* [libata] Link power management infrastructureKristen Carlson Accardi2007-10-291-0/+19
| | | | | | | | | | | | | | | | | | | | | | Device Initiated Power Management, which is defined in SATA 2.5 can be enabled for disks which support it. This patch enables DIPM when the user sets the link power management policy to "min_power". Additionally, libata drivers can define a function (enable_pm) that will perform hardware specific actions to enable whatever power management policy the user set up for Host Initiated Power management (HIPM). This power management policy will be activated after all disks have been enumerated and intialized. Drivers should also define disable_pm, which will turn off link power management, but not change link power management policy. Documentation/scsi/link_power_management_policy.txt has additional information. Signed-off-by: Kristen Carlson Accardi <kristen.c.accardi@intel.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a quirk from LinuxBIOS to force enable HPET on the nVidia CK804 (nForce 4) chipset. This quirk can very likely support more than just nForce 4 (LinuxBIOS use the same code for nForce 5), and possibly nForce 3, but I don't have those chipsets, so cannot add and test them. Tested on an Abit KN9 (CK804).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Version 2.07 of the boot protocol uses 0x23C for the hardware_subarch field, that for lguest is "1". This allows us to use the standard boot entry point rather than the "GenuineLguest" string hack. The standard entry point also clears the BSS and copies the boot parameters and commandline for us, saving more code. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently discard console and network input when the guest has no input buffers. This patch changes that, so that we simply stop listening to that fd until the guest refills its input buffers. This is particularly important because hvc_console without interrupts does backoff polling and so often lose characters if we discard. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1) This allows us to get alot closer to booting bzImages. 2) It means we don't have to know page_offset. 3) The Guest needs to modify the boot pagetables to create the PAGE_OFFSET mapping before jumping to C code. 4) guest_pa() walks the page tables rather than using page_offset. 5) We don't use page_offset to figure out whether to emulate: it was always kinda quesationable, and won't work for instructions done before remapping (bzImage unpacking in particular). 6) We still want the kernel address for tlb flushing: have the initial hypercall give us that, too.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce intel_iommu=forcedac commandline option. This option is helpful to verify the pci device capability of handling physical dma'able address greater than 4G.

Hardware spec can be found at: http://www.intel.com/technology/virtualization This driver sets X86_64 'dma_ops', so hook into standard DMA APIs. In this way, PCI driver will get virtual DMA address.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Updates for version 2.07 of the boot protocol. This includes: load_flags.KEEP_SEGMENTS- flag to request/inhibit segment reloads hardware_subarch - what subarchitecture we're booting under hardware_subarch_data - per-architecture data The intention of these changes is to make booting a paravirtualized kernel work via the normal Linux boot protocol.
