So I got a fixed up gdb and I was testing the reading of the virtual
counter:
=> 0xffffff800854a118 <arch_counter_get_cntvct+16>: mrs x0, cntvct_el0
0xffffff800854a11c <arch_counter_get_cntvct+20>: b 0xffffff800854a148 <arch_counter_get_cntvct+64>
0xffffff800854a120 <arch_counter_get_cntvct+24>: adrp x0, 0xffffff800896a000 <scsi_format_log+3568>
0xffffff800854a124 <arch_counter_get_cntvct+28>: add x0, x0, #0x5a0
0xffffff800854a128 <erratum_set_next_event_tval_virt+4294964112>: mrs x1, tpidr_el1
p/x $x0
$6 = 0xffffff800854a108
p/x $cntvct_el0
$7 = 0x0
stepi
0xffffff800854a11c 160 return arch_timer_reg_read_stable(cntvct_el0);
=> 0xffffff800854a11c <arch_counter_get_cntvct+20>: b 0xffffff800854a148 <arch_counter_get_cntvct+64>
0xffffff800854a120 <arch_counter_get_cntvct+24>: adrp x0, 0xffffff800896a000 <scsi_format_log+3568>
0xffffff800854a124 <arch_counter_get_cntvct+28>: add x0, x0, #0x5a0
p/x $x0
$8 = 0x7a5b32b
p/x $cntvct_el0
$9 = 0x0
So I'm wondering why there is a disparity here?
