From: Ben Skeggs <[email protected]> The kernel previously exposed incorrect classes for some of the chipsets that this code supports. It no longer does, but the older object ioctls have compatibility to avoid breaking userspace.
This needs to be fixed before switching over to the newer interfaces. Rather than hardcoding chipset->class like the rest of the driver does, this makes use of (new) sclass queries to determine what's available. v2. - update to use symbolic class identifier from <nvif/class.h> Signed-off-by: Ben Skeggs <[email protected]> --- src/gallium/drivers/nouveau/nv50/nv98_video.c | 57 ++++++++++++++++++++++++--- 1 file changed, 51 insertions(+), 6 deletions(-) diff --git a/src/gallium/drivers/nouveau/nv50/nv98_video.c b/src/gallium/drivers/nouveau/nv50/nv98_video.c index 20ea547..177a7e0 100644 --- a/src/gallium/drivers/nouveau/nv50/nv98_video.c +++ b/src/gallium/drivers/nouveau/nv50/nv98_video.c @@ -25,6 +25,8 @@ #include "util/u_sampler.h" #include "util/u_format.h" +#include <nvif/class.h> + static void nv98_decoder_decode_bitstream(struct pipe_video_codec *decoder, struct pipe_video_buffer *video_target, @@ -56,6 +58,28 @@ nv98_decoder_decode_bitstream(struct pipe_video_codec *decoder, nv98_decoder_ppp(dec, desc, target, comm_seq); } +static const struct nouveau_mclass +nv98_decoder_msvld[] = { + { G98_MSVLD, -1 }, + { IGT21A_MSVLD, -1 }, + { GT212_MSVLD, -1 }, + {} +}; + +static const struct nouveau_mclass +nv98_decoder_mspdec[] = { + { G98_MSPDEC, -1 }, + { GT212_MSPDEC, -1 }, + {} +}; + +static const struct nouveau_mclass +nv98_decoder_msppp[] = { + { G98_MSPPP, -1 }, + { GT212_MSPPP, -1 }, + {} +}; + struct pipe_video_codec * nv98_create_decoder(struct pipe_context *context, const struct pipe_video_codec *templ) @@ -103,12 +127,33 @@ nv98_create_decoder(struct pipe_context *context, } push = dec->pushbuf; - if (!ret) - ret = nouveau_object_new(dec->channel[0], 0x390b1, 0x85b1, NULL, 0, &dec->bsp); - if (!ret) - ret = nouveau_object_new(dec->channel[1], 0x190b2, 0x85b2, NULL, 0, &dec->vp); - if (!ret) - ret = nouveau_object_new(dec->channel[2], 0x290b3, 0x85b3, NULL, 0, &dec->ppp); + if (!ret) { + ret = nouveau_object_mclass(dec->channel[0], nv98_decoder_msvld); + if (ret >= 0) { + ret = nouveau_object_new(dec->channel[0], 0xbeef85b1, + nv98_decoder_msvld[ret].oclass, NULL, 0, + &dec->bsp); + } + } + + if (!ret) { + ret = nouveau_object_mclass(dec->channel[1], nv98_decoder_mspdec); + if (ret >= 0) { + ret = nouveau_object_new(dec->channel[1], 0xbeef85b2, + nv98_decoder_mspdec[ret].oclass, NULL, 0, + &dec->vp); + } + } + + if (!ret) { + ret = nouveau_object_mclass(dec->channel[2], nv98_decoder_msppp); + if (ret >= 0) { + ret = nouveau_object_new(dec->channel[2], 0xbeef85b3, + nv98_decoder_msppp[ret].oclass, NULL, 0, + &dec->ppp); + } + } + if (ret) goto fail; -- 2.6.4 _______________________________________________ Nouveau mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/nouveau
