From e4bd0bddeaaec31a13484bc791e181052211d9ad Mon Sep 17 00:00:00 2001 From: Subv Date: Mon, 23 Apr 2018 11:06:07 -0500 Subject: Nvdrv/nvhost-as-gpu: Implemented the ioctl REMAP command. It takes a previously-reserved (AllocateSpace) GPU memory address and maps it to the address of the nvmap object passed to Remap. --- src/core/hle/service/nvdrv/devices/nvhost_as_gpu.h | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'src/core/hle/service/nvdrv/devices/nvhost_as_gpu.h') diff --git a/src/core/hle/service/nvdrv/devices/nvhost_as_gpu.h b/src/core/hle/service/nvdrv/devices/nvhost_as_gpu.h index d86c3ebd9..f2dd0c3b3 100644 --- a/src/core/hle/service/nvdrv/devices/nvhost_as_gpu.h +++ b/src/core/hle/service/nvdrv/devices/nvhost_as_gpu.h @@ -26,6 +26,7 @@ private: enum class IoctlCommand : u32_le { IocInitalizeExCommand = 0x40284109, IocAllocateSpaceCommand = 0xC0184102, + IocRemapCommand = 0x00000014, IocMapBufferExCommand = 0xC0284106, IocBindChannelCommand = 0x40044101, IocGetVaRegionsCommand = 0xC0404108, @@ -54,6 +55,16 @@ private: }; static_assert(sizeof(IoctlAllocSpace) == 24, "IoctlInitalizeEx is incorrect size"); + struct IoctlRemapEntry { + u16_le flags; + u16_le kind; + u32_le nvmap_handle; + INSERT_PADDING_WORDS(1); + u32_le offset; + u32_le pages; + }; + static_assert(sizeof(IoctlRemapEntry) == 20, "IoctlRemapEntry is incorrect size"); + struct IoctlMapBufferEx { u32_le flags; // bit0: fixed_offset, bit2: cacheable u32_le kind; // -1 is default @@ -91,6 +102,7 @@ private: u32 InitalizeEx(const std::vector& input, std::vector& output); u32 AllocateSpace(const std::vector& input, std::vector& output); + u32 Remap(const std::vector& input, std::vector& output); u32 MapBufferEx(const std::vector& input, std::vector& output); u32 BindChannel(const std::vector& input, std::vector& output); u32 GetVARegions(const std::vector& input, std::vector& output); -- cgit v1.2.3
