Now that we have infoframes to report the pixel repeat flag, we can start using it. Fixes locking the 720x480i and 720x576i modes on my Dell 2408WFP. Like the 1920x1080i case, they don't fit properly on the screen, though. Signed-off-by:Eric Anholt <eric@anholt.net>

We really do need to be using the halved V fields. I had been confused by the code I was using as a reference because it stored halved vsync fields but not halved vdisplay, so it looked like I only needed to divide vdisplay by 2. This reverts part of Mario's timestamping fixes that prevented CRTC_HALVE_V from applying, and instead adjusts the timestamping code to not use the crtc field in that case. Fixes locking of 1920x1080x60i on my Dell 2408WFP. There are black bars on the top and bottom, but I suspect that might be an under/overscan flags problem as opposed to video timings.

On Pi0/1/2, we use an external GPIO line for hotplug detection, since the HDMI_HOTPLUG register isn't connected to anything. However, with the Pi3 the HPD GPIO line has moved off to a GPIO expander that will be tricky to get to (the firmware is constantly polling the expander using i2c0, so we'll need to coordinate with it). As a stop-gap, if we don't have a GPIO line, use an EDID probe to detect connection. Fixes HDMI display on the pi3. Signed-off-by: -

There's no point in enabling PSR when the panel doesn't support it. This also avoids a problem when PSR gets enabled when a CRTC is being disabled, because sometimes in that situation the DSP_HOLD_VALID_INTR interrupt on which we wait will never arrive. This was observed on RK3288 with a panel without PSR (veyron-jaq Chromebook). It's very easy to reproduce by running the kms_rmfb test in IGT a few times.

It's perfectly legal for the sink to support 12bpc only for some lower resolution modes, while the higher resolution modes can only be used with 8bpc. So let's take the sink's max TMDS clock into account before we go and decide that a particular mode can be used with 12bpc. Signed-off-by:

drm_edid_to_eld() is just mean to cook up the ELD for the audio driver, so having it parse non-audio related stuff seems just wrong, and potentially could lead to that information not being even filled out if the function doesn't even get called.

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=94631Signed-off-by:

Before commit a3257256 ("drm: Lobotomize set_busid nonsense for !pci drivers"), several DRM drivers for platform devices used to expose an explicit "drm_driver.set_busid" callback, invariably backed by drm_platform_set_busid(). Commit a3257256 removed drm_platform_set_busid(), along with the referring .set_busid field initializations. This was justified because interchangeable functionality had been implemented in drm_dev_alloc() / drm_dev_init(), which DRM_IOCTL_SET_VERSION would rely on going forward. However, commit a3257256 also removed drm_virtio_set_busid(), for which the same consolidation was not appropriate: this .set_busid callback had been implemented with drm_pci_set_busid(), and not drm_platform_set_busid(). The error regressed Xorg/xserver on QEMU's "virtio-vga" card; the drmGetBusid() function from libdrm would no longer return stable PCI identifiers like "pci:0000:00:02.0", but rather unstable platform ones like "virtio0".

The runqueue worker currently issues a get() when a new node is processed, and a put() once a node is completed. The corresponding suspend and resume calls currently only do clock gating, but with the upcoming introduction of IOMMU runpm also the corresponding IOMMU domain gets enabled (for get()) and disabled (for put()). This introduces performance regressions with we mitigate here. Switch PM runtime to autosuspend, such that clock gating and IOMMU control only happens when the engine is idle for a 'long' time.

While the engine works on a runqueue node it does memory access to the buffers associated with that node. Make sure that the engine is idle when g2d_close() and/or g2d_remove() are called, i.e. buffer associated with the process (for g2d_close()), or all buffers (for g2d_remove()) can be safely be unmapped. We have to take into account that the engine might be in an undefined state, i.e. it hangs and doesn't become idle. In this case, we issue a hardware reset to return the hardware and the driver context into a proper state. Signed-off-by:

This reverts commit b05984e2. The change, i.e. merging the sleep and runpm operations, produces a deadlock situation: (1) exynos_g2d_exec_ioctl() prepares a runqueue node and calls g2d_exec_runqueue() (2) g2d_exec_runqueue() calls g2d_dma_start() which gets runtime PM sync (3) runtime PM core calls g2d_runtime_resume() (4) g2d_runtime_resume() calls g2d_exec_runqueue(), which loops back to (2) Due to mutexes that are in place, a deadlock situation is created.
