debug dmesg output including drawpix run
The kernel drm savage_drv.h lists this information:
#define SAVAGE_FB_SIZE_S3 0x01000000 /* 16MB */
#define SAVAGE_FB_SIZE_S4 0x02000000 /* 32MB */
#define SAVAGE_MMIO_SIZE 0x00080000 /* 512kB */
#define SAVAGE_APERTURE_OFFSET 0x02000000 /* 32MB */
#define SAVAGE_APERTURE_SIZE 0x05000000 /* 5 tiled surfaces, 16MB each
*/
I also noticed in drm debug information that drmMapBufs() at savage_xmesa.c:252
returns 0. Is this an issue?
