2013-05-02drm: proc: Use minor->index to label things, not PDE->nameDavid Howells1-2/+1
Use minor->index to label things, not the name field from the proc_dir_entry of the /proc/dwm/<minor>/ directory. Also, use "%u" not "%d" to render the value and use a 12-byte buffer in which to render the integer, not a 16-byte buffer. The longest string an unsigned int can give you is 10 chars (4294967295) plus a NUL, so round up to 12 as the stack is likely to be 4- or 8-byte aligned.

2013-05-01drm/prime: keep a reference from the handle to exported dma-buf (v6)Dave Airlie1-3/+2
Currently we have a problem with this: 1. i915: create gem object 2. i915: export gem object to prime 3. radeon: import gem object 4. close prime fd 5. radeon: unref object 6. i915: unref object i915 has an imported object reference in its file priv, that isn't cleaned up properly until fd close. The reference gets added at step 2, but at step 6 we don't have enough info to clean it up. The solution is to take a reference on the dma-buf when we export it, and drop the reference when the gem handle goes away. So when we export a dma_buf from a gem object, we keep track of it with the handle, we take a reference to the dma_buf. When we close the handle (i.e. userspace is finished with the buffer), we drop the reference to the dma_buf, and it gets collected. This patch isn't meant to fix any other problem or bikesheds, and it doesn't fix any races with other scenarios. v1.1: move export symbol line back up. v2: okay I had to do a bit more, as the first patch showed a leak on one of my tests, that I found using the dma-buf debugfs support, the problem case is exporting a buffer twice with the same handle, we'd add another export handle for it unnecessarily, however we now fail if we try to export the same object with a different gem handle, however I'm not sure if that is a case I want to support, and I've gotten the code to WARN_ON if we hit something like that. v2.1: rebase this patch, write better commit msg. v3: cleanup error handling, track import vs export in linked list, these two patches were separate previously, but seem to work better like this. v4: danvet is correct, this code is no longer useful, since the buffer better exist, so remove it. v5: always take a reference to the dma buf object, import or export. (Imre Deak contributed this originally) v6: square the circle, remove import vs export tracking now that there is no difference Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: stable@vger.kernel.org Signed-off-by: Dave Airlie <airlied@redhat.com>
2013-04-30drm: Kill user_modes list and the associated ioctlsVille Syrjälä1-15/+0
There is no way to use modes added to the user_modes list. We never look at the contents of said list in the kernel, and the only operations userspace can do are attach and detach. So the only "benefit" of this interface is wasting kernel memory. Fortunately it seems no real user space application ever used these ioctls. So just kill them. Also remove the prototypes for the non-existing drm_mode_addmode_ioctl() and drm_mode_rmmode_ioctl() functions. v2: Use drm_noop instead of completely removing the ioctls Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

Core parts acked by Andrew Morton. - A bit of backlight code cleanup from Jani. - Fixed ilk gpu reset (Jesse). - Reduced color range handling fixes for VLV (Ville). The big item here is though the introduction of pipe_config to properly pre-compute the desired modeset state before touching the hw. Together with some very basic support to read out the current config from the hw and compare the state with the sw tracking. This is all prep work for more reliable fastboot, atomic modesets and other cool features. Stuff converted to the new world includes: - Most simple pipe attributes (reduce color range, pixel multiplier). - Pipe bpp/dither handling. - Some convenience flags like ->has_pch_encoder to simplify the code flow. - (Almost) DP clock handling, had to be reverted since part of a prep patch was lost in rebasing ...

For 3.10 I have a bunch of fixes queued up and I plan to send them all out at the end of this week. I need to shuffle patches in my -next queue a bit so that we don't but feature-y stuff in there, too. The main thing I'd like to sneak in is Egbert's hpd irq storm handling, which should be pretty low-risk since all the infrastructure work has landed already. I also have the oops fix pending, but that only mustered review before the w/e and giving how hairy that part of our modeset code is, I want to give it some more testing before forwarding.

git://people.freedesktop.org/~danvet/drm-intel into drm-next So here's my promised pile of fixes for 3.9. I've dropped the core prep patches for vt-switchless suspend/resume as discussed on irc. Highlights: - Fix dmar on g4x. Not really gfx related, but I'm fed up with getting blamed for dmar crapouts. - Disable wc ptes updates on ilk when dmar is enabled (Chris). So again, dmar, but this time gfx related :( - Reduced range support for hsw, using the pipe CSC (Ville). - Fixup pll limits for gen3/4 (Patrick Jakobsson). The sdvo patch is already confirmed to fix 2 bug reports, so added cc: stable on that one. - Regression fix for 8bit fb console (Ville). - Preserve lane reversal bits on DDI/FDI ports (Damien). - Page flip vs. gpu hang fixes (Ville). Unfortuntely not quite all of them, need to decide what to do with the currently still in-flight ones. - Panel fitter regression fix from Mika Kuoppala (was accidentally left on on some pipes with the new modset code since 3.7). This also improves the modeset sequence and might help a few other unrelated issues with lvds. - Write backlight regs even harder ... another installement in our eternal fight against the BIOS and backlights. - Fixup lid notifier vs. suspend/resume races (Zhang Rui). Prep work for new ACPI stuff, but closing the race itself seems worthwile on its own. - A few other small fixes and tiny cleanups all over. Lots of the patches are cc: stable since I've stalled on a few not-so-important fixes for 3.8 due to the grumpy noise Linus made. * 'drm-intel-fixes' of git://people.freedesktop.org/~danvet/drm-intel: (33 commits) intel/iommu: force writebuffer-flush quirk on Gen 4 Chipsets drm/i915: Disable WC PTE updates to w/a buggy IOMMU on ILK drm/i915: Implement pipe CSC based limited range RGB output drm/i915: inverted brightness quirk for Acer Aspire 4736Z drm/i915: Print the hw context status is debugfs drm/i915: Use HAS_L3_GPU_CACHE in i915_gem_l3_remap drm/i915: Fix PIPE_CONTROL DW/QW write through global GTT on IVB+ drm/i915: Set i9xx sdvo clock limits according to specifications drm/i915: Set i9xx lvds clock limits according to specifications drm/i915: Preserve the DDI link reversal configuration drm/i915: Preserve the FDI line reversal override bit on CPT drm/i915: add missing \n to UTS_RELEASE in the error_state drm: Use C8 instead of RGB332 when determining the format from depth/bpp drm: Fill depth/bits_per_pixel for C8 format drm/i915: don't clflush gem objects in stolen memory drm/i915: Don't wait for page flips if there was GPU reset drm/i915: Kill obj->pending_flip drm/i915: Fix a typo in a intel_modeset_stage_output_state() comment drm/i915: remove bogus mutex_unlock from error-path drm/i915: Print the pipe control page GTT address ...

2013-02-15drm/i915: Fix gen2 mappable calculationsBen Widawsky1-1/+2
When I refactored the code initially, I forgot that gen2 uses a different bar for the CPU mappable aperture. The agp-less code knows nothing of generations less than 5, so we have to expand the gtt_probe function to include the mappable base and end.

2013-02-14drm/fb-helper: improve kerneldocDaniel Vetter1-0/+12
Now that the fbdev helper interface for drivers is trimmed down, update the kerneldoc for all the remaining exported functions. I've tried to beat the DocBook a bit by reordering the function references a bit into a more sensible ordering. But that didn't work out at all. Hence just extend the in-code DOC: section a bit. Also remove the LOCKING: sections - especially for the setup functions they're totally bogus. But that's not a documentation problem, but simply an artifact of the current rather hazardous locking around drm init and even more so around fbdev setup ... v2: Some further improvements: - Also add documentation for drm_fb_helper_single_add_all_connectors, Dave Airlie didn't want me to kill this one from the fb helper interface. - Update docs for drm_fb_helper_fill_var/fix - they should be used from the driver's ->fb_probe callback to setup the fbdev info structure. - Clarify what the ->fb_probe callback should all do - it needs to setup both the fbdev info and allocate the drm framebuffer used as backing storage. - Add basic documentaation for the drm_fb_helper_funcs driver callback vfunc. v3: Implement clarifications Laurent Pinchart suggested in his review. v4: Fix another mispelling Laurent spotted.

Not called by anyone, and really, shouldn't be. Drivers are supposed either drm_fb_helper_initial_config or drm_fb_helper_hotplug_event.

2013-02-14drm/fb-helper: kill drm_fb_helper_restoreDaniel Vetter1-1/+0
It's only used internally for the sysrq and panic handlers provided by the drm fb helper implementation. Hence just inline it, kill the export and remove the confusing kerneldoc. Driver's are supposed to call drm_fb_helper_restore_fbdev_mode on lastclose. Note that locking is totally fubar - the sysrq case doesn't take any locks at all. The panic handler probably shouldn't take any locks since it'll only make things worse. Otoh it's probably better to switch things over to the atomic modeset callbacks (and disable the panic handler for those drivers which don't implement it). But that's both better done in separate patches. Reviewed-by: Rob Clark <robdclark@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2013-02-14drm: review locking for drm_fb_helper_restore_fbdev_modeDaniel Vetter1-0/+1
... it's required. Fix up exynos and the cma helper, and add a corresponding WARN_ON to drm_fb_helper_restore_fbdev_mode. Note that tegra calls the fbdev cma helper restore function also from it's driver-load callback. Which is a bit against current practice, since usually the call is only from ->lastclose, and initial setup is done by drm_fb_helper_initial_config. Also add the relevant drm DocBook entry. v2: Add promised WARN to restore_fbdev_mode. Reviewed-by: Rob Clark <robdclark@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2013-02-08drm: add prime helpersAaron Plattner1-0/+12
Instead of reimplementing all of the dma_buf functionality in every driver, create helpers drm_prime_import and drm_prime_export that implement them in terms of new, lower-level hook functions: gem_prime_pin: callback when a buffer is created, used to pin buffers into GTT gem_prime_get_sg_table: convert a drm_gem_object to an sg_table for export gem_prime_import_sg_table: convert an sg_table into a drm_gem_object gem_prime_vmap, gem_prime_vunmap: map and unmap an object These hooks are optional; drivers can opt in by using drm_gem_prime_import and drm_gem_prime_export as the .gem_prime_import and .gem_prime_export fields of struct drm_driver. v2: - Drop .begin_cpu_access. None of the drivers this code replaces implemented it. Having it here was a leftover from when I was trying to include i915 in this rework. - Use mutex_lock instead of mutex_lock_interruptible, as these three drivers did. This patch series shouldn't change that behavior. - Rename helpers to gem_prime_get_sg_table and gem_prime_import_sg_table. Rename struct sg_table* variables to 'sgt' for clarity. - Update drm.tmpl for these new hooks. v3: - Pass the vaddr down to the driver. This lets drivers that just call vunmap on the pointer avoid having to store the pointer in their GEM private structures. - Move documentation into a /** DOC */ comment in drm_prime.c and include it in drm.tmpl with a !P line. I tried to use !F lines to include documentation of the individual functions from drmP.h, but the docproc / kernel-doc scripts barf on that file, so hopefully this is good enough for now. - apply refcount fix from commit be8a42ae60addd8b6092535c11b42d099d6470ec ("drm/prime: drop reference on imported dma-buf come from gem") Signed-off-by: Aaron Plattner <aplattner@nvidia.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: David Airlie <airlied@linux.ie> Signed-off-by: Dave Airlie <airlied@redhat.com>

2013-01-21Merge branch 'drm-kms-locking' of ↵Dave Airlie3-1/+44
git://people.freedesktop.org/~danvet/drm-intel into drm-next The aim of this locking rework is that ioctls which a compositor should be might call for every frame (set_cursor, page_flip, addfb, rmfb and getfb/create_handle) should not be able to block on kms background activities like output detection. And since each EDID read takes about 25ms (in the best case), that always means we'll drop at least one frame. The solution is to add per-crtc locking for these ioctls, and restrict background activities to only use the global lock. Change-the-world type of events (modeset, dpms, ...) need to grab all locks. Two tricky parts arose in the conversion: - A lot of current code assumes that a kms fb object can't disappear while holding the global lock, since the current code serializes fb destruction with it. Hence proper lifetime management using the already created refcounting for fbs need to be instantiated for all ioctls and interfaces/users. - The rmfb ioctl removes the to-be-deleted fb from all active users. But unconditionally taking the global kms lock to do so introduces an unacceptable potential stall point. And obviously changing the userspace abi isn't on the table, either. Hence this conversion opportunistically checks whether the rmfb ioctl holds the very last reference, which guarantees that the fb isn't in active use on any crtc or plane (thanks to the conversion to the new lifetime rules using proper refcounting). Only if this is not the case will the code go through the slowpath and grab all modeset locks. Sane compositors will never hit this path and so avoid the stall, but userspace relying on these semantics will also not break. All these cases are exercised by the newly added subtests for the i-g-t kms_flip, tested on a machine where a full detect cycle takes around 100 ms. It works, and no frames are dropped any more with these patches applied. kms_flip also contains a special case to exercise the above-describe rmfb slowpath. * 'drm-kms-locking' of git://people.freedesktop.org/~danvet/drm-intel: (335 commits) drm/fb_helper: check whether fbcon is bound drm/doc: updates for new framebuffer lifetime rules drm: don't hold crtc mutexes for connector ->detect callbacks drm: only grab the crtc lock for pageflips drm: optimize drm_framebuffer_remove drm/vmwgfx: add proper framebuffer refcounting drm/i915: dump refcount into framebuffer debugfs file drm: refcounting for crtc framebuffers drm: refcounting for sprite framebuffers drm: fb refcounting for dirtyfb_ioctl drm: don't take modeset locks in getfb ioctl drm: push modeset_lock_all into ->fb_create driver callbacks drm: nest modeset locks within fpriv->fbs_lock drm: reference framebuffers which are on the idr drm: revamp framebuffer cleanup interfaces drm: create drm_framebuffer_lookup drm: revamp locking around fb creation/destruction drm: only take the crtc lock for ->cursor_move drm: only take the crtc lock for ->cursor_set drm: add per-crtc locks ...
