Subject: [PATCH 0/2] cxl/region: Improve Soft Reserved resource handling
Date: Fri, 23 Jun 2023 18:24:55 -0700	[thread overview]
Message-ID: <cover.1687568084.git.alison.schofield@intel.com> (raw)

From: Alison Schofield <alison.schofield@intel.com>

Make the cxl/region drivers handle these 2 observed scenarios:

1) Soft reserved resources were observed as sometimes being the parent
and sometimes being the child of a region resource. Patch 1 clears up
that inconsistency.

2) Soft reserved resources were also observed as stranded after region 
teardown, making the address space the region released unavailable for
reallocation. Patch 2 implements soft reserved resource removal.


Alison Schofield (2):
  cxl/region: Try to add a region resource to a soft reserved parent
  cxl/region: Remove a soft reserved resource at region teardown
