Assuming that cpu_has_bpext == T, suppose that bp_addr = 0x1001; bp_bp_addr_mask = 0xf; Is it the same as 0x1000/0xf above? IOW, what exactly this mask means? I guess, mem:ADDR:w:MASK should trigger the trap if CPU writes to the addr and (addr & ~MASK) == (ADDR & ~MASK) correct? And does attr.bp_len "contribute" to the mask? I mean, if bp_len == X86_BREAKPOINT_LEN_8, does this mean that bp_bp_addr_mask and (bp_bp_addr_mask | 7) have the same effect?
