git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next ASoC: Updates for v4.2 The big thing this release has been Liam's addition of topology support to the core. We've also seen quite a bit of driver work and the continuation of Lars' refactoring for component support. - Support for loading ASoC topology maps from firmware, intended to be used to allow self-describing DSP firmware images to be built which can map controls added by the DSP to userspace without the kernel needing to know about individual DSP firmwares. - Lots of refactoring to avoid direct access to snd_soc_codec where it's not needed supporting future refactoring. - Big refactoring and cleanup serieses for the Wolfson ADSP and TI TAS2552 drivers. - Support for TI TAS571x power amplifiers. - Support for Qualcomm APQ8016 and ZTE ZX296702 SoCs. - Support for x86 systems with RT5650 and Qualcomm Storm.

git://anongit.freedesktop.org/drm-intel into drm-next One more round of drm-misc, again mostly atomic. Big thing is the userspace blob code from Daniel Stone, with support for the mode_id blob now added to the atomic ioctl. Finally we can do atomic modesets! Note that the atomic ioctl is still behind the module knob since the weston patches aren't quite ready yet imo - they lack TEST_ONLY support, which is a fairly crucial bit of the atomic api. But besides that I think it's all good to go. That's also why we didn't bother to hide the new blob ioctls behind the knob, that part won't need to change. And if weston patches get in shape in time we could throw the "atomic by default patch" on top for 4.2. * tag 'topic/drm-misc-2015-05-27' of git://anongit.freedesktop.org/drm-intel: drm: Fix off-by-one in vblank hardware counter wraparound handling drm/atomic: fix out of bounds read in for_each_*_in_state helpers drm/atomic: Add MODE_ID property drm/atomic: Add current-mode blob to CRTC state drm: Add drm_atomic_set_mode_for_crtc drm: check for garbage in unused addfb2 fields drm: Retain reference to blob properties in lookup drm/mode: Add user blob-creation ioctl drm: Return error value from blob creation drm: Allow creating blob properties without copy drm/mode: Unstatic kernel-userspace mode conversion drm/mode: Validate modes inside drm_crtc_convert_umode drm/crtc_helper: Replace open-coded CRTC state helpers drm: kerneldoc fixes for blob properties drm/DocBook: Add more drm_bridge documentation drm: bridge: Allow daisy chaining of bridges drm/atomic: add all affected planes in drm_atomic_helper_check_modeset drm/atomic: add drm_atomic_add_affected_planes drm/atomic: add commit_planes_on_crtc helper
2015-06-03Add virtio gpu driver.Dave Airlie
This patch adds a kms driver for the virtio gpu. The xorg modesetting driver can handle the device just fine, the framebuffer for fbcon is there too. Qemu patches for the host side are under review currently. The pci version of the device comes in two variants: with and without vga compatibility. The former has a extra memory bar for the vga framebuffer, the later is a pure virtio device. The only concern for this driver is that in the virtio-vga case we have to kick out the firmware framebuffer. Initial revision has only 2d support, 3d (virgl) support requires some more work on the qemu side and will be added later.

2015-05-21drm: bridge: Allow daisy chaining of bridgesArchit Taneja
Allow drm_bridge objects to link to each other in order to form an encoder chain. The requirement for creating a chain of bridges comes because the MSM drm driver uses up its encoder and bridge objects for blocks within the SoC itself. There isn't anything left to use if the SoC display output is connected to an external encoder IC. Having an additional bridge connected to the existing bridge helps here. In general, it is possible for platforms to have multiple devices between the encoder and the connector/panel that require some sort of configuration. We create drm bridge helper functions corresponding to each op in 'drm_bridge_funcs'. These helpers call the corresponding 'drm_bridge_funcs' op for the entire chain of bridges. These helpers are used internally by drm_atomic_helper.c and drm_crtc_helper.c. The drm_bridge_enable/pre_enable helpers execute enable/pre_enable ops of the bridge closet to the encoder, and proceed until the last bridge in the chain is enabled. The same holds for drm_bridge_mode_set/mode_fixup helpers. The drm_bridge_disable/post_disable helpers disable the last bridge in the chain first, and proceed until the first bridge in the chain is disabled. drm_bridge_attach() remains the same. As before, the driver calling this function should make sure it has set the links correctly. The order in which the bridges are connected to each other determines the order in which the calls are made. One requirement is that every bridge in the chain should point the parent encoder object. This is required since bridge drivers expect a valid encoder pointer in drm_bridge. For example, consider a chain where an encoder's output is connected to bridge1, and bridge1's output is connected to bridge2: /* Like before, attach bridge to an encoder */ bridge1->encoder = encoder; ret = drm_bridge_attach(dev, bridge1); .. /* * set the first bridge's 'next' bridge to bridge2, set its encoder * as bridge1's encoder */ bridge1->next = bridge2 bridge2->encoder = bridge1->encoder; ret = drm_bridge_attach(dev, bridge2); ... ... This method of bridge chaining isn't intrusive and existing drivers that use drm_bridge will behave the same way as before. The bridge helpers also cleans up the atomic and crtc helper files a bit.

2015-05-08drm: Add edid_corrupt flag for Displayport Link CTS Previte
Displayport compliance test requires that a source device be capable of detecting a corrupt EDID. The test specification states that the sink device sets up the EDID with an invalid checksum. To do this, the sink sets up an invalid EDID header, expecting the source device to generate the checksum and compare it to the value stored in the last byte of the block data. Unfortunately, the DRM EDID reading and parsing functions are actually too good in this case; the header is fixed before the checksum is computed and thus the test never sees the invalid checksum. This results in a failure to pass the compliance test. To correct this issue, when the EDID code detects that the header is invalid, a flag is set to indicate that the EDID is corrupted. In this case, it sets edid_corrupt flag and continues with its fix-up code. This flag is also set in the case of a more seriously damaged header (fixup score less than the threshold). For consistency, the edid_corrupt flag is also set when the checksum is invalid as well. V2: - Removed the static bool global - Added a bool to the drm_connector struct to reaplce the static one for holding the status of raw edid header corruption detection - Modified the function signature of the is_valid function to take an additional parameter to store the corruption detected value - Fixed the other callers of the above is_valid function V3: - Updated the commit message to be more clear about what and why this patch does what it does. - Added comment in code to clarify the operations there - Removed compliance variable and check_link_status update; those have been moved to a later patch - Removed variable assignment from the bottom of the test handler V4: - Removed i915 tag from subject line as the patch is not i915-specific V5: - Moved code causing a compilation error to this patch where the variable is actually declared - Maintained blank lines / spacing so as to not contaminate the patch V6: - Removed extra debug messages - Added documentation to for the added parameter on drm_edid_block_valid - Fixed more whitespace issues in check_link_status - Added a clear of the header_corrupt flag to the end of the test handler in intel_dp.c - Changed the usage of the new function prototype in several places to use NULL where it is not needed by compliance testing V7: - Updated to account for long_pulse flag propagation V8: - Removed clearing of header_corrupt flag from the test handler in intel_dp.c - Added clearing of header_corrupt flag in the drm_edid_block_valid function V9: - Renamed header_corrupt flag to edid_corrupt to more accurately reflect its value and purpose - Updated commit message V10: - Updated for versioning and patch swizzle - Revised the title to more accurately reflect the nature and contents of the patch - Fixed formatting/whitespace problems - Added set flag when computed checksum is invalid Signed-off-by: Todd Previte <tprevite@gmail.com> Cc: dri-devel@lists.freedesktop.org Acked-by: Dave Airlie <airlied@redhat.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Paulo Zanoni <paulo.r.zanoni@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2015-05-04drm/vblank: Fixup and document timestamp update/read barriersDaniel Vetter
This was a bit too much cargo-culted, so lets make it solid: - vblank->count doesn't need to be an atomic, writes are always done under the protection of dev->vblank_time_lock. Switch to an unsigned long instead and update comments. Note that atomic_read is just a normal read of a volatile variable, so no need to audit all the read-side access specifically. - The barriers for the vblank counter seqlock weren't complete: The read-side was missing the first barrier between the counter read and the timestamp read, it only had a barrier between the ts and the counter read. We need both. - Barriers weren't properly documented. Since barriers only work if you have them on boths sides of the transaction it's prudent to reference where the other side is. To avoid duplicating the write-side comment 3 times extract a little store_vblank() helper. In that helper also assert that we do indeed hold dev->vblank_time_lock, since in some cases the lock is acquired a few functions up in the callchain. Spotted while reviewing a patch from Chris Wilson to add a fastpath to the vblank_wait ioctl. v2: Add comment to better explain how store_vblank works, suggested by Chris. v3: Peter noticed that as-is the 2nd smp_wmb is redundant with the implicit barrier in the spin_unlock. But that can only be proven by auditing all callers and my point in extracting this little helper was to localize all the locking into just one place. Hence I think that additional optimization is too risky.

There's now also support for panels to provide display timings rather than fixed modes, which should allow panels to work with a larger number of display drivers.

git://anongit.freedesktop.org/tegra/linux into drm-next drm/tegra: Changes for v4.1-rc1 Perhaps the most noteworthy change in this set is the implementation of a hardware VBLANK counter using host1x syncpoints. The SOR registers can now be dumped via debugfs, which can be useful while debugging. The IOVA address space maintained by the driver can also be dumped via debugfs. Other than than, these changes are mostly cleanup work, such as making register names more consistent or removing unused code (that was left over after the atomic mode-setting conversion). There's also a fix for eDP that makes the driver cope with firmware that already initialized the display (such as the firmware on the Tegra-based Chromebooks). * tag 'drm/tegra/for-4.1-rc1' of git://anongit.freedesktop.org/tegra/linux: drm/tegra: sor: Reset during initialization drm/tegra: gem: Return 64-bit offset for mmap(2) drm/tegra: hdmi: Name register fields consistently drm/tegra: hdmi: Resets are synchronous drm/tegra: dc: Document tegra_dc_state_setup_clock() drm/tegra: dc: Remove unused callbacks drm/tegra: dc: Remove unused function drm/tegra: dc: Use base atomic state helpers drm/atomic: Add helpers for state-subclassing drivers drm/tegra: dc: Implement hardware VBLANK counter gpu: host1x: Export host1x_syncpt_read() drm/tegra: sor: Dump registers via debugfs drm/tegra: sor: Registers are 32-bit drm/tegra: Provide debugfs file for the IOVA space drm/tegra: dc: Check for valid parent clock

If kref_put_mutex returns true then the caller or the put function is responsible for unlocking the mutex. The usual pattern assumes that the free callback unlocks the mutex, but since that is shared with the locked variant we need to explicitly unlock here.

2015-04-02drm/panel: Add display timing supportPhilipp Zabel
Many panel data sheets, additionally to typical values, list allowed ranges for timings such as hsync/vsync lengths, porches, and the pixel clock rate. These can be stored in a struct display_timing, to be used by an encoder mode_fixup callback to clamp user provided timing values or to validate workarounds for clock source limitations. This patch adds a new drm_panel_funcs callback that returns the panel's available display_timing entries.

2015-04-02drm/atomic: Add helpers for state-subclassing driversThierry Reding
Drivers that subclass CRTC, plane or connector state need to carefully duplicate the code that the atomic helpers have. This is bound to cause breakage eventually because it requires auditing all drivers and update them when code is added to the helpers. In order to avoid that, implement new helpers that perform the required steps when copying and destroying state. These new helpers are exported so that state-subclassing drivers can use them. The default helpers are implemented using them as well, providing a single location that needs to be changed when adding to base atomic states.
