The PCIe Hotplug driver has two issues when used on Dell notebooks which lack ACPI BIOS support for PCIe hotplug: 1. The driver does not recognise cards that were inserted prior to the driver being modprobe'd. 2. The driver stops functioning after a suspend/resume (RAM) cycle, and needs to be rmmod'd and modprobe'd to get it working again. This patch series addresses those issues, resulting in a completely functional PCIe Hotplug driver for Dell notebooks, and possibly others as well which may lack ACPI BIOS support for this. Note that pciehp_force=1 is (still) required. There are three patches in this series: 01_pciehp_handle_preinserted_card.patch -- fixes problem number 1 (above). 02_pciehp_split_pcie_init.patch -- preparation for the resume patch. 03_pciehp_resume_reinit_hardware.patch -- fixes problem number 2 (above). diffstat summary for the three patches combined: drivers/pci/hotplug/pciehp.h | 3 drivers/pci/hotplug/pciehp_core.c | 23 +++ drivers/pci/hotplug/pciehp_ctrl.c | 2 drivers/pci/hotplug/pciehp_hpc.c | 185 +++++++++++++++------------- 4 files changed, 130 insertions(+), 83 deletions(-) Cheers -- Mark Lord - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
