Subject: [PATCH v2 0/3] Allow EINJ to inject memory error to NVDIMM
Date: Fri, 23 Oct 2015 12:53:56 -0600 [thread overview]
Message-ID: <1445626439-8424-1-git-send-email-toshi.kani@hpe.com> (raw)
This patch-set extends the EINJ driver to allow injecting a memory
error to NVDIMM. It first extends iomem resource interface to support
checking a NVDIMM region.
Patch 1/3 changes region_intersects() to accept non-RAM regions, and
adds region_intersects_ram().
Patch 2/3 adds region_intersects_pmem() to check a NVDIMM region.
Patch 3/3 changes the EINJ driver to allow injecting a memory error
to NVDIMM.
---
v2:
- Change the EINJ driver to call region_intersects_ram() for checking
RAM with a specified size. (Dan Williams)
- Add export to region_intersects_ram().

Toshi Kani (3):
1/3 resource: Add @flags to region_intersects()
2/3 resource: Add region_intersects_pmem()
3/3 ACPI/APEI/EINJ: Allow memory error injection to NVDIMM
