[Xen-devel] [GIT PULL] pv/pcifront-2.6.32
Hey Jeremy,
Please pull from
git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git pv/pcifront-2.6.32
It is a back-port of the Xen PCI front driver (not the SR-IOV one, just
old plain one). It has been tested with a bare 2.6.32 tree
(pv/master.2.6.32) and with xen/next
The merge of this is a bit hairy, so I did my own which is available in
the pv/xen.next.merge (which is basically xen/next + pv/pcifront-2.6.32
+ pv/fbfbront + xen: Allow unprivileged Xen domains to create iomap
pages).
To make the PCI front driver work, another patch has to be put added in
the xen/next (or better yet in the swiotlb - but it really does not seem
to fit there), which is the "xen: Allow unprivileged Xen domains to
create iomap pages" (5a7357bdb10b40414d97d7582f5467e4a709bd07)
Alex Nixon (3):
xen: Don't disable the I/O space
x86/PCI: Clean up pci_cache_line_size
x86/PCI: Enable scanning of all pci functions
Ian Campbell (1):
xen: fix off-by-one error in find_unbound_irq
Jeremy Fitzhardinge (8):
x86/pci: make sure _PAGE_IOMAP it set on pci mappings
xen: define BIOVEC_PHYS_MERGEABLE()
xen: implement pirq type event channels
x86/io_apic: add get_nr_irqs_gsi()
xen/apic: identity map gsi->irqs
xen: dynamically allocate irq & event structures
xen: statically initialize cpu_evtchn_mask_p
xen/pci: clean up Kconfig a bit
Konrad Rzeszutek Wilk (50):
xen: set pirq name to something useful.
Xen/x86/PCI: Add support for the Xen PCI subsystem
pci/xen: For non-privileged domains, implement a pcibios_enable_irq
(xen_pcifront_enable_irq) function.
pci: Export pci_walk_bus function.
xen: Find an unbound irq number in reverse order (high to low).
xen: Provide a variant of xen_poll_irq with timeout.
xen: Export xen_clear_irq_pending and xen_poll_irq_timeout as the PCI
front module utilizes them.
xen/apic: fix shared irq device passthrough
xen-pci: Take advantage of the shared IRQ flags.
pci/xen: Provide a registration mechanism for the PCI frontend module
functions.
x86: Copy-n-paste arch_teardown_msi_irqs from msi.c to io_apic.c.
pci-xen: Add two new functions to deal with MSI/MSI-X type interrupts.
x86: In PV guest mode, initialize MSI/MSI-X via the pci-front driver.
xen-pci: Add support for MSI destroying of IRQ.
xenbus: Xen paravirtualised PCI hotplug.
xenbus: Add new states to xenbus_strstate()
xenbus: prevent warnings on unhandled enumeration values
xen-pcifront: Initial copy from linux-2.6.18.hg of the pcifront driver.
xen-pcifront: Including the pciif.h header file.
xen-pcifront: Fix include header name change.
xen-pcifront: Fix compile warning: ignoring return value of
'pci_bus_add_device', declared with attribute warn_unused_result
xen-pcifront: Fix compile warning: passing argument 2 of 'pci_walk_bus'
from incompatible pointer type
xen-pcifront: Fix compile error. The bind_to_irq_handler has different
arguments.
xen-pcifront: Fix compile error: implicit declaration of function
'virt_to_mfn'
xen-pcifront: Fix compile error: implicit declaration of function
'clear_evtchn'
xen-pcifront: Fix compile error: implicit declaration of function
'gnttab_end_foreign_access'
xen-pcifront: Fix compile error: too few arguments to function
'gnttab_end_foreign_access'
xen-pcifront: Remove function declerations (CONFIG_PCI_DOMAIN) that exist
in recent kernels.
xen-pcifront: Fix uage of INIT_WORK.
xen-pcifront: Add proper check to see if running under Xen.
xen-pcifront: Improper assumption that event channel == IRQ number.
xen-pcifront: Replace HYPERVISOR_poll with 'xen_poll_irq_timout' function.
xen-pcifront: Coalesce pci.c functions in xenbus.c.
xen-pcifront: Coalesce xen/pcifront.h in drivers/xen/pcifront/pcifront.h
xen-pcifront: Remove ia64 from pcifront.c support.
xen-pcifront: Remove unused pci_bus_sem extern, as we don't use it.
xen-pcifront: Coalesce pcifront.h in xenbus.c.
xen-pcifront: Coalesce pci_op.c in xenbus.c.
xen-pcifront: Remove unnecessary function declerations.
xen-pcifront: Rename the drivers/xen/pcifront/* driver to
drivers/pci/xen-pcifront.c.
xen-pcifront: Change the boot-order of initialising the PCI frontend.
xen-pcifront: Fix warnings/errors reported by checkpatch.pl
xen-pcifront: In xen-pcifront.c updated printk(KERN_ERR ... to dev_err
macro.
xen-pcifront: Have pci_frontend_enable_[msi|msix] save PIRQ values in a
int array.
xen-pcifront: In pci_frontend_disable_msi do not alter the dev->irq.
xen-pcifront: Check pci_claim_resource return value.
xen-pcifront: remove driver_data direct access of struct device
xen-pcifront: Register pci_frontend_[enable|disable]_[msi|msix] functions.
xen-pcifront: Enable Xen PCI front to be compiled as module and also on
x86.
xen-pcifront: Make the driver build only under X86
