Support for AMD Pitcairn and Tahiti processors

[santzi]

Hi,

This is very nice program. I have used this now about half year. I have AMD 7850 2GB (Pitcairn) graphic card and Debian 7.3.0, but I need to make changes to oclengine.c -file every time when I download a new repo and compiled it. I download this repo, because this support compressed mode.

I add these two lines to oclengine.c -file and then it works like charm: if (!strcmp(dvn, "Tahiti") || !strcmp(dvn, "Pitcairn")) quirks &= ~VG_OCL_AMD_BFI_INT;

I now there are plenty of people who has the same problem as me had, so this change might help Pitcairn and Tahiti processors users.

oclengine.c: case 0x1002: /* AMD/ATI / / * AMD's compiler works best with preprocesor unrolling. * Pragma unroll is unreliable with AMD's compiler and * seems to crash based on whether the gods were smiling * when Catalyst was last installed/upgraded. */ if (vg_ocl_device_gettype(vocp->voc_ocldid) & CL_DEVICE_TYPE_GPU) { quirks |= VG_OCL_EXPENSIVE_BRANCHES; quirks |= VG_OCL_DEEP_VLIW; dvn = vg_ocl_device_getstr(vocp->voc_ocldid, CL_DEVICE_EXTENSIONS); if (dvn && strstr(dvn, "cl_amd_media_ops")) quirks |= VG_OCL_AMD_BFI_INT;

        dvn = vg_ocl_device_getstr(vocp->voc_ocldid,
                       CL_DEVICE_NAME);
                    if (!strcmp(dvn, "Tahiti") || !strcmp(dvn, "Pitcairn"))
                            quirks &= ~VG_OCL_AMD_BFI_INT;

        if (!strcmp(dvn, "ATI RV710")) {
            quirks &= ~VG_OCL_OPTIMIZATIONS;
            quirks |= VG_OCL_NO_BINARIES;
        }
    }

br, Santzi
