Line 167:

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.

If a process has forcefully acquired rights (ErrDisp), attempting [[GSPGPU:SetLcdForceBlack|unset LCDs black-fill]] 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~~.

| Support for the new LINEAR memory region was implemented for cache commands and vaddr->paddr conversion. Support for the New3DS only [[Memory_layout#0x1F000000_.28New_3DS_only.29|QTM memory region]] was added for vaddr->paddr conversion. When vaddr->physaddr conversions fail while handling PSC commands, an error is now returned (see [[GSP_Shared_Memory#Command_Queue_Header|here]] regarding errors being written to GSP shared memory).
