misc: remove DEFINE_PCI_DEVICE_TABLE usage

2014-07-18T23:54:23+00:00

Removes DEFINE_PCI_DEVICE_TABLE from drivers/misc/genwqe/card_base.c,
drivers/misc/genwqe/card_base.c, and drivers/misc/vmw_vmci/vmci_guest.c
in preferance of a "real" structure definition.

vmw_vmci: Use pci_enable_msix_exact() instead of pci_enable_msix()

2014-02-28T23:24:32+00:00

As result of deprecation of MSI-X/MSI enablement functions
pci_enable_msix() and pci_enable_msi_block() all drivers
using these two interfaces need to be updated to use the
new pci_enable_msi_range()  or pci_enable_msi_exact()
and pci_enable_msix_range() or pci_enable_msix_exact()
interfaces.

VMCI: fix error handling path when registering guest driver

2014-01-10T00:16:15+00:00

When host capabilities check failed or when we were unable to register doorbell
bitmap we were forgetting to set error code and were returning 0 which would
make upper layers believe that probe was successful.

vmw_vmci: Convert driver to use get_user_pages_fast()

2013-10-06T01:04:55+00:00

Convert vmci_host_setup_notify() and qp_host_get_user_memory() to use
get_user_pages_fast() instead of get_user_pages(). Note that
qp_host_get_user_memory() was using mmap_sem for writing without an
apparent reason.

VMCI: fix to pass correct device identity to free_irq()

2013-09-26T20:47:36+00:00

free_irq() expects the same device identity that was passed to
corresponding request_irq(), otherwise the IRQ is not freed.

VMCI: Add support for virtual IOMMU

2013-08-28T04:42:12+00:00

This patch adds support for virtual IOMMU to the vmci module.  We switch
to DMA consistent mappings for guest queuepair and doorbell pages that
are passed to the device.  We still allocate each page individually,
since there's no guarantee that we'll get a contiguous block of physical
for an entire queuepair (especially since we allow up to 128 MiB!).

Also made the split between guest and host in the kernelIf struct much
clearer.  Now it's obvious which fields are which.

VMCI: Remove non-blocking/pinned queuepair support

2013-08-28T04:42:12+00:00

We added this for a special case that doesn't exist on Linux.  Remove
the non-blocking/pinned queuepair code and simplify the driver in
preparation for adding virtual IOMMU support.

Hoist memcpy_fromiovec/memcpy_toiovec into lib/

2013-05-20T00:54:22+00:00

ERROR: "memcpy_fromiovec" [drivers/vhost/vhost_scsi.ko] undefined!

That function is only present with CONFIG_NET.  Turns out that
crypto/algif_skcipher.c also uses that outside net, but it actually
needs sockets anyway.

In addition, commit 6d4f0139d642c45411a47879325891ce2a7c164a added
CONFIG_NET dependency to CONFIG_VMCI for memcpy_toiovec, so hoist
that function and revert that commit too.

socket.h already includes uio.h, so no callers need updating; trying
only broke things fo x86_64 randconfig (thanks Fengguang!).

misc/vmw_vmci: Add dependency on CONFIG_NET

2013-04-03T18:53:39+00:00

Building the vmw_vmci driver with CONFIG_NET undefined results in:

drivers/built-in.o: In function `__qp_memcpy_from_queue.isra.13':
vmci_queue_pair.c:(.text+0x1671a8): undefined reference to `memcpy_toiovec'
drivers/built-in.o: In function `__qp_memcpy_to_queue.isra.14':
vmci_queue_pair.c:(.text+0x167341): undefined reference to `memcpy_fromiovec'
make[1]: [vmlinux] Error 1 (ignored)

since memcpy_toiovec and memcpy_fromiovec are defined in the networking code.
Add the missing dependency.

VMCI: Fix process-to-process DRGAMs.

2013-03-15T19:58:12+00:00

When sending between processes, we always schedule a work item.  Our work info
struct has the message embedded in the middle, which means that we end up
overwriting subsequent fields when we copy the (variable-length) message into
it.  Move it to the end of the struct.
