* isl/formats: R8G8B8_UNORM_SRGB isn't supported on HSWJason Ekstrand2019-07-301-1/+5
| | | | | | | | | | On Haswell, the format works but it doesn't properly do an sRGB decode. It appears to act identically to R8G8B8_UNORM. Only Vulkan uses this format so this only affects Vulkan on HSW.

* intel/isl: Add bounds-checking assertions for the format_info tableJason Ekstrand2018-06-071-8/+16
| | | | | | | | | | | We follow the same convention as isl_format_get_layout in having two assertions to ensure that only valid formats are passed in. We also check against the array size of the table because some valid formats such as CCS formats will may be past the end of the table. This fixes some potential out-of-bounds array access even in valid cases. Cc: [email protected] Reviewed-by: Lionel Landwerlin <[email protected]>

* intel/isl: Allow CCS_E on 1010102 formatsJason Ekstrand2018-05-091-11/+0
| | | | | | | | On CNL and above, CCS_E supports 1010102 formats and R11G11B10F. We had shut them off during early enabling because blorp_copy couldn't handle them. Now it can handle 1010102 formats so we can turn them back on. Reviewed-by: Topi Pohjolainen <[email protected]>
* intel/isl: Add format conversion codeJason Ekstrand2018-05-091-0/+214
| | | | | | | | | | | | | | This adds helpers to ISL to convert an isl_color_value to and from binary data encoded with a given isl_format. The conversion is done using ISL's built-in format introspection so it's fairly slow as format conversions go but it should be fine for a single pixel value. In particular, we can use this to convert clear colors. As a side-effect, we now rely on the sRGB helpers in libmesautil so we need to tweak the build system a bit. All prior uses of src/util in ISL were header-only. Reviewed-by: Topi Pohjolainen <[email protected]>

| | | | | | | | | | | | Split out the device info so isl doesn't depend on intel/common. Now it will depend on the new intel/dev device info lib. This will allow the decoder in intel/common to use isl, allowing us to apply Ken's patch that removes the genxml duplication of surface formats.

* intel/isl: Remove 'inline' keywordsMatt Turner2017-08-291-1/+1
| | | | | | | | | | | | | | | | | | | Unless you have data, the compiler knows better than you whether a function should be inlined. Unlike all other cases in this series, the removal of the inline keyword from isl_format_has_channel_type actually changes the resulting binary with gcc-6.3.0: text data bss dec hex filename 7831116 346384 420648 8598148 833284 i965_dri.so before 7830716 346384 420648 8597748 8330f4 i965_dri.so after I think this is likely an improvement.

| | | | | | | | | | | | | | These formats are already allowed by the i965 GL driver, and the feature seems to work just fine. There are tests for multisampled rendering in piglit: tests/spec/ext_framebuffer_multisample which can be patched to try GL_RGBA16F/32F/16I/16UI/32I/32UI in addition to GL_RGBA/8I.

| | | | | | | | | | | | | The term "lossless compression" could potentially mean multisample color compression, single-sample color compression or HiZ because they are all lossless. The term CCS_E, however, has a very precise meaning; in ISL and is only used to refer to single-sample color compression. It's also much shorter which is nice.

* isl: fix VA64 support for double and dvecN vertex attributesSamuel Iglesias Gonsálvez2017-01-091-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | We use *64*_PASSTHRU formats to upload vertex attributes of 64 bits to avoid conversions. From the BDW PRM, Volume 2d, page 586 (VERTEX_ELEMENT_STATE): "When SourceElementFormat is set to one of the *64*_PASSTHRU formats, 64-bit components are stored in the URB without any conversion. In this case, vertex elements must be written as 128 or 256 bits, with VFCOMP_STORE_0 being used to pad the output as required. E.g., if R64_PASSTHRU is used to copy a 64-bit Red component into the URB, Component 1 must be specified as VFCOMP_STORE_0 (with Components 2,3 set to VFCOMP_NOSTORE) in order to output a 128-bit vertex element, or Components 1-3 must be specified as VFCOMP_STORE_0 in order to output a 256-bit vertex element. Likewise, use of R64G64B64_PASSTHRU requires Component 3 to be specified as VFCOMP_STORE_0 in order to output a 256-bit vertex element." v2,v3 (Jason): - Don't delete unused formats.

| | | | | | | | | | | | | HiZ buffers can be multisampled and, on Broadwell and earlier, simply using interleaved multisampling with a compression block size of 8x4 samples yields the correct HiZ surface size calculations. Unfortunately, choose_msaa_layout was rejecting multisampled HiZ buffers because of format checks. Now that we have a simple helper for determining if a format supports multisampling, that's an easy enough issue to fix.
