2015-07-22drm: Check locking in drm_for_each_connectorDaniel Vetter
Because of DP MST connectors can now be hotplugged and we must hold the right lock when walking the connector lists. Enforce this by checking the locking in our shiny new list walking macros. v2: Extract the locking check into a small static inline helper to help readability. This will be more important when we make the read list access rules more complicated in later patches. Inspired by comments from Chris. Unfortunately, due to header loops around the definition of struct drm_device the function interface is a bit funny. v3: Encoders aren't hotadded/removed. For each dp mst encoder we statically create one fake encoder per pipe so that we can support as many mst sinks as the hw can (Dave).

And roll them out across drm_* files. The point here isn't code prettification (it helps with that too) but that some of these lists aren't static any more.

I've only seen this once, and I failed to capture the lockdep backtrace, but I did some investigations. If we are calling into the MST layer from EDID probing, we have the mode_config mutex held, if during that EDID probing, the MST hub goes away, then we can get a deadlock where the connector destruction function in the driver tries to retake the mode config mutex. This offloads connector destruction to a workqueue, and avoid the subsequenct lock ordering issue.

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.

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.

2015-05-18drm/atomic: Allow drivers to subclass drm_atomic_state, v3Maarten Lankhorst
Drivers may need to store the state of shared resources, such as PLLs or FIFO space, into the atomic state. Allow this by making it possible to subclass drm_atomic_state. Changes since v1: - Change member names for functions to atomic_state_(alloc,clear) - Change __drm_atomic_state_new to drm_atomic_state_init - Allow free function to be overridden too, in case extra memory is allocated in alloc. Changes since v2: - Rename *_default_free to default_release, to make clear it doesn't free the state object itself.

2015-05-08drm: Add edid_corrupt flag for Displayport Link CTS 4.2.2.6Todd Previte
Displayport compliance test 4.2.2.6 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>
