| | | | | | | | | | | | | | If there is a break inside the else clause and this means we are breaking from a loop, the loop finalise will want to insert the LOOP_BREAK/CONTINUE instruction, however if we don't emit the else there is no where for these to end up, so they will end up in the wrong place.

* r600: add ARB_query_buffer_object supportDave Airlie2018-01-2910-31/+817
| | | | | | | | | | | | | | This uses a different shader than radeonsi, as we can't address non-256 aligned ssbos, which the radeonsi code does. This passes some extra offsets into the shader. It also contains a set of u64 instruction implementation that may or may not be complete (at least the u64div is definitely not something that works outside this use-case). If r600 grows 64-bit integers, it will use the GLSL lowering for divmod. Reviewed-by: Roland Scheidegger <[email protected]> Signed-off-by: Dave Airlie <[email protected]>

| | | | | | | | | | | | | | The normal ssa renumbering isn't sufficient for LDS queue access, this uses two stacks, one for the lds queue, and one for the lds r/w ordering.

| | | | | | | | | | | | | This tries to avoid an lds queue read getting scheduled separately from an lds ret read, the non-sb code uses the same style of hammer, this isn't foolproof. We can do better, but it's a bit tricky, as you have to scan ahead and either schedule more lds oq moves and more lds reads and that could lead to you running out of space anyways.

* r600: don't emit tes samplers/views when tes isn't activeRoland Scheidegger2018-01-102-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | Similar to const buffers. The driver must not emit any tes-related state if tes is disabled, since the hw slots are all shared by VS, therefore it would overwrite them (the mesa state tracker might not do this, but it would be perfectly legal to do so). Nevertheless I think the dirty state tracking logic in the driver is fundamentally flawed when tes is disabled/enabled, since it looks to me like the VS (and TES) state would not get reemitted to the correct slots (if it's not dirty anyway). Unless I'm missing something... Theoretically, the overwrite problem could be solved by using non-overlapping resource slots for TES and VS (since we're not even close to using half the resource slots), but it wouldn't work for constant buffers nor samplers, and for VS would still need to propagate changes to both LS and VS, so probably not a useful idea. Unfortunately there's zero coverage of this with piglit, since all tessellation shader tests are just shader_runner tests, which are unsuitable for testing any kind of state dependency tracking issues (so I can't even quickly hack something up to proove it and fix it...). TCS otoh is just fine - like GS it has its own hw slots. Tested-by: Konstantin Kharlamov <[email protected]> Reviewed-by: Dave Airlie <[email protected]>
* r600: increase number of UBOs to 15Roland Scheidegger2018-01-103-22/+37
| | | | | | | | | | | | | | | | | With the exception of the default tess levels only ever accessed by the default tcs shader, the LDS_INFO const buffer was only accessed by vtx instructions, and not through kcache. No idea why really, but use this to our advantage by not using a constant buffer slot for it. This just requires us to throw the default tess levels into the "normal" driver const buffer instead. Alternatively, could acesss those constants via vtx instructions too, but then we couldn't use a ordinary ureg prog accessing them as constants and would have to generate that directly when compiling the default tcs shader. (Another alternative would be to put all lds info into the ordinary driver const buffer, albeit we'd maybe need to increase the fixed size as it can't fit alongside the ucp since vs needs access to the lds info too.)

* r600: use GET_BUFFER_RESINFO vtx fetch on eg instead of setting up constsRoland Scheidegger2018-01-104-58/+50
| | | | | | | | | | | | | | | | | | | Contrary to what the comment said, this appears to work just fine on my rv770 (tested with piglit textureSize 140 fs/vs samplerBuffer). Dave Airlie confirmed it working on cayman too. I have no clue though if it's actually preferrable to use it (unfortunately we cannot get rid of the tex constants completely, as we still require them for cube map txq). Albeit filling in the format (1 channels or 4?) and the stuff related to mega- or mini-fetch (what the hell is this...) is just a guess based on other usage of vtx fetch instructions... v2: it really needs to be done through texture cache (I botched the testing because sb optimizations turned it automatically into tc, but can't rely on it and isn't happening on tes).

* r600: increase number of ubos by one to 14Roland Scheidegger2018-01-104-4/+9
| | | | | | | | | | | | | | | Ideally we'd support 16 (d3d11 requires 15, and mesa subtracts one for non-ubo constants), but that's kind of impossible (it would be only doable if either we'd somehow merge the mesa non-ubo constants with the driver constants, or only use the driver constants with vtx fetch instead of through the kcache mechanism - the latter probably wouldn't be too bad). For now just do as the comment already said, place the gs ring (not really a const buffer in any case) which is only ever referred to through vc fetch clauses at index 16. Throw in a couple asserts for good measure to make sure the hw limit isn't exceeded. Tested-by: Konstantin Kharlamov <[email protected]> Reviewed-by: Dave Airlie <[email protected]>

* r600: hack up num_render_backends on Juniper to 8Roland Scheidegger2018-01-101-2/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | Juniper really has a maximum of 4 RBEs (16 pixels). However, predication always locks up on my HD 5750, and through experiments it looks like if we're pretending it has a maximum of 8, with 4 disabled, it works correctly. My conclusion would be that there's a bug (likely firmware, not hw) which causes the predication logic to try to read 8 results out of the query buffer instead of just 4, and since of course noone ever writes the upper 4, the status bit is never set and hence it will wait for it forever. Ideally this would be fixed in firmware, but I'd guess chances of that happening are slim. This will double the size of (occlusion) query result buffers, write the status bit for the disabled rbs in these buffers, and will also add 8 results together instead of just 4 when reading them back. The latter is unnecessary, but it's probably not worth bothering - luckily num_render_backends isn't used outside of occlusion queries, so don't need separate value for the "real" maximum. Also print out the enabled_rb_mask if it changed from the pre-fixed value (which is already printed out), just in case there's some more problems with chips which have some rbs disabled... This fixes all the lockups with piglit nv_conditional_render tests on my HD 5750 (all pass). Reviewed-by: Dave Airlie <[email protected]>
* r600: fix enabled_rb_mask on eg/cmRoland Scheidegger2018-01-101-2/+9
| | | | | | | | | | | | | | | | | | | | | | For eg/cm, the r600_gb_backend_map will always be 0. This is a bug in the drm kernel driver, as it just just never fills the information in (it is now being fixed - the history shows it was being filled in when the query was brand new but got lost shortly thereafter with backend_map fixes). This causes r600_query_hw_prepare_buffer to write the "status bit" (just the highest bit of the occlusion query result) even for active rbes (all but the first). This doesn't make much sense, albeit I suppose it's mostly safe. According to the commit history, it's necessary to set these bits for inactive rbes since otherwise predication will lock up - presumably the hw just is waiting for the status bit to appear, which will never happen with inactive rbes. I'd guess potentially predication could be wrong (due to not waiting for the actual result if the status bit is already there) if this is set for active rbes. Discovered while trying to fix predication lockups on Juniper (needs another patch). Reviewed-by: Dave Airlie <[email protected]>

| | | | | | | | | | | | | | piglit doesn't care, but I'm quite confident that the size actually bound as range should be reported and not the base size of the resource (and some quick piglit test hacking confirms this). Also, the array in the constant buffer looks overallocated by a factor of 4. For eg, also decrease the size by another factor of 2 by using the same constant slot for both buffer size (required for txq for TBOs) and the number of layers for cube arrays, as these are mutually exclusive. Could of course use some more logic and only actually do this for the samplers/images/buffers where it's required rather than for all, but ah well... Reviewed-by: Dave Airlie <[email protected]>
