From: Keith Whitwell Date: Thu, 7 Sep 2006 16:23:22 +0000 (+0000) Subject: Use lower alignments where possible. Also pad out allocated blocks to X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1456a0fff6a68dac046aaa57585eadf65ad66892;p=mesa.git Use lower alignments where possible. Also pad out allocated blocks to a multiple of alignment to avoid accumulating unusable free blocks. --- diff --git a/src/mesa/drivers/dri/i965/brw_state_pool.c b/src/mesa/drivers/dri/i965/brw_state_pool.c index 60565bf83cb..2b469638cff 100644 --- a/src/mesa/drivers/dri/i965/brw_state_pool.c +++ b/src/mesa/drivers/dri/i965/brw_state_pool.c @@ -95,7 +95,7 @@ static void brw_init_pool( struct brw_context *brw, pool->size = size; pool->brw = brw; - bmGenBuffers(&brw->intel, "pool", 1, &pool->buffer); + bmGenBuffers(&brw->intel, "pool", 1, &pool->buffer, 0); /* Also want to say not to wait on fences when data is presented */ diff --git a/src/mesa/drivers/dri/i965/brw_wm_state.c b/src/mesa/drivers/dri/i965/brw_wm_state.c index accf1243ec4..4707a709e77 100644 --- a/src/mesa/drivers/dri/i965/brw_wm_state.c +++ b/src/mesa/drivers/dri/i965/brw_wm_state.c @@ -79,7 +79,7 @@ static void upload_wm_unit(struct brw_context *brw ) */ if (!brw->wm.scratch_buffer) { - bmGenBuffers(intel, "wm scratch", 1, &brw->wm.scratch_buffer); + bmGenBuffers(intel, "wm scratch", 1, &brw->wm.scratch_buffer, 12); bmBufferSetInvalidateCB(intel, brw->wm.scratch_buffer, invalidate_scratch_cb, diff --git a/src/mesa/drivers/dri/i965/bufmgr.h b/src/mesa/drivers/dri/i965/bufmgr.h index 50fbcda50b5..63e1011a768 100644 --- a/src/mesa/drivers/dri/i965/bufmgr.h +++ b/src/mesa/drivers/dri/i965/bufmgr.h @@ -84,7 +84,8 @@ int bmInitPool( struct intel_context *, * understood, and drivers can just pass the calls through without too * much thunking. */ -void bmGenBuffers(struct intel_context *, const char *, unsigned n, struct buffer **buffers); +void bmGenBuffers(struct intel_context *, const char *, unsigned n, struct buffer **buffers, + int align ); void bmDeleteBuffers(struct intel_context *, unsigned n, struct buffer **buffers); diff --git a/src/mesa/drivers/dri/i965/bufmgr_fake.c b/src/mesa/drivers/dri/i965/bufmgr_fake.c index b9f1553c74d..1cb3f67b349 100644 --- a/src/mesa/drivers/dri/i965/bufmgr_fake.c +++ b/src/mesa/drivers/dri/i965/bufmgr_fake.c @@ -163,10 +163,16 @@ static GLboolean alloc_from_pool( struct intel_context *intel, struct bufmgr *bm = intel->bm; struct pool *pool = &bm->pool[pool_nr]; struct block *block = (struct block *)calloc(sizeof *block, 1); + GLuint sz, align = (1<alignment); + if (!block) return GL_FALSE; - block->mem = mmAllocMem(pool->heap, buf->size, buf->alignment, 0); + sz = (buf->size + align-1) & ~(align-1); + + block->mem = mmAllocMem(pool->heap, + sz, + buf->alignment, 0); if (!block->mem) { free(block); return GL_FALSE; @@ -621,14 +627,14 @@ int bmInitPool( struct intel_context *intel, return retval; } -static struct buffer *do_GenBuffer(struct intel_context *intel, const char *name) +static struct buffer *do_GenBuffer(struct intel_context *intel, const char *name, int align) { struct bufmgr *bm = intel->bm; struct buffer *buf = calloc(sizeof(*buf), 1); buf->id = ++bm->buf_nr; buf->name = name; - buf->alignment = 12; /* page-alignment to fit in with AGP swapping */ + buf->alignment = align ?
