Hi,
Back in 2.6.16.29, there were a lot changes made to
support MT_SMTC. Among them were changes to the
include/asm-mips/interrupt.h:
__asm__ (
" .macro local_irq_enable \n"
" .set push \n"
" .set reorder \n"
" .set noat \n"
#ifdef CONFIG_CPU_MIPSR2
" .set mips32r2 \n"
#ifdef CONFIG_MIPS_MT_SMTC
"mfc0 $1, $2, 1 # SMTC - clear TCStatus.IXMT \n"
"ori $1, 0x400 \n"
"xori $1, 0x400 \n"
"mtc0 $1, $2, 1 \n"
#else
" .set mips32r2 \n"
" ei \n"
" .set mips0 \n"
#endif
#else
" mfc0 $1,$12 \n"
" ori $1,0x1f \n"
" xori $1,0x1e \n"
" mtc0 $1,$12 \n"
#endif
" irq_enable_hazard \n"
" .set pop \n"
" .endm");
Am I missing something, or is the second ".set
mips32r2 \n" (line 51) redundant?
Thanks,
Larry Stefani
