Subject: [PATCH 33/46] [gdb/testsuite] Fix
|
|
gdb.arch/arm-single-step-kernel-helper.exp
|
|
|
|
On arm-linux I run into:
|
|
...
|
|
(gdb) p *kernel_user_helper_version^M
|
|
Cannot access memory at address 0xffff0ffc^M
|
|
(gdb) FAIL: gdb.arch/arm-single-step-kernel-helper.exp: check kernel helper version
|
|
...
|
|
|
|
What the test-case is trying to do, is to access a special address in the arm
|
|
linux kernel [1] using ptrace, which doesn't seem to work.
|
|
|
|
This is with kernel version 6.1.55. Perhaps this used to work, but the kernel
|
|
was modified to be more strict with respect to access to this special address.
|
|
|
|
Fix this by making the inferior access that special address instead.
|
|
|
|
Tested on arm-linux.
