From fc0139d28339f58bcbb4946fea7608ecdaff93e7 Mon Sep 17 00:00:00 2001 From: Karol Herbst Date: Sat, 24 Nov 2018 20:00:00 +0100 Subject: [PATCH] nv50,nvc0: Fix gallium nine regression regarding sampler bindings The new approach is that samplers don't get unbound even if they won't be used in a draw and we should just leave them be as well. Fixes a regression in multiple windows games using gallium nine and nouveau. v2: adjust num_samplers to keep track of the highest sampler bound v3: rework how to set the new value of num_samplers Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=106577 Fixes: 4d6fab245eec3880e2a59424a579851f44857ce8 "cso: don't track the number of sampler states bound" Signed-off-by: Karol Herbst Reviewed-by: Ilia Mirkin --- src/gallium/drivers/nouveau/nv50/nv50_state.c | 14 ++++++-------- src/gallium/drivers/nouveau/nvc0/nvc0_state.c | 14 ++++++-------- 2 files changed, 12 insertions(+), 16 deletions(-) diff --git a/src/gallium/drivers/nouveau/nv50/nv50_state.c b/src/gallium/drivers/nouveau/nv50/nv50_state.c index fb4a259ce16..e1b2e20810a 100644 --- a/src/gallium/drivers/nouveau/nv50/nv50_state.c +++ b/src/gallium/drivers/nouveau/nv50/nv50_state.c @@ -600,25 +600,23 @@ static inline void nv50_stage_sampler_states_bind(struct nv50_context *nv50, int s, unsigned nr, void **hwcso) { + unsigned highest_found = 0; unsigned i; assert(nr <= PIPE_MAX_SAMPLERS); for (i = 0; i < nr; ++i) { struct nv50_tsc_entry *old = nv50->samplers[s][i]; + if (hwcso[i]) + highest_found = i; + nv50->samplers[s][i] = nv50_tsc_entry(hwcso[i]); if (old) nv50_screen_tsc_unlock(nv50->screen, old); } assert(nv50->num_samplers[s] <= PIPE_MAX_SAMPLERS); - for (; i < nv50->num_samplers[s]; ++i) { - if (nv50->samplers[s][i]) { - nv50_screen_tsc_unlock(nv50->screen, nv50->samplers[s][i]); - nv50->samplers[s][i] = NULL; - } - } - - nv50->num_samplers[s] = nr; + if (nr >= nv50->num_samplers[s]) + nv50->num_samplers[s] = highest_found + 1; nv50->dirty_3d |= NV50_NEW_3D_SAMPLERS; } diff --git a/src/gallium/drivers/nouveau/nvc0/nvc0_state.c b/src/gallium/drivers/nouveau/nvc0/nvc0_state.c index f2393cb27b5..9653de86fe9 100644 --- a/src/gallium/drivers/nouveau/nvc0/nvc0_state.c +++ b/src/gallium/drivers/nouveau/nvc0/nvc0_state.c @@ -464,11 +464,15 @@ nvc0_stage_sampler_states_bind(struct nvc0_context *nvc0, unsigned s, unsigned nr, void **hwcso) { + unsigned highest_found = 0; unsigned i; for (i = 0; i < nr; ++i) { struct nv50_tsc_entry *old = nvc0->samplers[s][i]; + if (hwcso[i]) + highest_found = i; + if (hwcso[i] == old) continue; nvc0->samplers_dirty[s] |= 1 << i; @@ -477,14 +481,8 @@ nvc0_stage_sampler_states_bind(struct nvc0_context *nvc0, if (old) nvc0_screen_tsc_unlock(nvc0->screen, old); } - for (; i < nvc0->num_samplers[s]; ++i) { - if (nvc0->samplers[s][i]) { - nvc0_screen_tsc_unlock(nvc0->screen, nvc0->samplers[s][i]); - nvc0->samplers[s][i] = NULL; - } - } - - nvc0->num_samplers[s] = nr; + if (nr >= nvc0->num_samplers[s]) + nvc0->num_samplers[s] = highest_found + 1; } static void -- 2.30.2
