Subject: [PATCH v4] nvme: allow cmb and pmr emulation on same device
Date: Wed, 1 Jul 2020 14:48:56 -0700 [thread overview]
Message-ID: <20200701214858.28515-1-andrzej.jakowski@linux.intel.com> (raw)
Hi All,
Resending series recently posted on mailing list related to nvme device
extension with couple of fixes after review.
This patch series does following:
- Fixes problem where CMBS bit was not set in controller capabilities
register, so support for CMB was not correctly advertised to guest.
This is resend of patch that has been submitted and reviewed by
Klaus [1]
- Introduces BAR4 sharing between MSI-X vectors and CMB. This allows
to have CMB and PMR emulated on the same device. This extension
was indicated by Keith [2]
v4:
- modified BAR4 initialization, so now it consists of CMB, MSIX and
PBA memory regions overlapping on top of it. This reduces patch
complexity significantly (Klaus [5])
v3:
- code style fixes including: removal of spurious line break, moving
define into define section and code alignment (Klaus [4])
- removed unintended code reintroduction (Klaus [4])
v2:
- rebase on Kevin's latest block branch (Klaus [3])
- improved comments section (Klaus [3])
- simplified calculation of BAR4 size (Klaus [3])
v1:
- initial push of the patch
