paths in the kernel. Tests are intended to be run after building, installing
and booting a kernel.
Kselftest from mainline can be run on older stable kernels. Running tests
from mainline offers the best coverage. Several test rings run mainline
kselftest suite on stable releases. The reason is that when a new test
gets added to test existing code to regression test a bug, we should be
able to run that test on an older kernel. Hence, it is important to keep
code that can still test an older kernel and make sure it skips the test
gracefully on newer releases.
You can find additional information on Kselftest framework, how to
write new tests using the framework on Kselftest wiki:

Garbage collect fbdev scrolling acceleration
--------------------------------------------
Scroll acceleration has been disabled in fbcon. Now it works as the old
SCROLL_REDRAW mode. A ton of code was removed in fbcon.c and the hook bmove was
removed from fbcon_ops.
Remaining tasks:
- a bunch of the hooks in fbcon_ops could be removed or simplified by calling
directly instead of the function table (with a switch on p->rotate)
- fb_copyarea is unused after this, and can be deleted from all drivers
- after that, fb_copyarea can be deleted from fb_ops in include/linux/fb.h as
well as cfb_copyarea
Note that not all acceleration code can be deleted, since clearing and cursor
support is still accelerated, which might be good candidates for further
deletion projects.

This option adds the workaround for ARM Cortex-A510 erratum 2077057.
Affected Cortex-A510 may corrupt SPSR_EL2 when the a step exception is
expected, but a Pointer Authentication trap is taken instead. The
erratum causes SPSR_EL1 to be copied to SPSR_EL2, which could allow
EL1 to cause a return to EL2 with a guest controlled ELR_EL2.
This can only happen when EL2 is stepping EL1.
When these conditions occur, the SPSR_EL2 value is unchanged from the
previous guest entry, and can be restored from the in-memory copy.
If unsure, say Y.

This option adds the workaround for ARM Cortex-A510 erratum 2064142.
Affected Cortex-A510 core might fail to write into system registers after the
TRBE has been disabled. Under some conditions after the TRBE has been disabled
writes into TRBE registers TRBLIMITR_EL1, TRBPTR_EL1, TRBBASER_EL1, TRBSR_EL1,

bool "Cortex-A510: 2038923: workaround TRBE corruption with enable"
depends on COMPILE_TEST # Until the CoreSight TRBE driver changes are in
default y
help
This option adds the workaround for ARM Cortex-A510 erratum 2038923.
Affected Cortex-A510 core might cause an inconsistent view on whether trace is
prohibited within the CPU. As a result, the trace buffer or trace buffer state
might be corrupted. This happens after TRBE buffer has been enabled by setting
TRBLIMITR_EL1.E, followed by just a single context synchronization event before
execution changes from a context, in which trace is prohibited to one where it
isn't, or vice versa. In these mentioned conditions, the view of whether trace
is prohibited is inconsistent between parts of the CPU, and the trace buffer or
the trace buffer state might be corrupted.
Work around this in the driver by preventing an inconsistent view of whether the
trace is prohibited or not based on TRBLIMITR_EL1.E by immediately following a
change to TRBLIMITR_EL1.E with at least one ISB instruction before an ERET, or
two ISB instructions if no ERET is to take place.
If unsure, say Y.

help
This option adds the workaround for ARM Cortex-A510 erratum 1902691.
Affected Cortex-A510 core might cause trace data corruption, when being written
into the memory. Effectively TRBE is broken and hence cannot be used to capture
trace data.
Work around this problem in the driver by just preventing TRBE initialization on
affected cpus. The firmware must have disabled the access to TRBE for the kernel
on such implementations. This will cover the kernel for any firmware that doesn't
do this already.
If unsure, say Y.
