2013-12-12Enable throttling in SwapBuffersAxel Davy1-1/+13
flush_with_flags, when available, allows the driver to throttle. Using this suppress input lag issues that can be observed in heavy rendering situations on non-intel cards.

2013-12-12egl/wayland: Send commit after flushing the driver contextKristian Høgsberg1-2/+1
This typically won't make a difference, since we only send the requests at wl_display_flush() time. There might be a small race with another thread calling wl_display_flush() after our commit request, but before we flush the DRI driver. Moving the commit below the DRI driver flush call looks more natural and eliminates the small race.

2013-12-09egl/wayland: Damage INT32_MAX x INT32_MAX region for eglSwapBuffersKristian Høgsberg1-2/+2
If we're not using EGL_EXT_swap_buffers_with_damage, we have to damage the full extent. EGL operates on buffer coordinates, but wl_surface.damage takes surface coordinates. EGL doesn't know the buffer transformation (rotated or scaled) and can't post accurate damage in surface coordinates. The damage event however is clipped to the surface extents so we can just damage the maximum rectangle. In case of EGL_EXT_swap_buffers_with_damage, the application knows the buffer transform and is expected to pass in rectangles in surface space.

2013-10-15egl_dri2: Set NativeVisualID to the matching GBM config for the gbm platformKristian Høgsberg1-2/+21
The EGLConfig doesn't have the rgba masks, only the rgba sizes. To make sure a config is usable with a given GBM/KMS format, we need a way to make sure the formats really match.
2013-10-15egl_dri2: Remove depth argument from dri2_add_config()Kristian Høgsberg6-26/+14
All callers now use the more correct rgba mask mechanism for filtering out mathcing DRI configs. Even if depth and buffer size match, the color component layout can be different, or in case or ARGB8888 and ARGB2101010 the color components can even be different sizes. Since anything that the depth check would reject is also rejected by the rgba mask comparison, the depth parameter is redundant and not specific enough. We should probably have removed it when the rgba masks argument was introduced, but better late than never. Signed-off-by: Kristian Høgsberg <krh@bitplanet.net>
2013-10-15egl_dri2: Match X11 visuals using rgba masks instead of depthKristian Høgsberg1-1/+20
Matching on visual depth to buffer size makes 8 bpc RGBA look similar to 10 bit RGB with 2 bit alphs - both have buffer size 32. Instead, build the rgba masks from the visual data and use that for finding matching DRI configs. We need to keep the special case that allows us to match 24 bit visuals to DRI configs with buffer size 32. We do that by creating an alpha mask of "all the non-rgb bits" for 24 bit visuals and matching a second time with that. Signed-off-by: Kristian Høgsberg <krh@bitplanet.net>

Now that libEGL has been fixed to not leak all kinds of symbols, gbm links to its own copy of the libwayland-drm.a helper library. That means we can't rely on comparing the addresses of a static vtable symbol in that library to determine if a wl_buffer is a wl_drm_buffer.

libEGL was incorrectly exporting *all* symbols, public and private. This patch adds -fvisibility=hidden to libEGL's linker flags to ensure that only symbols annotated with __attribute__((visibility("default"))) get exported. Sanity-checked with libEGL's builtin DRI2 driver and the i965 DRI driver by running Piglit on X/EGL and by running weston-gears on Weston as an X client.

2013-07-31egl: Restore "bogus" DRI2 invalidate event code.Eric Anholt1-0/+14
I had removed it in commit 1e7776ca2bc59a6978d9b933d23852d47078dfa8 because it was obviously wrong -- why do we care whether the server is a version that emits events, if we're not watching for the server's events, anyway? And why would you only invalidate on a server that emits invalidate events, when the comment said to emit invalidates if the server *doesn't*? Only, I missed that we otherwise don't flag that our buffers might have changed at swap time at all, so the driver was only checking for new buffers when triggered by the Viewport hack. Of course you don't expect Viewport to be called after a swap. So, this is effectively a revert of the previous commit, except that I dropped the check for only emitting invalidates on a new server -- we *always* need to invalidate if we're doing a SwapBuffers.

The commit below exposed a bug in dri2_add_config. commit 3998f8c6b5da1a223926249755e54d8f701f81ab Author: Ralf Jung <post@ralfj.de> Date: Tue Apr 9 14:09:50 2013 +0200 egl/x11: Fix initialisation of swap_interval This little code snippet near the bottom of dri2_add_config, if (double_buffer) { ... conf->base.MinSwapInterval = dri2_dpy->min_swap_interval; conf->base.MaxSwapInterval = dri2_dpy->max_swap_interval; } it never did what it claimed to do. The assignment never changed the value of conf->base.MaxSwapInterval, because dri2_dpy->max_swap_interval was, until the above exposing commit, unitialized here. That is, conf->base.MaxSwapInterval was 0 before and after assignment. Ditto for the min swap interval. Above the troublesome code snippet, the call to _eglFilterArray rejects the config as unmatching if its swap interval bounds differ from the base config's. Before the exposing commit, at the call to _eglFilterArray, the swap interval bounds were always [0,0], and hence no config was rejected due to swap interval. After the exposing commit, _eglFilterArray incorrectly rejected some configs, which prevented dri2_egl_config::dri_double_config from getting set for the rejected config, which resulted in a NULL pointer getting passed into dri2CreateNewDrawable, and then segfault. The solution: set the swap interval bounds before _eglFilterArray.

This also resulted in no multisample visuals being advertised. How many ways could we lose? This patch inverts the problem... now you can't get the visual with alpha used by the compositor even if you want it.
