From d99ec708afbb785ce05031661222b38c9447059f Mon Sep 17 00:00:00 2001 From: Marek Olšák Date: Mon, 28 Feb 2011 13:38:01 +0100 Subject: r300g: fix HiZ memory size computation and deciding when to use HiZ I removed the HiZ memory management, because the HiZ RAM is too small and I also did it in hope that HiZ will be enabled more often. This also sets aligned strides to HIZ_PITCH and ZMASK_PITCH. --- src/gallium/drivers/r300/r300_blit.c | 63 ++++++++++--------- src/gallium/drivers/r300/r300_context.c | 17 ++--- src/gallium/drivers/r300/r300_context.h | 26 ++++---- src/gallium/drivers/r300/r300_emit.c | 66 ++++---------------- src/gallium/drivers/r300/r300_hyperz.c | 69 ++------------------- src/gallium/drivers/r300/r300_hyperz.h | 35 ----------- src/gallium/drivers/r300/r300_state.c | 30 +++------ src/gallium/drivers/r300/r300_state_derived.c | 3 +- src/gallium/drivers/r300/r300_texture.c | 8 +-- src/gallium/drivers/r300/r300_texture_desc.c | 89 ++++++++++++++++++++------- 10 files changed, 148 insertions(+), 258 deletions(-) delete mode 100644 src/gallium/drivers/r300/r300_hyperz.h (limited to 'src/gallium/drivers/r300') diff --git a/src/gallium/drivers/r300/r300_blit.c b/src/gallium/drivers/r300/r300_blit.c index 4f86db3992..fd8ef444dc 100644 --- a/src/gallium/drivers/r300/r300_blit.c +++ b/src/gallium/drivers/r300/r300_blit.c @@ -22,7 +22,6 @@ #include "r300_context.h" #include "r300_emit.h" -#include "r300_hyperz.h" #include "r300_texture.h" #include "r300_winsys.h" @@ -117,6 +116,14 @@ static boolean r300_fast_zclear_allowed(struct r300_context *r300) return r300_resource(fb->zsbuf->texture)->tex.zmask_dwords[fb->zsbuf->u.tex.level]; } +static boolean r300_hiz_clear_allowed(struct r300_context *r300) +{ + struct pipe_framebuffer_state *fb = + (struct pipe_framebuffer_state*)r300->fb_state.state; + + return r300_resource(fb->zsbuf->texture)->tex.hiz_dwords[fb->zsbuf->u.tex.level]; +} + static uint32_t r300_depth_clear_value(enum pipe_format format, double depth, unsigned stencil) { @@ -190,8 +197,6 @@ static void r300_clear(struct pipe_context* pipe, (struct pipe_framebuffer_state*)r300->fb_state.state; struct r300_hyperz_state *hyperz = (struct r300_hyperz_state*)r300->hyperz_state.state; - struct r300_resource *zstex = - fb->zsbuf ? r300_resource(fb->zsbuf->texture) : NULL; uint32_t width = fb->width; uint32_t height = fb->height; boolean can_hyperz = r300->rws->get_value(r300->rws, R300_CAN_HYPERZ); @@ -200,20 +205,17 @@ static void r300_clear(struct pipe_context* pipe, /* Enable fast Z clear. * The zbuffer must be in micro-tiled mode, otherwise it locks up. */ if ((buffers & PIPE_CLEAR_DEPTHSTENCIL) && can_hyperz) { - hyperz_dcv = hyperz->zb_depthclearvalue = - r300_depth_clear_value(fb->zsbuf->format, depth, stencil); - if (r300_fast_zclear_allowed(r300)) { + hyperz_dcv = hyperz->zb_depthclearvalue = + r300_depth_clear_value(fb->zsbuf->format, depth, stencil); + r300_mark_atom_dirty(r300, &r300->zmask_clear); buffers &= ~PIPE_CLEAR_DEPTHSTENCIL; } - if (zstex->hiz_mem[fb->zsbuf->u.tex.level]) + if (r300_hiz_clear_allowed(r300)) { r300_mark_atom_dirty(r300, &r300->hiz_clear); - - /* XXX Change this to r300_mark_atom_dirty(r300, &r300->hyperz_state); - * once hiz offset is constant. */ - r300_mark_fb_state_dirty(r300, R300_CHANGED_HYPERZ_FLAG); + } } /* Enable CBZB clear. */ @@ -240,14 +242,14 @@ static void r300_clear(struct pipe_context* pipe, fb->nr_cbufs, buffers, rgba, depth, stencil); r300_blitter_end(r300); - } else if (r300->zmask_clear.dirty) { + } else if (r300->zmask_clear.dirty || r300->hiz_clear.dirty) { /* Just clear zmask and hiz now, this does not use the standard draw * procedure. */ unsigned dwords; /* Calculate zmask_clear and hiz_clear atom sizes. */ r300_update_hyperz_state(r300); - dwords = r300->zmask_clear.size + + dwords = (r300->zmask_clear.dirty ? r300->zmask_clear.size : 0) + (r300->hiz_clear.dirty ? r300->hiz_clear.size : 0) + r300_get_num_cs_end_dwords(r300); @@ -257,9 +259,11 @@ static void r300_clear(struct pipe_context* pipe, } /* Emit clear packets. */ - r300_emit_zmask_clear(r300, r300->zmask_clear.size, - r300->zmask_clear.state); - r300->zmask_clear.dirty = FALSE; + if (r300->zmask_clear.dirty) { + r300_emit_zmask_clear(r300, r300->zmask_clear.size, + r300->zmask_clear.state); + r300->zmask_clear.dirty = FALSE; + } if (r300->hiz_clear.dirty) { r300_emit_hiz_clear(r300, r300->hiz_clear.size, r300->hiz_clear.state); @@ -279,9 +283,8 @@ static void r300_clear(struct pipe_context* pipe, /* Enable fastfill and/or hiz. * * If we cleared zmask/hiz, it's in use now.
