AS3.0 IPF: Inclusion of zx1 hot-plug support
Last modified: 2016-04-18 05:39:59 EDT
PROBLEM: zx1 hot-plug support not available. FIX EXISTS in Greg Cage Package; HP would develop: HP is working on zx1 PCI hot-plug support. Evaluating device-specific vs. ACPI implementations. Would be nice to only do for 2.5, but would consider 2.4 depending on RHAS kernel plans BUSINESS CASE: Telco market feature. Requirement for high-end boxes (where we support hot-plug everything). Support of Diablo, Orca, Eiger, and Olympia. DATE REQUIRED: With 3.0 ---------- Action by: charline.polifka Issue Registered ---------- Action by: ltroan HP to develop code (on Greg Cage package) charline.polifka assigned to issue for HP-IPF. Category set to: Applications Status set to: Waiting on Client (Long Term) ---------- Action by: charline.polifka Attached are the patches: These four patches against 2.4.20 are required to support pci hotplug on Diablo. PLEASE NOTE: Further patches are required for ACPI to support hotplug on Pinnacles-based systems. These patches are being written by Intel and are not yet available. Further patches are required to support HP ACPI extensions to report latch status and set attention button status. These patches are not yet available as no firmware has been released which implements this functionality. Patch 01 is the changes between 2.4.20 and 2.4.21-pre1 in the acpiphp hotplug driver. Patch 02 is required to find the zx1 hotplug controllers. It requires a version of ACPI later than that shipped in stock 2.4.20. That shipped in the 2.4.20-ia64 patch is sufficiently recent. This patch has been approved by GregKH but is not accepted into 2.4.21 due to its requirements for a more recent ACPI. Patch 03 is required for card insertion. It implements the Linux 2.5 internal interface for accessing PCI config space and reimplements the Linux 2.4 interface on top of it. This patch has been approved by GregKH and accepted into 2.4.21-pre3. Patch 04 is also required for card insertion. It converts the acpiphp driver to use the new PCI config space accessor interfaces. This patch has also been approved by GregKH and accepted into 2.4.21-pre3.

Mail sent to Alan Meyer on 4/16 to prompt him to get required ACPI GPE patch from Robert Moore of Intel. No progress can be made without this.
Larry gave Bjorn a new kernel last week and Bjorn is verifying that the support is included.
This is an old bug report that was a dup of another bug report (although I can't remember the other bug reports number right now). Closing this one out.
