* unmodified_drivers: enable unplug per defaultOlaf Hering2013-09-201-1/+7
| | | | | | | | | | | | | Since xen-3.3 an official unplug protocol for emulated hardware is available in the toolstack. The pvops kernel does the unplug per default, so it is safe to do it also in the drivers for forward ported xenlinux. Currently its required to load xen-platform-pci with the module parameter dev_unplug=all, which is cumbersome. Also recognize the dev_unplug=never parameter, which provides the default before this patch. Signed-off-by: Olaf Hering <olaf@aepfle.de>
* unmodified_drivers: remove inclusion of asm/system.hOlaf Hering2012-05-141-1/+0
| | | | | | | | | Allow compilation of PVonHVM drivers with forward-ported xenlinux sources in openSuSE 12.2. Since Linux 3.4 asm/system.h is not present anymore. Remove inclusion of this header, its not needed. Signed-off-by: Olaf Hering <olaf@aepfle.de> Committed-by: Jan Beulich <jbeulich@suse.com>
* unmodified drivers: add pfn_is_ram helper for kdumpOlaf Hering2012-03-161-0/+29
| | | | | | | | | | Register pfn_is_ram helper speed up reading /proc/vmcore in the kdump kernel. It is compiled only if the kernel source is recent enough to have the pfn_is_ram helper (v3.0-rc1, commit 997c136f518c5debd63847e78e2a8694f56dcf90).

* unmodified drivers: hide xen_cpuid_base() in version 2.6.38+Olaf Hering2012-03-161-0/+2
| | | | | | | | | | | | | | | | | | | | Allow compilation of PVonHVM drivers with forward-ported xenlinux sources in openSuSE 12.1. xen_cpuid_base() is now in mainline, the copy in the xen tree leads to a compilation error. The current state leads to a compile error: /usr/src/packages/BUILD/xen-4.2.24547/non-dbg/obj/default/platform-pci/platform-pci.c:121: error: redefinition of 'xen_cpuid_base' /usr/src/linux-3.0.13-0.11/arch/x86/include/asm/xen/hypervisor.h:43: error: previous definition of 'xen_cpuid_base' was here The reason is that the kernel sources are searched before the xen sources for asm/hypervisor.h: /usr/src/linux-3.0.13-0.11/arch/x86/include/asm/hypervisor.h /usr/src/packages/BUILD/xen-4.2.24547/non-dbg/obj/default/include/asm/hypervisor.h Signed-off-by: Olaf Hering <olaf@aepfle.de> Acked-by: Jan Beulich <jbeulich@suse.com> Committed-by: Jan Beulich <jbeulich@suse.com>

| | | | | | | | | | | | | | device This is the correct interface to use and something has broken the use of the previous incorrect interface (which fails because the request conflicts with the resources assigned for the PCI device itself instead of nesting like the PCI interfaces do). pci_request_region() has been available since at least Linux 2.6.5.

* x86, hvm: Hyper-V guest interface support with small set of enlightenmentsKeir Fraser2008-10-141-23/+28
| | | | | | | | | | | | | A minimal implementation of the Viridian (Hyper-V) guest interface. The only enlightenments advertised and supported are vAPIC MSRs and long-spin-wait notifications. The set of enlightenments can easily be extended in future, as they are found to provide a performance win, and configured via an extended HVM_PARAM_VIRIDIAN hvm parameter.

* pv-on-hvm: Signal crash to Xen tools when HVM guest panics.Keir Fraser2008-02-131-0/+4
| | | | | | | | | | | | | | | | | Attached patch adds a function to automatically dump core file when guest linux on HVM domain panics, in the same way as PV domain. I tested this patch with kernel 2.6.9 and 2.6.18 on both of x86 and ia64 (to buid for ia64, some patches in the ia64 tree are needed) by the following steps, and confirmed it works well: 1. Build xen-platform-pci.ko. 2. In /etc/xen/xend-config.sxp, set (enable-dump yes). 3. On guest linux, execute insmod: # insmod xen-platform-pci.ko 4. When guest linux panics, a core file is dumped.

* pv-on-hvm: fixes for unmodified drivers build and modern LinuxKeir Fraser2007-10-251-0/+4
| | | | | | | | | | | | | | | | | | - The adjustments to README and overrides.mk are generic. - The removal of explicit linux/config.h inclusion should also not cause any issues. - The introduction of irq_handler_t should eliminiate warnings on 2.6.19+ kernels (I didn't check they're there, but since the request_irq prototype changed, I'm sure there's at least one. However, as a result changes to the Linux tree are expected to be required. - The change setup_xen_features -> xen_setup_features follows the naming in mainline 2.6.23 but would apparently also require changes to the Linux tree. - The changes SA_* -> IRQF_ and pci_module_init -> pci_register_driver should also not cause issues.
