* glx: Create proper server dependency for GLX_EXT_create_context_es2_profileIan Romanick2015-04-151-11/+1
| | | | | | | | | | | | | | | | | | | | Previously GLX_EXT_create_context_es2_profile was marked as "direct only" so that it would not depend on server support. Since the extension required functions that are part of GLX_ARB_create_context_profile, support for the EXT was disabled if the ARB was not supported. This was complete rubbish. If the server supported the ARB but not the EXT, sending a request with GLX_CONTEXT_ES2_PROFILE_BIT_EXT would result in GLXBadProfileARB. Instead of the misguided hack, make GLX_EXT_create_context_es2_profile properly depend on server support by not marking it as "direct only."

* glx: Handle out-of-sequence swap completion events correctly. (v2)Mario Kleiner2015-03-171-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code for emitting INTEL_swap_events swap completion events needs to translate from 32-Bit sbc on the wire to 64-Bit sbc for the events and handle wraparound accordingly. It assumed that events would be sent by the server in the order their corresponding swap requests were emitted from the client, iow. sbc count should be always increasing. This was correct for DRI2. This is not always the case under the DRI3/Present backend, where the Present extension can execute presents and send out completion events in a different order than the submission order of the present requests, due to client code specifying targetMSC target vblank counts which are not strictly monotonically increasing. This confused the wraparound handling. This patch fixes the problem by handling 32-Bit wraparound in both directions. As long as successive swap completion events real 64-Bit sbc's don't differ by more than 2^30, this should be able to do the right thing. How this is supposed to work: awire->sbc contains the low 32-Bits of the true 64-Bit sbc of the current swap event, transmitted over the wire. glxDraw->lastEventSbc contains the low 32-Bits of the 64-Bit sbc of the most recently processed swap event. glxDraw->eventSbcWrap is a 64-Bit offset which tracks the upper 32-Bits of the current sbc. The final 64-Bit output sbc aevent->sbc is computed from the sum of awire->sbc and glxDraw->eventSbcWrap. Under DRI3/Present, swap completion events can be received slightly out of order due to non-monotic targetMsc specified by client code, e.g., present request submission: Submission sbc: 1 2 3 targetMsc: 10 11 9 Reception of completion events: Completion sbc: 3 1 2 The completion sequence 3, 1, 2 would confuse the old wraparound handling made for DRI2 as 1 < 3 --> Assumes a 32-Bit wraparound has happened when it hasn't. The client can queue multiple present requests, in the case of Mesa up to n requests for n-buffered rendering, e.g., n = 2-4 in the current Mesa GLX DRI3/Present implementation. In the case of direct Pixmap presents via xcb_present_pixmap() the number n is limited by the amount of memory available. We reasonably assume that the number of outstanding requests n is much less than 2 billion due to memory contraints and common sense. Therefore while the order of received sbc's can be a bit scrambled, successive 64-Bit sbc's won't deviate by much, a given sbc may be a few counts lower or higher than the previous received sbc. Therefore any large difference between the incoming awire->sbc and the last recorded glxDraw->lastEventSbc will be due to 32-Bit wraparound and we need to adapt glxDraw->eventSbcWrap accordingly to adjust the upper 32-Bits of the sbc. Two cases, correponding to the two if-statements in the patch: a) Previous sbc event was below the last 2^32 boundary, in the previous glxDraw->eventSbcWrap epoch, the new sbc event is in the next 2^32 epoch, therefore the low 32-Bit awire->sbc wrapped around to zero, or close to zero --> awire->sbc is apparently much lower than the glxDraw->lastEventSbc recorded for the previous epoch --> We need to increment glxDraw->eventSbcWrap by 2^32 to adjust the current epoch to be one higher than the previous one. --> Case a) also handles the old DRI2 behaviour. b) Previous sbc event was above closest 2^32 boundary, but now a late event from the previous 2^32 epoch arrives, with a true sbc that belongs to the previous 2^32 segment, so the awire->sbc of this late event has a high count close to 2^32, whereas glxDraw->lastEventSbc is closer to zero --> awire->sbc is much greater than glXDraw->lastEventSbc. --> We need to decrement glxDraw->eventSbcWrap by 2^32 to adjust the current epoch back to the previous lower epoch of this late completion event. We assume such a wraparound to a higher (a) epoch or lower (b) epoch has happened if awire->sbc and glxDraw->lastEventSbc differ by more than 2^30 counts, as such a difference can only happen on wraparound, or if somehow 2^30 present requests would be pending for a given drawable inside the server, which is rather unlikely. v2: Explain the reason for this patch and the new wraparound handling much more extensive in commit message, no code change wrt. initial version.

* glx/dri3: Don't fail on glXSwapBuffersMscOML(dpy, window, 0, 0, 0) (v2)Mario Kleiner2014-12-141-2/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | glXSwapBuffersMscOML() with target_msc=divisor=remainder=0 gets translated into target_msc=divisor=0 but remainder=1 by the mesa api. This is done for server DRI2 where there needs to be a way to tell the server-side DRI2ScheduleSwap implementation if a call to glXSwapBuffers() or glXSwapBuffersMscOML(dpy,window,0,0,0) was done. remainder = 1 was (ab)used as a flag to tell the server to select proper semantic. The DRI3/Present backend ignored this signalling, treated any target_msc=0 as glXSwapBuffers() request, and called xcb_present_pixmap with invalid divisor=0, remainder=1 combo. The present extension responded kindly to this with a BadValue error and dropped the request, but mesa's DRI3/Present backend doesn't check for error codes. From there on stuff went downhill quickly for the calling OpenGL client...

* glx/dri3: Track separate (ust, msc) for PresentPixmap vs. PresentNotifyMsc (v2)Mario Kleiner2014-12-142-5/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prevent calls to glXGetSyncValuesOML() and glXWaitForMscOML() from overwriting the (ust,msc) values of the last successfull swapbuffers call (PresentPixmapCompleteNotify event), as glXWaitForSbcOML() relies on those values corresponding to the most recent completed swap, not to whatever was last returned from the server. Problematic call sequence without this patch would have been, e.g., glXSwapBuffers() ... wait ... swap completes -> PresentPixmapComplete event -> (ust,msc) updated to reflect swap completion time and count. ... wait for at least 1 video refresh cycle/vblank increment. glXGetSyncValuesOML() -> PresentNotifyMsc event overwrites (ust,msc) of swap completion with (ust,msc) of most recent vblank glXWaitForSbcOML() -> Returns sbc of last completed swap but (ust,msc) of last completed vblank, not of last completed swap. -> Client is confused. Do this by tracking a separate set of (ust, msc) for the dri3_wait_for_msc() call than for the dri3_wait_for_sbc() call. This makes the glXWaitForSbcOML() call robust again and restores consistent behaviour with the DRI2 implementation. Fixes applications originally written and tested against DRI2 which also rely on this not regressing under DRI3/Present, e.g., Neuro-Science software like Psychtoolbox-3.

* glx/dri3: Use four buffers until X driver supports async flipsKeith Packard2014-09-302-2/+24

This means we've got a scanout buffer pinned as soon as we schedule a flip and so we need another buffer to keep from stalling. When vblank_mode=0, if there are only three buffers we do: current scanout buffer = 0 at MSC 0 Render frame 1 to buffer 1 PresentPixmap for buffer 1 at MSC 1 This is sitting down in the kernel waiting for vblank to become the next scanout buffer Render frame 2 to buffer 2 PresentPixmap for buffer 2 at MSC 1 This cannot be displayed at MSC 1 because the kernel doesn't have any way to replace buffer 1 as the pending scanout buffer. So, best case this will get displayed at MSC 2. Now we block after this, waiting for one of the three buffers to become idle. We can't use buffer 0 because it is the scanout buffer. We can't use buffer 1 because it's sitting in the kernel waiting to become the next scanout buffer and we can't use buffer 2 because that's the most recent frame which will become the next scanout buffer if the application doesn't manage to generate another complete frame by MSC 2. With four buffers, we get: current scanout buffer = 0 at MSC 0 Render frame 1 to buffer 1 PresentPixmap for buffer 1 at MSC 1 This is sitting down in the kernel waiting for vblank to become the next scanout buffer Render frame 2 to buffer 2 PresentPixmap for buffer 2 at MSC 1 This cannot be displayed at MSC 1 because the kernel doesn't have any way to replace buffer 1 as the pending scanout buffer. So, best case this will get displayed at MSC 2. The X server will queue this swap until buffer 1 becomes the scanout buffer. Render frame 3 to buffer 3 PresentPixmap for buffer 3 at MSC 1 As soon as the X server sees this, it will replace the pending buffer 2 swap with this swap and release buffer 2 back to the application Render frame 4 to buffer 2 PresentPixmap for buffer 2 at MSC 1 Now we're in a steady state, flipping between buffer 2 and 3 waiting for one of them to be queued to the kernel. ... current scanout buffer = 1 at MSC 1 Now buffer 0 is free and (e.g.) buffer 2 is queued in the kernel to be the scanout buffer at MSC 2 Render frames, flipping between buffer 0 and 3 When the system can replace a queued buffer, and we update Present to take advantage of that, we can use three buffers and get: current scanout buffer = 0 at MSC 0 Render frame 1 to buffer 1 PresentPixmap for buffer 1 at MSC 1 This is sitting waiting for vblank to become the next scanout buffer Render frame 2 to buffer 2 PresentPixmap for buffer 2 at MSC 1 Queue this for display at MSC 1 1. There are three possible results: 1) We're still before MSC 1. Buffer 1 is released, buffer 2 is queued waiting for MSC 1. 2) We're now after MSC 1. Buffer 0 was released at MSC 1. Buffer 1 is the current scanout buffer. a) If the user asked for a tearing update, we swap scanout from buffer 1 to buffer 2 and release buffer 1. b) If the user asked for non-tearing update, we queue buffer 2 for the MSC 2. In all three cases, we have a buffer released (call it 'n'), ready to receive the next frame. Render frame 3 to buffer n PresentPixmap for buffer n If we're still before MSC 1, then we'll ask to present at MSC 1. Otherwise, we'll ask to present at MSC 2. Present already does this if the driver offers async flips, however it does this by waiting for the right vblank event and sending an async flip right at that point. I've hacked the intel driver to offer this, but I get tearing at the top of the screen. I think this is because flips are always done from within the ring, and so the latency between the vblank event and the async flip happening can cause tearing at the top of the screen. That's why I'm keying the need for the extra buffer on the lack of 2D driver support for async flips.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The differences with DRI2 GPU offloading are: a) There's no logic for GPU offloading needed in the Xserver b) for DRI2, the card would render to a back buffer, and the content would be copied to the front buffer (the same buffers everytime). Here we can potentially use several back buffers and copy to buffers with no tiling to share with X. We send them with the Present extension. That means than the DRI2 solution is forced to have tearings with GPU offloading. In the ideal scenario, this DRI3 solution doesn't have this problem. However without dma-buf fences, a race can appear (if the card is slow and the rendering hasn't finished before the server card reads the buffer), and then old content is displayed. If a user hits this, he should probably revert to the DRI2 solution (LIBGL_DRI3_DISABLE). Users with cards fast enough seem to not hit this in practice (I have an Amd hd 7730m, and I don't hit this, except if I force a low dpm mode) c) for non-fullscreen apps, the DRI2 GPU offloading solution requires compositing. This DRI3 solution doesn't have this requirement. Rendering to a pixmap also works. d) There is no need to have a DDX loaded for the secondary card.

* glxext: Send the Drawable's ID in the GLX_BufferSwapComplete eventJasper St. Pierre2014-06-271-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | While the official INTEL_swap_event specification says that the drawable field should contain the GLXDrawable, not the Drawable, the existing DRI2 code in dri2.c that translates from DRI2_BufferSwapComplete sends out GLX_BufferSwapComplete with the Drawable's ID, so existing codebases like Clutter/Cogl rely on getting the Drawable. Match DRI2's error here and stuff the event with the X Drawable, not the GLX drawable. This fixes apps seeing wrong drawables through an indirect GLX context or with DRI3, which uses the GLX_BufferSwapComplete event directly on the wire instead of translates Present in mesa. At the same time, also modify the structure for the event to make sure that clients don't make the same mistake. This is not an API or ABI break, as GLXDrawable and Drawable are both typedefs for XID.

* glx: Don't crash on swap event for a Window (non-GLXWindow)Daniel Manjarres2014-06-201-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prior to GLX 1.3 there was the glxMakeCurrent() function that took a single drawable handle. The Drawable could be either a bare XID for a Window or an XID for a glxpixmap. GLX 1.3 added glxMakeContextCurrent that takes 2 handles: one for reading, one for writing. Nowadays the old glxMakeCurrent call is implemented as a call to glxMakeContextCurrent with the single handle duplicated. Because of this it is allowed to use a plain-old Window ID as an argument to glxMakeContextCurrent, although nobody really documents this sort of thing. The manpage for the NEW call specifies the arguments as GLXPixmaps, but the actual code accepts Window XIDs too, and handles them correctly. Similarly, the glxSelectEvents function can also take a bare Window XID. The "piglit" tests all use GLXWindows and/or GLXPixmaps. You never tested swap events with a bare Window XID. That is what my app was doing. The swap_events code worked with Window XIDs in mesa 7.x.y. The new code added in versions 8, 9, and 10 assumes that all buffer swap events have a GLXPixmap associated with them. Because of the historical quirks above, this is not true. Swap events for bare Window XIDs do NOT have a glxpixmap resulting in a segfault. Any app that uses the old school glxMakeCurrent call with a Window XID while trying to use swap_events will crash when the libs try to lookup the nonexistent GLXPixmap associated with the incoming swap event. I believe that the people who wrote the spec overlooked this, because the "sbc" field comes from the OML_sync extension that is defined in terms of glxpixmaps only. v2 (idr): Formatting changes.

* glx: Add an error message when a direct renderer's createScreen() routine failsJon TURNEY2014-06-184-4/+12
| | | | | | | | | | | | | | | because no matching fbConfigs or visuals could be found. Nearly all the error cases in *createScreen() issue an error message to diagnose the failure to initialize before branching to handle_error. The few remaining error cases which don't should probably do the same. (At the moment, it seems this can be triggered in drisw with an X server which reports definite values for MAX_PBUFFFER_(WIDTH|HEIGHT|SIZE), because those attributes are checked for an exact match against 0.)
