The GSP module starts a thread for handling commands for each service session, a maximum of 4 processes can use this service at once. Official applications have an optional code-path which [[GSPGPU:WriteHWRegs|writes]] to registers during initialization, this is normally not used however.
The GSP module starts a thread for handling commands for each service session, a maximum of 4 processes can use this service at once. Official applications have an optional code-path which [[GSPGPU:WriteHWRegs|writes]] to registers during initialization, this is normally not used however.
If a process has acquired rights, attempting to [[GSPGPU:SetLcdForceBlack|set LCDs to black]] from another process will fail.
Saving/restoring VRAM requires bit0 of process [[GSPGPU:RegisterInterruptRelayQueue|flags]] to be set.

| Support for the new LINEAR memory region was implemented(for cache commands and vaddr->physaddr conversion). Support for the new process-mem 0x1E800000 region(however the GPU can't actually access this memory) was added for vaddr->physaddr conversion. Originally GSP module ignored vaddr->physaddr conversion errors(like with vaddrs outside of the handled ranges) and just wrote physaddr value0 to the GPU registers, however now GSP module returns an error for that instead(see [[GSP_Shared_Memory#Command_Buffer_Header|here]] regarding errors being written to GSP shared-mem). New services commands were added too, see above.

There's separate GSP-module titles for Old3DS and New3DS. PTM CheckNew3DS is only used by the New3DS title, for copying that flag into a state field. Elsewhere that field is checked for running additional code only on New3DS, for processing various state / using [[QTM_Services|QTM]] commands.
