Hi Ming The latest patchset is [PATCH v11 00/15] PCI: ARM64 ECAM quirks You can get them from https://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git (pci/ecam) Thanks Dongdong 在 2016/12/22 16:31, Ming Lei 写道:

The two patches respectively: - provides the common function acpi_get_rc_resources() for ARM64 platform. - adds the HiSilicon ACPI specific quirks. This patchset is based on branch pci/ecam-v6 It can be found here: https://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git(pci/ecam-v6) This patchset has been tested on HiSilicon D03 board. The dmesg log, /proc/iomem, and ACPI table information can be found: https://bugzilla.kernel.org/show_bug.cgi?id=187961 v5 -> v6: - change the config option to CONFIG_PCI_ECAM_QUIRKS. - fix some commets about acpi_get_rc_resources().Could you post out v7 for fixing conflicts against current linus tree? BTW, I tried to fix the conflicts by myself, but still caues the following build failure: [tom@linux-2.6-vm]$make -j4 CROSS_COMPILE=aarch64-linux-gnu- ARCH=arm64 drivers/pci/host/pcie-hisi-acpi.o CHK include/config/kernel.release CHK include/generated/uapi/linux/version.h CHK include/generated/utsrelease.h CHK include/generated/timeconst.h CHK include/generated/bounds.h CHK include/generated/asm-offsets.h CALL scripts/checksyscalls.sh CC drivers/pci/host/pcie-hisi-acpi.o In file included from drivers/pci/host/pcie-hisi-acpi.c:16:0: drivers/pci/host/../pci.h:357:18: error: conflicting types for ‘acpi_get_rc_resources’ struct resource *acpi_get_rc_resources(const char *hid, u16 segment); ^ drivers/pci/host/../pci.h:352:5: note: previous declaration of ‘acpi_get_rc_resources’ was here int acpi_get_rc_resources(struct device *dev, const char *hid, u16 segment, ^ scripts/Makefile.build:293: recipe for target 'drivers/pci/host/pcie-hisi-acpi.o' failed make[1]: *** [drivers/pci/host/pcie-hisi-acpi.o] Error 1 Makefile:1640: recipe for target 'drivers/pci/host/pcie-hisi-acpi.o' failed make: *** [drivers/pci/host/pcie-hisi-acpi.o] Error 2 Thanks, Mingv4 -> v5: - obtain rc base addresses from PNP0C02 at the root of the ACPI namespace (under \_SB) instead of from sub-device under the RC. - merge the rewrited get rc resources code by Tomasz. - delete unused code. - drop the PATCH V4 1/2, will rework late as a separate patch. v3 -> v4: - rebase on pci/ecam-v6. - delete the unnecessary link_up check code. v2 -> v3: - rebase against 4.9-rc1 and add Tomasz quirks V6 pathcset. - obtain rc base addresses from PNP0C02 as subdevice of PNP0A03 instead of hardcode the addresses. - modify hisi_pcie_acpi_rd_conf/hisi_pcie_acpi_wr_conf() according to Arnd comments. v1 -> v2: - rebase against Tomasz RFC V5 quirk mechanism - add ACPI support for the HiSilicon Hip07 SoC PCIe controllers.
