* mesa_glinterop: remove mesa_glinterop typedefsEmil Velikov2016-05-305-21/+21
| | | | | | | | | | | | | | | | As is there are two places that do the typedefs - dri_interface.h and this header. As we cannot include the former in here, just drop the typedefs and use the struct directly (as needed). This is required because typedef redefinition is C11 feature which is not supported on all the versions of GCC used to build mesa. v2: Kill the typedef alltogether, as per Marek.

* gallium/swrast: fix front buffer blitting. (v2)Dave Airlie2015-10-311-5/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So I've known this was broken before, cogl has a workaround for it from what I know, but with the gallium based swrast drivers BlitFramebuffer from back to front or vice-versa was pretty broken. The legacy swrast driver tracks when a front buffer is used and does the get/put images when it is mapped/unmapped, so this patch attempts to add the same functionality to the gallium drivers. It creates a new context interface to denote when a front buffer is being created, and passes a private pointer to it, this pointer is then used to decide on map/unmap if the contents should be updated from the real frontbuffer using get/put image. This is primarily to make gtk's gl code work, the only thing I've tested so far is the glarea test from https://github.com/ebassi/glarea-example.git v2: bump extension version, check extension version before calling get image.

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.
