X-Git-Tag: v3.2-rc1~192^4~6 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=917e3e65c35459d52f0d0b890aa5df0cad07a051;p=pandora-kernel.git xen-pcifront: Update warning comment to use 'e820_host' option. With Xen changeset 23428 "libxl: Add 'e820_host' option to config file" the E820 as seen from the host can now be passed into the guest. This means that a PV guest can now: - Use the correct PCI I/O gap. Before these patches, Linux guest would boot up and would tell: [ 0.000000] Allocating PCI resources starting at 40000000 (gap: 40000000:c0000000) while in actuality the PCI I/O gap should have been: [ 0.000000] Allocating PCI resources starting at b0000000 (gap: b0000000:4c000000) - The PV domain with PCI devices was limited to 3GB. It now can be booted with 4GB, 8GB, or whatever number you want. The PCI devices will now _not_ conflict with System RAM. Meaning the drivers can load.
