ecc_inject: Add Hygon Dhyana support.
Eliminate the arena parameter to kmem_free(). Implicitly this corrects an2018-08-25T19:38:08ZAlan Coxalc@FreeBSD.org2018-08-25T19:38:08Zurn:sha1:49bfa624ac861d7fafc87f06dc2cdf4972aed854
error in the function hypercall_memfree(), where the wrong arena was being
passed to kmem_free().
Introduce a per-page flag, VPO_KMEM_EXEC, to mark physical pages that are
mapped in kmem with execute permissions. Use this flag to determine which
arena the kmem virtual addresses are returned to.
Eliminate UMA_SLAB_KRWX. The introduction of VPO_KMEM_EXEC makes it
redundant.
Update the nearby comment for UMA_SLAB_KERNEL.

add a module that provides support for DRAM ECC error injection on AMD CPUs2017-03-03T22:51:04ZAndriy Gaponavg@FreeBSD.org2017-03-03T22:51:04Zurn:sha1:f5aac9074a9467cb8c3b55365f9e7ad8b6ac2a3c
I imagine that the module would be useful only to a very limited number
of developers, so that's my excuse for not writing any documentation.
On a more serious note, please see DRAM Error Injection section of BKDGs
for families 10h - 16h. E.g. section 2.13.3.1 of BKDG for AMD Family 15h
Models 00h-0Fh Processors.
Many thanks to kib for his suggestions and comments.
