| Summary | r300g: Kernel rejected CS in Wine d3d multisample test |

When running Wine's d3d8 and d3d9 tests in r300g an invalid command stream is sent to the kernel: [ 916.508352] [drm:radeon_cs_packet_parse] *ERROR* Unknown packet type 1 at 2451 ! [ 916.508358] [drm:radeon_cs_ioctl] *ERROR* Invalid command stream ! [ 916.508902] [drm:radeon_cs_packet_parse] *ERROR* Unknown packet type 1 at 69 ! [ 916.508905] [drm:radeon_cs_ioctl] *ERROR* Invalid command stream ! The user space driver notices the error and writes a message to stderr. The test that triggered the invalid command subsequently fails. The failing line in the tests is http://source.winehq.org/git/wine.git/blob/f75d1b0c2f77d8c85f7c2a9bcc3545f14e271a86:/dlls/d3d8/tests/visual.c#l3704 . The test performs a copy from a multisampled color buffer to system memory. Wined3d first resolves the multisampled renderbuffer to a non-multisampled texture and calls glGetTexImage. Interestingly it is the glGetTexImage step that fails. The texture has format GL_BGRA, type GL_UNSIGNED_INT_8_8_8_8_REV and internal format GL_SRGB8_ALPHA8. We call glGetTexImage in plenty of places in this configuration, and this is the only case where this fails. I'll try to pin this down a bit further. The bug can be reproduced by running make visual.ok in dlls/d3d8/tests in a Wine build tree.
