From b24bf8b8ba53834590be94d990e3305e4fd914ae Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Tue, 19 Sep 2023 17:56:16 -0400 Subject: [PATCH] drm/nouveau/disp: release outputs post-modeset Prior to this commit, KMS would call release() prior to modeset, and the second supervisor interrupt would update SOR routing if needed. Now, KMS will call release() post-modeset and update routing immediately. - preparation for GSP-RM Signed-off-by: Ben Skeggs Reviewed-by: Lyude Paul Acked-by: Danilo Krummrich Signed-off-by: Lyude Paul Link: https://patchwork.freedesktop.org/patch/msgid/20230919220442.202488-22-lyude@redhat.com --- drivers/gpu/drm/nouveau/dispnv50/disp.c | 18 ++++++++---------- .../gpu/drm/nouveau/nvkm/engine/disp/outp.c | 1 + .../gpu/drm/nouveau/nvkm/engine/disp/uoutp.c | 2 ++ 3 files changed, 11 insertions(+), 10 deletions(-) diff --git a/drivers/gpu/drm/nouveau/dispnv50/disp.c b/drivers/gpu/drm/nouveau/dispnv50/disp.c index ab048cf25d86..50a0ff304291 100644 --- a/drivers/gpu/drm/nouveau/dispnv50/disp.c +++ b/drivers/gpu/drm/nouveau/dispnv50/disp.c @@ -477,7 +477,6 @@ nv50_dac_atomic_disable(struct drm_encoder *encoder, struct drm_atomic_state *st core->func->dac->ctrl(core, nv_encoder->outp.or.id, ctrl, NULL); nv_encoder->crtc = NULL; - nvif_outp_release(&nv_encoder->outp); } static void @@ -1300,6 +1299,11 @@ nv50_mstm_cleanup(struct drm_atomic_state *state, } } + if (mstm->disabled) { + nvif_outp_release(&mstm->outp->outp); + mstm->disabled = false; + } + mstm->modified = false; } @@ -1334,12 +1338,6 @@ nv50_mstm_prepare(struct drm_atomic_state *state, nv50_msto_prepare(state, mst_state, &mstm->mgr, msto); } } - - if (mstm->disabled) { - if (!mstm->links) - nvif_outp_release(&mstm->outp->outp); - mstm->disabled = false; - } } static struct drm_connector * @@ -1582,7 +1580,6 @@ nv50_sor_atomic_disable(struct drm_encoder *encoder, struct drm_atomic_state *st nv_encoder->update(nv_encoder, nv_crtc->index, NULL, 0, 0); nv50_audio_disable(encoder, nv_crtc); - nvif_outp_release(&nv_encoder->outp); nv_encoder->crtc = NULL; } @@ -1827,7 +1824,6 @@ nv50_pior_atomic_disable(struct drm_encoder *encoder, struct drm_atomic_state *s core->func->pior->ctrl(core, nv_encoder->outp.or.id, ctrl, NULL); nv_encoder->crtc = NULL; - nvif_outp_release(&nv_encoder->outp); } static void @@ -1990,8 +1986,10 @@ nv50_disp_atomic_commit_core(struct drm_atomic_state *state, u32 *interlock) nv_encoder->conn, NULL, NULL); outp->enabled = outp->disabled = false; } else { - if (outp->disabled) + if (outp->disabled) { + nvif_outp_release(&nv_encoder->outp); outp->disabled = false; + } } } } diff --git a/drivers/gpu/drm/nouveau/nvkm/engine/disp/outp.c b/drivers/gpu/drm/nouveau/nvkm/engine/disp/outp.c index b288ea6658da..20a013f1bbba 100644 --- a/drivers/gpu/drm/nouveau/nvkm/engine/disp/outp.c +++ b/drivers/gpu/drm/nouveau/nvkm/engine/disp/outp.c @@ -238,6 +238,7 @@ void nvkm_outp_release(struct nvkm_outp *outp) { nvkm_outp_release_or(outp, NVKM_OUTP_USER); + nvkm_outp_route(outp->disp); } void diff --git a/drivers/gpu/drm/nouveau/nvkm/engine/disp/uoutp.c b/drivers/gpu/drm/nouveau/nvkm/engine/disp/uoutp.c index ffd174091454..40cbb4ddc037 100644 --- a/drivers/gpu/drm/nouveau/nvkm/engine/disp/uoutp.c +++ b/drivers/gpu/drm/nouveau/nvkm/engine/disp/uoutp.c @@ -188,6 +188,8 @@ nvkm_uoutp_mthd_release(struct nvkm_outp *outp, void *argv, u32 argc) if (argc != sizeof(args->vn)) return -ENOSYS; + if (!outp->ior) + return -EINVAL; nvkm_outp_release(outp); return 0; -- 2.25.1
