semi true. L1 text appears to work fine: (gdb) stepi 0xffa02aac in moo () (gdb) dis Dump of assembler code from 0xffa02aac to 0xffa02aec: 0xffa02aac <moo+0>: LINK 0xc; /* (12) */ 0xffa02ab0 <moo+4>: [FP + 0x8] = R0; .... but L1 data doesnt seem to work (probably something simple to fix in our kernel ptrace?): (gdb) print i Cannot access memory at address 0xff803e58 the simple code: int i __attribute__((l1_data)); > So this part of code was not got exercised.
