Also, valuable feedback from Ted has been incorporated, to avoid any possible side effects on regular use of the PCIe hotplug stuff (when used without pciehp_force=1 mod parm). * * * Fix PCIe Hotplug so that it works with ExpressCard slots on Dell notebooks in conjunction with the modparam of pciehp_force=1. The PCIe Hotplug driver has two shortcomings 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 probably others as well, which may lack ACPI BIOS support for this. There are four patches in this series: 01_pciehp_cosmetic_fixes.patch -- cosmetic fixes, mostly to keep checkpatch.pl happy 02_pciehp_handle_preinserted_card.patch -- fixes problem number 1 (above). 03_pciehp_split_pcie_init.patch -- preparation for the resume patch. 04_pciehp_resume.patch -- fixes problem number 2 (above). diffstat summary for 01_pciehp_cosmetic_fixes.patch only: drivers/pci/hotplug/pciehp_core.c | 6 - drivers/pci/hotplug/pciehp_ctrl.c | 2 drivers/pci/hotplug/pciehp_hpc.c | 119 ++++++++++++++-------------- 3 files changed, 65 insertions(+), 62 deletions(-) diffstat summary for the other three patches combined: drivers/pci/hotplug/pciehp.h | 3 drivers/pci/hotplug/pciehp_core.c | 21 ++- drivers/pci/hotplug/pciehp_ctrl.c | 2 drivers/pci/hotplug/pciehp_hpc.c | 194 ++++++++++++++++------------ 4 files changed, 134 insertions(+), 86 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/
