* 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: handle IRQF_SAMPLE_RANDOMOlaf Hering2012-09-101-1/+5
| | | | | | | | | | The flag IRQF_SAMPLE_RANDOM was removed in 3.6-rc1. Add it only if it is defined. An additional call to add_interrupt_randomness is appearently not needed because its now called unconditionally in handle_irq_event_percpu().

* 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.

| | | | | | | | | | The forward ported xenlinux sources in openSuSE 12.2 were switched from the old synch_bitops to the sync_bitops since kernel version 3.3. Add compat macros to use either old or new helpers depending on used kernel source version. Signed-off-by: Jan Beulich <jbeulich@suse.com> Signed-off-by: Olaf Hering <olaf@aepfle.de>

| | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | - 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.
