Subject: [PATCH v1 00/21] Use MSI chip to configure MSI/MSI-X in all platforms
Date: Fri, 5 Sep 2014 18:09:45 +0800 [thread overview]
Message-ID: <1409911806-10519-1-git-send-email-wangyijing@huawei.com> (raw)
This series is based Bjorn's pci-next branch + Alexander Gordeev's two patches
"Remove arch_msi_check_device()" link: https://lkml.org/lkml/2014/7/12/41
Currently, there are a lot of weak arch functions in MSI code.
Thierry Reding Introduced MSI chip framework to configure MSI/MSI-X in arm.
This series use MSI chip framework to refactor MSI code across all platforms
to eliminate weak arch functions. It has been tested fine in x86(with or without
irq remap).
RFC->v1: Updated "[patch 4/21] x86/xen/MSI: Eliminate...", export msi_chip instead
of #ifdef to fix MSI bug in xen running in x86.
Rename arch_get_match_msi_chip() to arch_find_msi_chip().
Drop use struct device as the msi_chip argument, we will do that
later in another patchset.
Yijing Wang (21):
PCI/MSI: Clean up struct msi_chip argument
PCI/MSI: Remove useless bus->msi assignment
MSI: Remove the redundant irq_set_chip_data()
x86/xen/MSI: Eliminate arch_msix_mask_irq() and arch_msi_mask_irq()
PCI/MSI: Introduce weak arch_find_msi_chip() to find MSI chip
PCI/MSI: Refactor struct msi_chip to make it become more common
x86/MSI: Use MSI chip framework to configure MSI/MSI-X irq
x86/xen/MSI: Use MSI chip framework to configure MSI/MSI-X irq
