Once we start getting many devices sharing the irq in an irq list, this may help the list traversal latency. V1: Couple of RFC patches here. I don't really notice a positive benefit but it does reduce the struct size of vmd_irq_list and hopefully we gain some cache benefits from that. Both are based on: https://patchwork.kernel.org/patch/9304179/ https://patchwork.kernel.org/patch/9304181/ Jon Derrick (3): vmd: eliminate vmd_vector member from list type vmd: eliminate index member from irq list pci/vmd: Create irq map for irq nodes arch/x86/pci/vmd.c | 94 ++++++++++++++++++++++++++++++++++++++++++------------ 1 file changed, 73 insertions(+), 21 deletions(-) -- 1.8.3.1
