From 0fdc5111b4e659de8258ae8f3eb8e33ef466beb3 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Fri, 17 Oct 2014 15:04:27 +0100 Subject: [PATCH] vc4: Add a little bit more packet parsing to make dump reading easier. Probably should have done this *before* staring at all those render lists today. --- src/gallium/drivers/vc4/vc4_cl_dump.c | 133 ++++++++++++++++++++++---- 1 file changed, 114 insertions(+), 19 deletions(-) diff --git a/src/gallium/drivers/vc4/vc4_cl_dump.c b/src/gallium/drivers/vc4/vc4_cl_dump.c index a55c04fc144..6c380219ce1 100644 --- a/src/gallium/drivers/vc4/vc4_cl_dump.c +++ b/src/gallium/drivers/vc4/vc4_cl_dump.c @@ -25,11 +25,101 @@ #include "util/macros.h" #include "vc4_context.h" -#define PACKET(name, size) [name] = { #name, size } +#define dump_VC4_PACKET_LINE_WIDTH dump_float +#define dump_VC4_PACKET_POINT_SIZE dump_float + +static void +dump_float(void *cl, uint32_t offset, uint32_t hw_offset) +{ + void *f = cl + offset; + + fprintf(stderr, "0x%08x 0x%08x: %f (0x%08x)\n", + offset, hw_offset, *(float *)f, *(uint32_t *)f); +} + +static void +dump_VC4_PACKET_BRANCH_TO_SUB_LIST(void *cl, uint32_t offset, uint32_t hw_offset) +{ + uint32_t *addr = cl + offset; + + fprintf(stderr, "0x%08x 0x%08x: addr 0x%08x\n", + offset, hw_offset, *addr); +} + +static void +dump_VC4_PACKET_FLAT_SHADE_FLAGS(void *cl, uint32_t offset, uint32_t hw_offset) +{ + uint32_t *bits = cl + offset; + + fprintf(stderr, "0x%08x 0x%08x: bits 0x%08x\n", + offset, hw_offset, *bits); +} + +static void +dump_VC4_PACKET_VIEWPORT_OFFSET(void *cl, uint32_t offset, uint32_t hw_offset) +{ + uint16_t *o = cl + offset; + + fprintf(stderr, "0x%08x 0x%08x: %f, %f (0x%04x, 0x%04x)\n", + offset, hw_offset, + o[0] / 16.0, o[1] / 16.0, + o[0], o[1]); +} + +static void +dump_VC4_PACKET_CLIPPER_XY_SCALING(void *cl, uint32_t offset, uint32_t hw_offset) +{ + uint32_t *scale = cl + offset; + + fprintf(stderr, "0x%08x 0x%08x: %f, %f (%f, %f, 0x%08x, 0x%08x)\n", + offset, hw_offset, + uif(scale[0]) / 16.0, uif(scale[1]) / 16.0, + uif(scale[0]), uif(scale[1]), + scale[0], scale[1]); +} + +static void +dump_VC4_PACKET_CLIPPER_Z_SCALING(void *cl, uint32_t offset, uint32_t hw_offset) +{ + uint32_t *translate = cl + offset; + uint32_t *scale = cl + offset + 8; + + fprintf(stderr, "0x%08x 0x%08x: %f, %f (0x%08x, 0x%08x)\n", + offset, hw_offset, + uif(translate[0]), uif(translate[1]), + translate[0], translate[1]); + + fprintf(stderr, "0x%08x 0x%08x: %f, %f (0x%08x, 0x%08x)\n", + offset + 8, hw_offset + 8, + uif(scale[0]), uif(scale[1]), + scale[0], scale[1]); +} + +static void +dump_VC4_PACKET_TILE_COORDINATES(void *cl, uint32_t offset, uint32_t hw_offset) +{ + uint8_t *tilecoords = cl + offset; + + fprintf(stderr, "0x%08x 0x%08x: %d, %d\n", + offset, hw_offset, tilecoords[0], tilecoords[1]); +} + +static void +dump_VC4_PACKET_GEM_HANDLES(void *cl, uint32_t offset, uint32_t hw_offset) +{ + uint32_t *handles = cl + offset; + + fprintf(stderr, "0x%08x 0x%08x: handle 0: %d, handle 1: %d\n", + offset, hw_offset, handles[0], handles[1]); +} + +#define PACKET_DUMP(name, size) [name] = { #name, size, dump_##name } +#define PACKET(name, size) [name] = { #name, size, NULL } static const struct packet_info { const char *name; uint8_t size; + void (*dump_func)(void *cl, uint32_t offset, uint32_t hw_offset); } packet_info[] = { PACKET(VC4_PACKET_HALT, 1), PACKET(VC4_PACKET_NOP, 1), @@ -41,7 +131,7 @@ static const struct packet_info { PACKET(VC4_PACKET_WAIT_ON_SEMAPHORE, 1), PACKET(VC4_PACKET_BRANCH, 5), - PACKET(VC4_PACKET_BRANCH_TO_SUB_LIST, 5), + PACKET_DUMP(VC4_PACKET_BRANCH_TO_SUB_LIST, 5), PACKET(VC4_PACKET_STORE_MS_TILE_BUFFER, 1), PACKET(VC4_PACKET_STORE_MS_TILE_BUFFER_AND_EOF, 1), @@ -63,23 +153,23 @@ static const struct packet_info { PACKET(VC4_PACKET_VG_SHADER_STATE, 5), PACKET(VC4_PACKET_CONFIGURATION_BITS, 4), - PACKET(VC4_PACKET_FLAT_SHADE_FLAGS, 5), - PACKET(VC4_PACKET_POINT_SIZE, 5), - PACKET(VC4_PACKET_LINE_WIDTH, 5), + PACKET_DUMP(VC4_PACKET_FLAT_SHADE_FLAGS, 5), + PACKET_DUMP(VC4_PACKET_POINT_SIZE, 5), + PACKET_DUMP(VC4_PACKET_LINE_WIDTH, 5), PACKET(VC4_PACKET_RHT_X_BOUNDARY, 3), PACKET(VC4_PACKET_DEPTH_OFFSET, 5), PACKET(VC4_PACKET_CLIP_WINDOW, 9), - PACKET(VC4_PACKET_VIEWPORT_OFFSET, 5), + PACKET_DUMP(VC4_PACKET_VIEWPORT_OFFSET, 5), PACKET(VC4_PACKET_Z_CLIPPING, 9), - PACKET(VC4_PACKET_CLIPPER_XY_SCALING, 9), - PACKET(VC4_PACKET_CLIPPER_Z_SCALING, 9), + PACKET_DUMP(VC4_PACKET_CLIPPER_XY_SCALING, 9), + PACKET_DUMP(VC4_PACKET_CLIPPER_Z_SCALING, 9), PACKET(VC4_PACKET_TILE_BINNING_MODE_CONFIG, 16), PACKET(VC4_PACKET_TILE_RENDERING_MODE_CONFIG, 11), PACKET(VC4_PACKET_CLEAR_COLORS, 14), - PACKET(VC4_PACKET_TILE_COORDINATES, 3), + PACKET_DUMP(VC4_PACKET_TILE_COORDINATES, 3), - PACKET(VC4_PACKET_GEM_HANDLES, 9), + PACKET_DUMP(VC4_PACKET_GEM_HANDLES, 9), }; void @@ -104,16 +194,21 @@ vc4_dump_cl(void *cl, uint32_t size, bool is_render) header != VC4_PACKET_GEM_HANDLES ?
