Message-Id: <1292263303-31680-1-git-send-email-konrad.wilk@oracle.com> Date: Mon, 13 Dec 2010 13:01:34 -0500 From: Konrad Rzeszutek Wilk <konrad.wilk@...cle.com> To: xen-devel@...ts.xensource.com Cc: Jan Beulich <JBeulich@...ell.com>, linux-kernel@...r.kernel.org, Jeremy Fitzhardinge <jeremy@...p.org>, Konrad Rzeszutek Wilk <konrad@...nel.org>, Stefano Stabellini <stefano.stabellini@...citrix.com> Subject: [PATCH v2] Xen PCI backend driver. Attached is set of patches for the Xen PCI backend driver. Lot of driver pieces have been reviewed in the past, but I don't recall it being sent to xen-devel. The infrastructure parts (patches #1-#6) were posted at some point. The Xen PCI back driver patch (#7) was squished from the git tree (devel/xen-pciback-0.2) as some of them were just boring (supporting 2.6.18 driver to work, checkpatch), and some already posted/reviewed. The full tree is available at: git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git devel/xen-pciback-0.2 .. and that is the tree I will use when asking Linus to pull the driver. So what is Xen PCI backend? It is a simple driver that utilizes the ring-buffer to exchange 0xcf8 inb/outb commands from the guest to the control domain. The backend carries out sanitized PCI configuration reads/writes on behest of the guest. It also has some extra commands for enabling/disabling MSI/MSI-X interrupts. Please take a look at the patches (or even just a couple of them) and provide feedback. The patch set depends on stable/xenbus, which is back-port of XenBus backend driver done by Ian Campbell. A merge of this tree along with stable/xenbus is available as: git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git master The diffstat: arch/x86/include/asm/xen/pci.h | 16 + arch/x86/pci/xen.c | 73 ++ drivers/xen/Kconfig | 65 ++ drivers/xen/Makefile | 1 + drivers/xen/events.c | 68 ++- drivers/xen/pciback/Makefile | 17 + drivers/xen/pciback/conf_space.c | 435 +++++++ drivers/xen/pciback/conf_space.h | 126 +++ drivers/xen/pciback/conf_space_capability.c | 66 ++ drivers/xen/pciback/conf_space_capability.h | 26 + drivers/xen/pciback/conf_space_capability_msi.c | 111 ++ drivers/xen/pciback/conf_space_capability_pm.c | 113 ++ drivers/xen/pciback/conf_space_capability_vpd.c | 40 + drivers/xen/pciback/conf_space_header.c | 385 +++++++ drivers/xen/pciback/conf_space_quirks.c | 140 +++ drivers/xen/pciback/conf_space_quirks.h | 35 + drivers/xen/pciback/controller.c | 442 ++++++++ drivers/xen/pciback/passthrough.c | 178 +++ drivers/xen/pciback/pci_stub.c | 1371 +++++++++++++++++++++++ drivers/xen/pciback/pciback.h | 142 +++ drivers/xen/pciback/pciback_ops.c | 241 ++++ drivers/xen/pciback/slot.c | 191 ++++ drivers/xen/pciback/vpci.c | 244 ++++ drivers/xen/pciback/xenbus.c | 726 ++++++++++++ include/xen/events.h | 9 + 25 files changed, 5258 insertions(+), 3 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
