I am attempting to write a routine to initialize the cache for a MIPS 4kc core to get Linux 2.6.16.14 to compile. I am sure someone has probably already done this, but I am doing it for educational reasons. I am receiving the following error: arch/mips/kernel/head.S: Assembler messages: arch/mips/kernel/head.S:131: Error: Instruction cache requires absolute expression >From the following code section: li t0, 0x80000000 # start address (KSEG0) addu t1,t0,0x2000 # 8KB I-cache 1: addu t0,0x10 # 16B line size cache Index_Store_Tag_I,-4(t0) # clear tag nop cache Fill_I,-4(t0) # fill line nop bne t0,t1,1b cache Index_Store_Tag_I,-4(t0) I copied the code section from See MIPS Run, so I know the code must be correct. What am I doing wrong?
