Subject: [PATCH v3 0/8] PCI: add and use constant PCI_STATUS_ERROR_BITS and helper pci_status_get_and_clear_errors
Date: Tue, 25 Feb 2020 15:03:05 +0100 [thread overview]
Message-ID: <20ca7c1f-7530-2d89-40a6-d97a65aa25ef@gmail.com> (raw)
Few drivers have own definitions for this constant, so move it to the
PCI core. In addition there are several places where the following
code sequence is used:
1. Read PCI_STATUS
2. Mask out non-error bits
3. Action based on set error bits
4. Write back set error bits to clear them
As this is a repeated pattern, add a helper to the PCI core.
Most affected drivers are network drivers. But as it's about core
PCI functionality, I suppose the series should go through the PCI
tree.
v2:
- fix formal issue with cover letter
v3:
- fix dumb typo in patch 7
Heiner Kallweit (8):
