Excuse me, I want to consult the related information about SPR. For SPRs (Special Purpose Register) under tilegx, I can not get related documents (I only got the tilepro related document for SPR). After read through the source code of Linux kernel for tile, I guess:
- SPRs are in "arch/tile/include/uapi/arch/spr_def_64.h". - SPRs are all 64-bit registers (I referenced the 'interrupt_mask' and CHIP_HAS_SPLIT_INTR_MASK to know about it). If what I guess is incorrect, please let me know. And welcome to provide tilegx SPR related documents, too. Thanks.
