Hartmann explained, we don't support GPGPU on NVIDIA hardware, neither with the binary driver because NVIDIA doesn't provide any libOpenCL.so for FreeBSD, nor with the FOSS driver because we don't have the kernel video driver. On the AMD front, GPGPU works with the open-source stack (libclc and Clover, Mesa's libOpenCL.so), but the Clover port isn't committed yet. We didn't have the time to polish it so far (only libclc is available in devel/libclc). Note that Clover is still a WIP. Here's a matrix of implemented and missing features: http://dri.freedesktop.org/wiki/GalliumCompute/ When I tried it with simple programs found on the Net, it worked. However, I couldn't use it with graphics/darktable: 1) Currently, the amount of memory reported by Clover is hard-coded 2) darktable expects features not implemented --=20 Jean-S=E9bastien P=E9dron --vjsi4w6wh9naHn8l6wglVWKeEIaCedMpG Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQJ8BAEBCgBmBQJUVgamXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXQ2NzA4N0ZEMUFFQUUwRTEyREJDNkE2RjAz OUU5OTc2MUE1RkQ5NENDAAoJEDnpl2Gl/ZTM7zgP/282OnNvLW94DuHcZ13LLeKx nhibffPFPPhp3v7EHeSJW7vzwY6euYnqZW7w90UvqEm9Mmi72ohdchcainpHr2qR KoWu40IgAbXPsm0nZGjm5kkpv5W84FaxRyepww9k8Bp5/8WQyXYMzlpSn4gpQHaB sfCGRzmOqi0awvktt1CaWKWUJmD8YMiV6erIoKsHXIvoWvB+OappzyW34JmL0M4q gAdZztyynn0C77dwDYdW8hT2aBtOpD5M+O1ejN43WozCvinI9bggPAMJ8Lgtm0Kg hQ+XwFfjG61fqtK4QTkar9SMeQU3ISAE5iQgQcB4YbaFReu5BXgHCkZ8Tr6o91zj EdgC1Zt+Q3A5i8hA88o+jOXPZqUt1cN8PZ/P3SLrkmvWoNt/Xd1VdK/qrSmPx8ce OEZOptElU1PYi/t63eHQj0C2+FrDDSWFPwFUavUEabeCzNGunXPR769XU7adfGxp iXjM3juvIT3DlFhogwlzPc6r8Zb/AJnJquYs82x2ixAk0cOgUXJWjzRDurYPwnWa pMO3Zdk5kNDJJYrUJEU/9u/b0IDBeFlsgBWBfhi0FZLLdMFcsFgbdU5/3saDmviu PTXD2YX1azCWZ0km5es7ADGJlkCw3wRR5/kPq5hBA3tmc13Syenbm3X53goCGjFp iSBHNX0qnvEdjV1PtHd6 =pH7o -----END PGP SIGNATURE----- --vjsi4w6wh9naHn8l6wglVWKeEIaCedMpG--
