[RFC PATCH 00/20] Use msi_chip to configure MSI/MSI-X in all platforms

From: Yijing Wang
Date: Tue Aug 12 2014 - 03:03:08 EST


This series is mainly to use msi_chip instead of currently weak arch functions
across all platforms. Also clean up current MSI code and make drivers support
MSI easier.

Yijing Wang (20):
x86/xen/MSI: Eliminate arch_msix_mask_irq() and arch_msi_mask_irq()
MSI: Clean up struct msi_chip argument
PCI/MSI: Remove useless bus->msi assignment
MSI: Remove the redundant irq_set_chip_data()
MSI: Refactor struct msi_chip to become more common
PCI/MSI: Introduce arch_get_match_msi_chip() to find the match
msi_chip
x86/MSI: Use msi_chip instead of arch func to configure MSI/MSI-X
x86/xen/MSI: Use msi_chip instead of arch func to configure MSI/MSI-X
irq_remapping/MSI: Use msi_chip instead of arch func to configure
