02-14drm/fb-helper: don't disable everything in initial_configDaniel Vetter1-0/+4
This should be done in the drivers for two reasons: - it gets in the way of fastboot efforts - it links the fb helpers with the crtc helpers instead of going through the real interface vfuncs, forcing i915 to fake all the ->disable callbacks used by the crtc helper to avoid ugly Oopsen v2: Resolve conflicts since drivers still call drm_fb_helper_single_add_all_connectors.

There seems to be a bad interaction between gem/shmem and defio on top, I get list corruption on the page lru in the shmem code. Turn it off for now until we get some more digging done. Cc: [email protected] Signed-off-by: Dave Airlie <[email protected]>
2013-02-07drm/udl: make usage as a console saferDave Airlie1-4/+40
Okay you don't really want to use udl devices as your console, but if you are unlucky enough to do so, you run into a lot of schedule while atomic due to printk being called from all sorts of funky places. So check if we are in an atomic context, and queue the damage for later, the next printk should cause it to appear. This isn't ideal, but it is simple, and seems to work okay in my testing here. (dirty area idea came from xenfb) fixes a bunch of sleeping while atomic issues running fbcon on udl devices. Cc: [email protected] Signed-off-by: Dave Airlie <[email protected]>
2013-01-20drm: revamp framebuffer cleanup interfacesDaniel Vetter1-0/+1
We have two classes of framebuffer - Created by the driver (atm only for fbdev), and the driver holds onto the last reference count until destruction. - Created by userspace and associated with a given fd. These framebuffers will be reaped when their assoiciated fb is closed. Now these two cases are set up differently, the framebuffers are on different lists and hence destruction needs to clean up different things. Also, for userspace framebuffers we remove them from any current usage, whereas for internal framebuffers it is assumed that the driver has done this already. Long story short, we need two different ways to cleanup such drivers. Three functions are involved in total: - drm_framebuffer_remove: Convenience function which removes the fb from all active usage and then drops the passed-in reference. - drm_framebuffer_unregister_private: Will remove driver-private framebuffers from relevant lists and drop the corresponding references. Should be called for driver-private framebuffers before dropping the last reference (or like for a lot of the drivers where the fbdev is embedded someplace else, before doing the cleanup manually). - drm_framebuffer_cleanup: Final cleanup for both classes of fbs, should be called by the driver's ->destroy callback once the last reference is gone. This patch just rolls out the new interfaces and updates all drivers (by adding calls to drm_framebuffer_unregister_private at all the right places)- no functional changes yet. Follow-on patches will move drm core code around and update the lifetime management for framebuffers, so that we are no longer required to keep framebuffers alive by locking mode_config.mutex. I've also updated the kerneldoc already. vmwgfx seems to again be a bit special, at least I haven't figured out how the fbdev support in that driver works. It smells like it's external though. v2: The i915 driver creates another private framebuffer in the load-detect code. Adjust its cleanup code, too.

2013-01-20drm/<drivers>: Unified handling of unimplemented fb->create_handleDaniel Vetter1-1/+0
Some drivers don't have real ->create_handle callbacks. - cirrus/ast/mga200: Returns either 0 or -EINVAL. - udl: Didn't even bother with a callback, leading to a nice userspace-triggerable OOPS. - vmwgfx: This driver bothered with an implementation to return 0 as the handle (which is the canonical no-obj gem handle). All have in common that ->create_handle doesn't really make too much sense for them - that ioctl is used only for seamless fb takeover in the radeon/nouveau/i915 ddx drivers. So allow drivers to not implement this and return a consistent -ENODEV. Signed-off-by: Daniel Vetter <[email protected]>
2013-01-20drm/<drivers>: reorder framebuffer init sequenceDaniel Vetter1-1/+1
With more fine-grained locking we can no longer rely on the big mode_config lock to prevent concurrent access to mode resources like framebuffers. Instead a framebuffer becomes accessible to other threads as soon as it is added to the relevant lookup structures. Hence it needs to be fully set up by the time drivers call drm_framebuffer_init. This patch here is the drivers part of that reorg. Nothing really fancy going on safe for three special cases. - exynos needs to be careful to properly unref all handles. - nouveau gets a resource leak fixed for free: one of the error cases didn't cleanup the framebuffer, which is now moot since the framebuffer is only registered once it is fully set up. - vmwgfx requires a slight reordering of operations, I'm hoping I didn't break anything (but it's refcount management only, so should be safe). v2: Split out exynos, since it's a bit more hairy than expected. v3: Drop bogus cirrus hunk noticed by Richard Wilbur. v4: Split out vmwgfx since there's a small change in return values.

2012-11-02drm/udl: fix stride issues scanning out stride != width*bppDave Airlie1-5/+7
When buffer sharing with the i915 and using a 1680x1050 monitor, the i915 gives is a 6912 buffer for the 6720 width, the code doesn't render this properly as it uses one value to set the base address for reading from the vmap and for where to start on the device. This fixes it by calculating the values correctly for the device and for the pixmap. No idea how I haven't seen this before now. Cc: [email protected] Signed-off-by: Dave Airlie <[email protected]>
2012-10-09mm: kill vma flag VM_RESERVED and mm->reserved_vm counterKonstantin Khlebnikov1-1/+1
A long time ago, in v2.4, VM_RESERVED kept swapout process off VMA, currently it lost original meaning but still has some effects: | effect | alternative flags -+------------------------+--------------------------------------------- 1| account as reserved_vm | VM_IO 2| skip in core dump | VM_IO, VM_DONTDUMP 3| do not merge or expand | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP 4| do not mlock | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP This patch removes reserved_vm counter from mm_struct. Seems like nobody cares about it, it does not exported into userspace directly, it only reduces total_vm showed in proc. Thus VM_RESERVED can be replaced with VM_IO or pair VM_DONTEXPAND | VM_DONTDUMP. remap_pfn_range() and io_remap_pfn_range() set VM_IO|VM_DONTEXPAND|VM_DONTDUMP. remap_vmalloc_range() set VM_DONTEXPAND | VM_DONTDUMP.

Pull drm merge (part 1) from Dave Airlie: "So first of all my tree and uapi stuff has a conflict mess, its my fault as the nouveau stuff didn't hit -next as were trying to rebase regressions out of it before we merged. Highlights: - SH mobile modesetting driver and associated helpers - some DRM core documentation - i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write combined pte writing, ilk rc6 support, - nouveau: major driver rework into a hw core driver, makes features like SLI a lot saner to implement, - psb: add eDP/DP support for Cedarview - radeon: 2 layer page tables, async VM pte updates, better PLL selection for > 2 screens, better ACPI interactions The rest is general grab bag of fixes. So why part 1? well I have the exynos pull req which came in a bit late but was waiting for me to do something they shouldn't have and it looks fairly safe, and David Howells has some more header cleanups he'd like me to pull, that seem like a good idea, but I'd like to get this merge out of the way so -next dosen't get blocked."

Remove redundant DRM UAPI header #inclusions from drivers/gpu/. Remove redundant #inclusions of core DRM UAPI headers (drm.h, drm_mode.h and drm_sarea.h). They are now #included via drmP.h and drm_crtc.h via a preceding patch. Without this patch and the patch to make include the UAPI headers from the core headers, after the UAPI split, the DRM C sources cannot find these UAPI headers because the DRM code relies on specific -I flags to make #include "..." work on headers in include/drm/ - but that does not work after the UAPI split without adding more -I flags.

2012-03-15drm/udl: initial UDL driver (v4)Dave Airlie1-0/+611
This is an initial drm/kms driver for the displaylink devices. Supports fb_defio, supports KMS dumb interface supports 24bpp via conversion to 16bpp, hw can do this better. supports hot unplug using new drm core features. On an unplug, it disables connector polling, unplugs connectors from sysfs, unplugs fbdev layer (using Kay's API), drops all the USB device URBs, and call the drm core to unplug the device. This driver is based in large parts on udlfb.c so I've licensed it under GPLv2. Signed-off-by: Dave Airlie <[email protected]>
