From: Nicolai Hähnle Date: Sun, 6 Sep 2009 13:03:51 +0000 (+0200) Subject: r300g: Debug flags infrastructure X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4b01e6f614052e48971f2b2ff474fb66afc4f752;p=mesa.git r300g: Debug flags infrastructure So that debugging is no longer a full-spam-or-nothing approach, you are now supposed to set the RADEON_DEBUG environment flag just like for classic Mesa. The available debug flags are different, however. Just running an OpenGL application with RADEON_DEBUG set to an arbitrary string will print out helpful information. Everything must be compiled with -DDEBUG for any of this to work --- diff --git a/src/gallium/drivers/r300/Makefile b/src/gallium/drivers/r300/Makefile index d7a2c8c462c..93c2152edce 100644 --- a/src/gallium/drivers/r300/Makefile +++ b/src/gallium/drivers/r300/Makefile @@ -9,6 +9,7 @@ C_SOURCES = \ r300_chipset.c \ r300_clear.c \ r300_context.c \ + r300_debug.c \ r300_emit.c \ r300_flush.c \ r300_fs.c \ diff --git a/src/gallium/drivers/r300/r300_context.c b/src/gallium/drivers/r300/r300_context.c index da67bc29b89..ef79d7bbbb6 100644 --- a/src/gallium/drivers/r300/r300_context.c +++ b/src/gallium/drivers/r300/r300_context.c @@ -146,6 +146,8 @@ struct pipe_context* r300_create_context(struct pipe_screen* screen, r300->context.winsys = (struct pipe_winsys*)r300_winsys; r300->context.screen = r300_screen(screen); + r300_init_debug(r300); + r300->context.destroy = r300_destroy_context; r300->context.clear = r300_clear; diff --git a/src/gallium/drivers/r300/r300_context.h b/src/gallium/drivers/r300/r300_context.h index f78492d4aa9..cd7b36b4678 100644 --- a/src/gallium/drivers/r300/r300_context.h +++ b/src/gallium/drivers/r300/r300_context.h @@ -275,6 +275,9 @@ struct r300_context { uint32_t dirty_state; /* Flag indicating whether or not the HW is dirty. */ uint32_t dirty_hw; + + /** Combination of DBG_xxx flags */ + unsigned debug; }; /* Convenience cast wrapper. */ @@ -288,4 +291,40 @@ struct draw_stage* r300_draw_stage(struct r300_context* r300); void r300_init_state_functions(struct r300_context* r300); void r300_init_surface_functions(struct r300_context* r300); +/* Debug functionality. */ + +/** + * Debug flags to disable/enable certain groups of debugging outputs. + * + * \note These may be rather coarse, and the grouping may be impractical. + * If you find, while debugging the driver, that a different grouping + * of these flags would be beneficial, just feel free to change them + * but make sure to update the documentation in r300_debug.c to reflect + * those changes. + */ +/*@{*/ +#define DBG_HELP 0x0000001 +#define DBG_FP 0x0000002 +#define DBG_VP 0x0000004 +#define DBG_CS 0x0000008 +#define DBG_DRAW 0x0000010 +/*@}*/ + +static INLINE boolean DBG_ON(struct r300_context * ctx, unsigned flags) +{ + return (ctx->debug & flags) ?
