[PATCH v1 0/6] baseband/acc: fixes on top of RC2

[Nicolas Chautru]

A few fixes still required for the baseband acc PMDs
for ACC100 and ACC200 on top of RC2. Most of them
introduced recently including one covery warning.
All changes pushed in same serie for ease of review/apply.

Hernan Vargas (3):
  baseband/acc: fix PMON register values
  baseband/acc: fix double MSI intr in TB mode
  baseband/acc: fix redundant function definition

Nicolas Chautru (3):
  baseband/acc: fix LTE half iteration flag
  baseband/acc: fix to possible overflow
  baseband/acc: fix to acc200 access corner case

[PATCH v1 1/6] baseband/acc: fix LTE half iteration flag

[Nicolas Chautru]

The logic for that flag was inverted.
Specific to ACC200.
When starting with even iteration it actually runs
for an additional half iteration.

Fixes: bec597b78a0 ("baseband/acc200: add LTE processing")

[PATCH v1 2/6] baseband/acc: fix to possible overflow

[Nicolas Chautru]

Potential overflow issue when casting to 64bits,
notably relevant when extending number of queues.

[PATCH v1 3/6] baseband/acc: fix to acc200 access corner case

[Nicolas Chautru]

To enforce safe access to the ACC200 device, the PMD requires
to explicitly check that the device is in configured and
enabled state prior to accessing queue resources.
This is done by checking the Qmgr ingress queue status.

Fixes: 40e3adbdd3 ("baseband/acc200: add queue configuration")

[PATCH v1 4/6] baseband/acc: fix PMON register values

[Nicolas Chautru]

From: Hernan Vargas <hernan.vargas@intel.com>

Enable properly the PMon for ACC100.
Previous commit was missing actual implementation
and using incorrect register values.
