2016-10-05drm/prime: Take a ref on the drm_dev when exporting a dma_bufChris Wilson1-0/+4
dma_buf may live a long time, longer than the last direct user of the driver. We already hold a reference to the owner module (that prevents the object code from disappearing), but there is no reference to the drm_dev - so the pointers to the driver backend themselves may vanish. v2: Resist temptation to fix the bug in armada_gem.c not setting the correct flags on the exported dma-buf (it should pass the flags through and not be arbitrarily setting O_RDWR). Use a common wrapper for exporting the dmabuf and acquiring the reference to the drm_device.

2016-10-05drm/prime: Pass the right module owner through to dma_buf_export()Chris Wilson1-1/+2
dma_buf_export() adds a reference to the owning module to the dmabuf (to prevent the driver from being unloaded whilst a third party still refers to the dmabuf). However, drm_gem_prime_export() was passing its own THIS_MODULE (i.e. drm.ko) rather than the driver. Extract the right owner from the device->fops instead. v2: Use C99 initializers to zero out unset elements of dma_buf_export_info v3: Extract the right module from dev->fops.

2016-10-04drm: Convert prime dma-buf <-> handle to rbtreeChris Wilson1-2/+3
Currently we use a linear walk to lookup a handle and return a dma-buf, and vice versa. A long overdue TODO task is to convert that to a hashtable. Since the initial implementation of dma-buf/prime, we now have resizeable hashtables we can use (and now a future task is to RCU enable the lookup!). However, this patch opts to use an rbtree instead to provide O(lgN) lookups (and insertion, deletion). rbtrees were chosen over using the RCU backed resizable hashtable to firstly avoid the reallocations (rbtrees can be embedded entirely within the parent struct) and to favour simpler code with predictable worst case behaviour. In simple testing, the difference between using the constant lookup and insertion of the rhashtable and the rbtree was less than 10% of the wall time (igt/benchmarks/prime_lookup) - both are dramatic improvements over the existing linear lists. v2: Favour rbtree over rhashtable Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=94631 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Sean Paul <seanpaul@chromium.org> Cc: David Herrmann <dh.herrmann@gmail.com> Reviewed-by: David Herrmann <dh.herrmann@gmail.com> Reviewed-by: Sean Paul <seanpaul@chromium.org> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/20160926204414.23222-1-chris@chris-wilson.co.uk

2016-09-19drm: drop obsolete drm_core.hDavid Herrmann1-34/+0
The drm_core.h header contains a set of constants meant to be used throughout DRM. However, as it turns out, they're each used just once and don't bring any benefit. They're also grossly mis-named and lack name-spacing. This patch inlines them, or moves them into drm_internal.h as appropriate: - CORE_AUTHOR and CORE_DESC are inlined into corresponding MODULE_*() macros. It's just confusing having to follow 2 pointers when trying to find the definition of these fields. Grep'ping for MODULE_AUTHOR() should reveal the full information, if there's no strong reason not to. - CORE_NAME, CORE_DATE, CORE_MAJOR, CORE_MINOR, and CORE_PATCHLEVEL are inlined into the sysfs 'version' attribute. They're stripped everywhere else (which is just some printk() statements). CORE_NAME just doesn't make *any* sense, as we hard-code it in many places, anyway. The other constants are outdated and just serve binary-compatibility purposes. Hence, inline them in 'version' sysfs attribute (we might even try dropping it..). - DRM_IF_MAJOR and DRM_IF_MINOR are moved into drm_internal.h as they're only used by the global ioctl handlers. Furthermore, versioning interfaces breaks backports and as such is deprecated, anyway. We just keep them for historic reasons. I doubt anyone will ever modify them again.

Patch 3d50d4dcb0 exposed the CPU address of DMA-allocated pages as returned by dma_alloc_coherent because Nouveau on Tegra needed it. This is not required anymore - as there were no other users for it, remove it and save some memory for everyone.

2016-09-07drm/i2c: tda998x: Register ASoC hdmi-codec and add audio DT bindingJyri Sarha1-2/+3
Register ASoC HDMI codec for audio functionality and adds device tree binding for audio configuration. With the registered HDMI codec the tda998x node can be used like a regular codec node in ASoC card configurations. HDMI audio info-frame and audio stream header is generated by the ASoC HDMI codec. The codec also applies constraints for available sample-rates based on Edid Like Data from the display. The device tree binding document has been updated [1]. Part of this patch has been inspired by Jean Francoise's "drm/i2c: tda998x: Add support of a DT graph of ports"-patch [2]. There may still be some identical lines left from the original patch and some of the ideas have come from there.

2016-09-05drm: extra printk() wrapper macrosDave Gordon1-6/+20
We had only DRM_INFO() and DRM_ERROR(), whereas the underlying printk() provides several other useful intermediate levels such as NOTICE and WARNING. So this patch fills out the set by providing both regular and once-only macros for each of the levels INFO, NOTICE, and WARNING, using a common underlying macro that does all the token-pasting. DRM_ERROR is unchanged, as it's not just a printk wrapper. v2: Fix whitespace, missing ## (Eric Engestrom) Signed-off-by: Dave Gordon <david.s.gordon@intel.com> Reviewed-by: Eric Engestrom <eric.engestrom@imgtec.com> Cc: dri-devel@lists.freedesktop.org Acked-by: Dave Airlie <airlied@redhat.com> Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
