[Xen-ia64-devel] [RFC] Patches for supporting Xwindow on our PRIMEQUEST

[Jun Kamada <kama@xxxxxxxxxxxxxx>]

Hi all.

Attached patch set is for supporting Xwindow on our PRIMEQUEST. Please refer
following URL about corresponding discussion.

http://lists.xensource.com/archives/html/xen-ia64-devel/2007-02/msg00212.html

Yamahata-san gave us a recommendation to perform ioremap in add_window()
function in "linux-2.6.18-xen/arch/ia64/pci/pci.c". However, resource
structure is not completely created on that place. 

Therefore, I added the ioremap() hypercall to where the resource structure
is already created. (bottom of pci_acpi_scan_root())

Following are brief description of the patches.

[1/4] revert_paravirt_pcimmap.patch: Revert paravirtualization to ioremap
                                     /proc/pci.
[2/4] remove_paravirt_dev_mem.patch: Disable paravirtualization to ioremap
                                     /dev/mem.
[3/4] ifdef_arch_has_dev_mem.patch: Add "#ifdef ARCH_HAS_DEV_MEM" to 
                                    archtecture specific file_operations.
[4/4] new_paravirt_pci.patch: Issue ioremap hypercall in pci_acpi_scan_root()
                              in order to map /dev/mem.

I will also post patch[3/4] to xen-devel mailing list after finishing
discussion on this mailing list.

I appreciate you to give us comments.

Best regards,
