* loader_dri3: Handle mismatched depth 30 formats for Prime renderoffload.Mario Kleiner2018-08-012-1/+83
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Detect if the display (X-Server) gpu and Prime renderoffload gpu prefer different channel ordering for color depth 30 formats ([X/A]BGR2101010 vs. [X/A]RGB2101010) and perform format conversion during the blitImage() detiling op from tiled backbuffer -> linear buffer. For this we need to find the visual (= red channel mask) for the X-Drawable used to display on the server gpu. We use the same proven logic for finding that visual as in commit "egl/x11: Handle both depth 30 formats for eglCreateImage()". This is mostly to allow "NVidia Optimus" at depth 30, as Intel/AMD gpu's prefer xRGB2101010 ordering, whereas NVidia gpu's prefer xBGR2101010 ordering, so we can offload to nouveau without getting funky colors. Tested on Intel single gpu, NVidia single gpu, Intel + NVidia prime offload with DRI3/Present. Note: An unintended but pleasant surprise of this patch is that it also seems to make the modesetting-ddx of server 1.20.0 work at depth 30 on nouveau, at least with unredirected "classic" X rendering, and with redirected desktop compositing under XRender accel, and with OpenGL compositing under GLX. Only X11 compositing via OpenGL + EGL still gives funky colors. modesetting-ddx + glamor are not yet ready to deal with nouveau's ABGR2101010 format, and treat it as ARGB2101010, also exposing X-visuals with ARGB2101010 style channel masks. Seems somehow this triggers the logic in this patch on modesetting-ddx + depth 30 + DRI3 buffer sharing and does the "wrong" channel swizzling that then cancels out the "wrong" swizzling of glamor and we end up with the proper pixel formatting in the scanout buffer :). This so far tested on a NVA5 Tesla card under KDE5 Plasma as shipping with Ubuntu 16.04.4 LTS.

* dri3: For 1.2, use root window instead of pixmap drawableOlivier Fourdan2018-07-312-3/+10
| | | | | | | | | | | | | | | | | | | get_supported_modifiers() and pixmap_from_buffers() requests both expect a window as drawable, passing a pixmap will fail as the Xserver will fail to match the given drawable to a window. That leads to dri3_alloc_render_buffer() to return NULL and breaks rendering when using GLX_DOUBLEBUFFER on pixmaps. Query the root window of the pixmap on first init, and use the root window instead of the pixmap drawable for get_supported_modifiers() and pixmap_from_buffers().

This resulted in hangs with the Xorg modesetting driver as of xserver 1.20 (older versions and other drivers ignored the upper 32 bits of the target MSC, which is why this wasn't noticed earlier).

* loader: Add support for platform and host1x bussesThierry Reding2018-03-021-0/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ARM SoCs usually have their DRM/KMS devices on the platform bus, so add support for this bus in order to allow use of the DRI_PRIME environment variable with those devices. While at it, also support the host1x bus, which is effectively the same but uses an additional layer in the bus hierarchy. Note that it isn't enough to support the bus that has the rendering GPU because the loader code will also try to construct an ID path tag for a scanout-only device if it is the default that is being opened. The ID path tag for a device can be obtained by running udevadm info on the device node, as shown in this example on NVIDIA Tegra: $ udevadm info /dev/dri/card0 | grep ID_PATH_TAG E: ID_PATH_TAG=platform-50000000_host1x The corresponding OF_FULLNAME property, from which the ID_PATH_TAG is constructed, can be found in the sysfs "uevent" attribute for the card0 device's parent: $ grep OF_FULLNAME /sys/devices/platform/50000000.host1x/drm/uevent OF_FULLNAME=/host1x@50000000 Similarily, /dev/dri/card1 corresponds to the GPU: $ udevadm info /dev/dri/card1 | grep ID_PATH_TAG E: ID_PATH_TAG=platform-57000000_gpu and: $ grep OF_FULLNAME /sys/devices/platform/57000000.gpu/uevent OF_FULLNAME=/gpu@57000000 Changes in v2: - avoid confusing pre-increment in strdup() - add examples of tags to commit message Reviewed-by: Eric Engestrom <[email protected]> Reviewed-by: Emil Velikov <[email protected]> Signed-off-by: Thierry Reding <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | We were using a sequence counter value to wait for a specific NotifyMSC event. However, we can receive events from other clients as well, which may already be using higher sequence numbers than us. In that case, we could stop processing after an event from another client, which could have been received significantly earlier. This would have multiple undesirable effects: * The computed MSC and UST values would be lower than they should be * We could leave a growing number of NotifyMSC events from ourselves and other clients in XCB's special event queue I ran into this with Firefox and Thunderbird, whose VSync threads both seem to use the same window. The result was sluggish screen updates and growing memory consumption in one of them. Fix this by checking the XCB sequence number and MSC value of NotifyMSC events, instead of using our own sequence number. v2: * Use the Present event ID for the sequence parameter of the PresentNotifyMSC request, as another safeguard against processing events from other clients * Rebase on drawable mutex changes Reviewed-by: Nicolai Hähnle <[email protected]> # v1
* loader/dri3: Avoid freeing renderbuffers in useThomas Hellstrom2018-01-121-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | Upon reception of an event that lowered the number of active back buffers, the code would immediately try to free all back buffers with an id equal to or higher than the new number of active back buffers. However, that could lead to an active or to-be-active back buffer being freed, since the old number of back buffers was used when obtaining an idle back buffer for use. This lead to crashes when lowering the number of active back buffers by transitioning from page-flipping to non-page-flipping presents. Fix this by computing the number of active back buffers only when trying to obtain a new back buffer.

* loader/dri3: Improve dri3 thread-safetyThomas Hellstrom2017-11-132-18/+69
| | | | | | | | | | | | | | | | | | | | | | | | | It turned out that with recent changes that call into dri3 from glFinish(), it appears like different thread end up waiting for X events simultaneously, causing deadlocks since they steal events from eachoter and update the dri3 counters behind eachothers backs. This patch intends to improve on that. It allows at most one thread at a time to wait on events for a single drawable. If another thread intends to do the same, it's put to sleep until the first thread finishes waiting, and then it rechecks counters and optionally retries the waiting. Threads that poll for X events never pulls X events off the event queue if there are other threads waiting for events on that drawable. Counters in the dri3 drawable structure are protected by a mutex. Finally, the mutex we introduce is never held while waiting for the X server to avoid unnecessary stalls. This does not make dri3 drawables completely thread-safe but at least it's a first step.

* loader_dri3: Support GLX_SWAP_COPY_OMLThomas Hellstrom2017-08-172-1/+10
| | | | | | | | Support the GLX_SWAP_COPY_OML method. When this method is requested, we use the same swapbuffer code path as EGL_BUFFER_PRESERVED. Signed-off-by: Thomas Hellstrom <[email protected]> Reviewed-by: Michel Dänzer <[email protected]>
* loader_dri3: Honor the request to preserve back buffer contentThomas Hellstrom2017-08-172-3/+52
| | | | | | | | | | | | | | | | | | | | EGL uses the force_copy parameter to loader_dri3_swap_buffers_msc() to indicate that it wants to preserve back buffer contents across a buffer swap. While the loader then turns off server-side page-flipping there's nothing to guarantee that a new backbuffer isn't chosen when EGL starts to render again, and that buffer's content is of course undefined. So rework the functionality: If the client supports local blits, allow server-side page flipping and when a new back is grabbed, if needed, blit the old back's content to the new back. If the client doesn't support local blits, disallow server-side page-flipping to avoid a client deadlock and then, when grabbing a new back buffer, sleep until the old back is idle, which may take a substantial time depending on swap interval.
