From 7b6a7d7dfb92d7a6d3537ea8b0339c2170d7eb84 Mon Sep 17 00:00:00 2001 From: Tony Wasserka Date: Sun, 3 Aug 2014 01:46:47 +0200 Subject: Pica/GPU: Change hardware registers to use physical addresses rather than virtual ones. This cleans up the mess that address reading/writing had become and makes the code a *lot* more sensible. This adds a physical<->virtual address converter to mem_map.h. For further accuracy, we will want to properly extend this to support a wider range of address regions. For now, this makes simply homebrew applications work in a good manner though. --- src/core/hw/gpu.h | 66 ------------------------------------------------------- 1 file changed, 66 deletions(-) (limited to 'src/core/hw/gpu.h') diff --git a/src/core/hw/gpu.h b/src/core/hw/gpu.h index 3065da89..d20311a0 100644 --- a/src/core/hw/gpu.h +++ b/src/core/hw/gpu.h @@ -249,72 +249,6 @@ static_assert(sizeof(Regs) == 0x1000 * sizeof(u32), "Invalid total size of regis extern Regs g_regs; -enum { - TOP_ASPECT_X = 0x5, - TOP_ASPECT_Y = 0x3, - - TOP_HEIGHT = 240, - TOP_WIDTH = 400, - BOTTOM_WIDTH = 320, - - // Physical addresses in FCRAM (chosen arbitrarily) - PADDR_TOP_LEFT_FRAME1 = 0x201D4C00, - PADDR_TOP_LEFT_FRAME2 = 0x202D4C00, - PADDR_TOP_RIGHT_FRAME1 = 0x203D4C00, - PADDR_TOP_RIGHT_FRAME2 = 0x204D4C00, - PADDR_SUB_FRAME1 = 0x205D4C00, - PADDR_SUB_FRAME2 = 0x206D4C00, - // Physical addresses in FCRAM used by ARM9 applications -/* PADDR_TOP_LEFT_FRAME1 = 0x20184E60, - PADDR_TOP_LEFT_FRAME2 = 0x201CB370, - PADDR_TOP_RIGHT_FRAME1 = 0x20282160, - PADDR_TOP_RIGHT_FRAME2 = 0x202C8670, - PADDR_SUB_FRAME1 = 0x202118E0, - PADDR_SUB_FRAME2 = 0x20249CF0,*/ - - // Physical addresses in VRAM - // TODO: These should just be deduced from the ones above - PADDR_VRAM_TOP_LEFT_FRAME1 = 0x181D4C00, - PADDR_VRAM_TOP_LEFT_FRAME2 = 0x182D4C00, - PADDR_VRAM_TOP_RIGHT_FRAME1 = 0x183D4C00, - PADDR_VRAM_TOP_RIGHT_FRAME2 = 0x184D4C00, - PADDR_VRAM_SUB_FRAME1 = 0x185D4C00, - PADDR_VRAM_SUB_FRAME2 = 0x186D4C00, - // Physical addresses in VRAM used by ARM9 applications -/* PADDR_VRAM_TOP_LEFT_FRAME2 = 0x181CB370, - PADDR_VRAM_TOP_RIGHT_FRAME1 = 0x18282160, - PADDR_VRAM_TOP_RIGHT_FRAME2 = 0x182C8670, - PADDR_VRAM_SUB_FRAME1 = 0x182118E0, - PADDR_VRAM_SUB_FRAME2 = 0x18249CF0,*/ -}; - -/// Framebuffer location -enum FramebufferLocation { - FRAMEBUFFER_LOCATION_UNKNOWN, ///< Framebuffer location is unknown - FRAMEBUFFER_LOCATION_FCRAM, ///< Framebuffer is in the GSP heap - FRAMEBUFFER_LOCATION_VRAM, ///< Framebuffer is in VRAM -}; - -/** - * Sets whether the framebuffers are in the GSP heap (FCRAM) or VRAM - * @param - */ -void SetFramebufferLocation(const FramebufferLocation mode); - -/** - * Gets a read-only pointer to a framebuffer in memory - * @param address Physical address of framebuffer - * @return Returns const pointer to raw framebuffer - */ -const u8* GetFramebufferPointer(const u32 address); - -u32 GetFramebufferAddr(const u32 address); - -/** - * Gets the location of the framebuffers - */ -FramebufferLocation GetFramebufferLocation(u32 address); - template void Read(T &var, const u32 addr); -- cgit v1.2.3
