I tweaked the PME/hotplug no-MSI logic in pcie_init_service_irqs() because I thought it was getting hard to read with the negations and conjunctions. Please double-check to make sure I didn't break it. https://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git/log/?h=pci/portdrv I also capitalized your name consistently, Gabriele :)

From: gabriele paoloni <gabriele.paoloni@huawei.com> This patchset: 1) adds support for MSI interrupt vectors to be used for Roor Port services 2) adds support for DPC Root Port service interrupt The patchset has been tested on Hisilicon Hip08 Chipset Changes from v4: - removed meaningless comment Changes from v3: - removed 2 extra lines at the bottom of comments Changes from v2: - Fixed comment mismatch for function pcie_port_enable_irq_vec - removed redundant commet on pci_irq_vector() Changes from v1: According to comments from Christoph Hellwig in https://www.spinics.net/lists/kernel/msg2508842.html and https://www.spinics.net/lists/kernel/msg2508850.html - reduced the calls of pci_alloc_irq_vectors by ORing PCI_IRQ_MSIX and PCI_IRQ_MSI - used a unique macro for the max number of MSI/MSIx interrupt vectors - reworked pcie_init_service_irqs() to call pci_alloc_irq_vectors() only for legacy IRQ Gabriele Paoloni (1): PCI/portdrv: add support for different MSI interrupts for PCIe port services gabriele paoloni (1): PCI/portdrv: allocate MSI/MSIx vector for DPC RP service drivers/pci/pcie/portdrv.h | 8 ++++-- drivers/pci/pcie/portdrv_core.c | 63 +++++++++++++++++++++++++++++------------ 2 files changed, 50 insertions(+), 21 deletions(-) -- 2.7.4
