[ralf@linux-mips.org: Drop removal of exception codes. I don't care what the incomplete architecture spec says; it can't change existing hardware and VCEI is supported indeed.] Signed-off-by: James Hogan Cc: linux-mips@linux-mips.org Cc: Paolo Bonzini Cc: Gleb Natapov Cc: kvm@vger.kernel.org Patchwork: https://patchwork.linux-mips.org/patch/11890/ Signed-off-by: Ralf Baechle --- diff --git a/arch/mips/include/asm/mipsregs.h b/arch/mips/include/asm/mipsregs.h index eb89b877c6c9..3ad19ad04d8a 100644 --- a/arch/mips/include/asm/mipsregs.h +++ b/arch/mips/include/asm/mipsregs.h @@ -420,12 +420,20 @@ #define EXCCODE_CPU 11 /* Coprocessor unusable */ #define EXCCODE_OV 12 /* Arithmetic overflow */ #define EXCCODE_TR 13 /* Trap instruction */ -#define EXCCODE_VCEI 14 /* Virtual coherency exception */ #define EXCCODE_MSAFPE 14 /* MSA floating point exception */ #define EXCCODE_FPE 15 /* Floating point exception */ +#define EXCCODE_TLBRI 19 /* TLB Read-Inhibit exception */ +#define EXCCODE_TLBXI 20 /* TLB Execution-Inhibit exception */ #define EXCCODE_MSADIS 21 /* MSA disabled exception */ +#define EXCCODE_MDMX 22 /* MDMX unusable exception */ #define EXCCODE_WATCH 23 /* Watch address reference */ -#define EXCCODE_VCED 31 /* Virtual coherency data */ +#define EXCCODE_MCHECK 24 /* Machine check */ +#define EXCCODE_THREAD 25 /* Thread exceptions (MT) */ +#define EXCCODE_DSPDIS 26 /* DSP disabled exception */ +#define EXCCODE_GE 27 /* Virtualized guest exception (VZ) */ + +/* Implementation specific trap codes used by MIPS cores */ +#define MIPS_EXCCODE_TLBPAR 16 /* TLB parity error exception */ /* * Bits in the coprocessor 0 config register.
