FPU usage in kernel space was allowed / enabled with ipipe, but is no
longer available for dovetail based kernels. That allows us to clean
up the FPU related tests of the switchtest utility.
fp_kernel_supported() can be removed as all supported architectures
returned 0 already. That allows us to
On x86 fp_regs_set() expects that the FPU state was initialized by
calling the fninit instruction. When running the tests in kernel space
in task context there is no guarantee that the FPU was initialized so
under heavy load / scheduling the test might fail and report a FPU
register corruption.
Parts of the FPU tests were skipped when one of the following config
options was enabled, shadowing a real test issue that was triggered by
high load on the system. The options:
- CONFIG_X86_USE_3DNOW
- CONFIG_MD_RAID456
- CONFIG_MD_RAID456_MODULE
As the FPU initialization is fixed now, we
Hi all,
this is the backport of the previously pulished FPU testing cleanup. As
3.2 stable branch still supports ipipe and ipipe allows us to use the
FPU in kernel space (in user task context) we have to deal with the
problem differently.
The x86 fpu test relied on getting a clean fpu state
