* libxl,xl: add max_event_channels option to xl configuration fileDavid Vrabel2013-10-141-0/+11
| | | | | | | | | | | | | | | | | | | Add the 'max_event_channels' option to the xl configuration file to limit the number of event channels that domain may use. Plumb this option through to libxl via a new libxl_build_info field and call xc_domain_set_max_evtchn() in the post build stage of domain creation. A new LIBXL_HAVE_BUILDINFO_EVENT_CHANNELS #define indicates that this new field is available. The default value of 1023 limits the domain to using the minimum amount of global mapping pages and at most 5 xenheap pages.

* xl: update the manpage about "cpus=" and NUMA node-affinityDario Faggioli2013-10-101-7/+15
| | | | | | | | | | | | | | | Since d06b1bf169a01a9c7b0947d7825e58cb455a0ba5 ('libxl: automatic placement deals with node-affinity') it is no longer true that, if no "cpus=" option is specified, xl picks up some pCPUs by default and pin the domain there. In fact, it is the NUMA node-affinity that is affected by automatic placement, not vCPU to pCPU pinning. Update the xl config file documenation accordingly, as it seems to have been forgotten at that time.

* x86/microcode: Scan the initramfs payload for microcode blobKonrad Rzeszutek Wilk2013-09-271-3/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Linux kernel is able to update the microcode during early bootup via inspection of the initramfs blob to see if there is an cpio image with certain microcode files. Linux is able to function with two (or more) cpio archives in the initrd b/c it unpacks all of the cpio archives. The format of the early initramfs is nicely documented in Linux's Documentation/x86/early-microcode.txt: Early load microcode ==================== By Fenghua Yu <fenghua.yu@intel.com> Kernel can update microcode in early phase of boot time. Loading microcode early can fix CPU issues before they are observed during kernel boot time. Microcode is stored in an initrd file. The microcode is read from the initrd file and loaded to CPUs during boot time. The format of the combined initrd image is microcode in cpio format followed by the initrd image (maybe compressed). Kernel parses the combined initrd image during boot time. The microcode file in cpio name space is: kernel/x86/microcode/GenuineIntel.bin During BSP boot (before SMP starts), if the kernel finds the microcode file in the initrd file, it parses the microcode and saves matching microcode in memory. If matching microcode is found, it will be uploaded in BSP and later on in all APs. The cached microcode patch is applied when CPUs resume from a sleep state. There are two legacy user space interfaces to load microcode, either through /dev/cpu/microcode or through /sys/devices/system/cpu/microcode/reload file in sysfs. In addition to these two legacy methods, the early loading method described here is the third method with which microcode can be uploaded to a system's CPUs. The following example script shows how to generate a new combined initrd file in /boot/initrd-3.5.0.ucode.img with original microcode microcode.bin and original initrd image /boot/initrd-3.5.0.img. mkdir initrd cd initrd mkdir kernel mkdir kernel/x86 mkdir kernel/x86/microcode cp ../microcode.bin kernel/x86/microcode/GenuineIntel.bin find .|cpio -oc >../ucode.cpio cd .. cat ucode.cpio /boot/initrd-3.5.0.img >/boot/initrd-3.5.0.ucode.img As such this code inspects the initrd to see if the microcode signatures are present and if so updates the hypervisor. The option to turn this scan on/off is gated by the 'ucode' parameter. The options are now: 'scan' Scan for the microcode in any multiboot payload. <index> Attempt to load microcode blob (not the cpio archive format) from the multiboot payload number. This option alters slightly the 'ucode' parameter by only allowing either parameter: ucode=[<index>|scan] Implementation wise the ucode_blob is defined as __initdata. That is OK from the viewpoint of suspend/resume as the the underlaying architecture microcode (microcode_intel or microcode_amd) end up saving the blob in 'struct ucode_cpu_info' which is a per-cpu data structure (see ucode_cpu_info). They end up saving it when doing the pre-SMP (for CPU0) and SMP (for the rest) microcode loading. Naturally if one does a hypercall to update the microcode and it is newer, then the old per-cpu data is replaced.

* ARM: parse separate DT properties for different commandlinesAndre Przywara2013-09-171-1/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we use the chosen/bootargs property as the Xen commandline and rely on xen,dom0-bootargs for Dom0. However this brings issues with bootloaders, which usually build bootargs by bootscripts for a Linux kernel - and not for the entirely different Xen hypervisor. Introduce a new possible device tree property "xen,xen-bootargs" explicitly for the Xen hypervisor and make the selection of which to use more fine grained: - If xen,xen-bootargs is present, it will be used for Xen. - If xen,dom0-bootargs is present, it will be used for Dom0. - If xen,xen-bootargs is _not_ present, but xen,dom0-bootargs is, bootargs will be used for Xen. Like the current situation. - If no Xen specific properties are present, bootargs is for Dom0. - If xen,xen-bootargs is present, but xen,dom0-bootargs is missing, bootargs will be used for Dom0. The aim is to allow common bootscripts to boot both Xen and native Linux with the same device tree blob. If needed, one could hard-code the Xen commandline into the DTB, leaving bootargs for Dom0 to be set by the (non Xen-aware) bootloader. I will send out a appropriate u-boot patch, which writes the content of the "xen_bootargs" environment variable into the xen,xen-bootargs dtb property.

Xen knows how to emulate it, but unfortunately %xmm3 is 16 bytes long, and the interface between Xen and qemu at the moment would appear to only allow MMIO accesses of 8 bytes.

* xl: Fix 'free_memory' to include outstanding_claims value.Konrad Rzeszutek Wilk2013-04-162-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Updating to make it clear that free_memory reported by 'xl info' is influenced by the outstanding claim value. That is the free memory that will be available to the host once all outstanding claims have been completed. This modifies the behavior that the patch titled "xl: 'xl info' print outstanding claims if enabled (claim_mode=1 in xl.conf)" had - which reported the outstanding claims and nothing else. The free_pages as reported by the hypervisor is the currently available count of pages on the heap. The outstanding pages is the total amount of pages reserved for guests (so not taken from the heap yet). As guests are being populated the memory from the heap shrinks and the outstanding count of pages decreases. The total memory used for guests increases. As the available count of pages on the heap and outstanding claims are intertwined, report the amount of free memory available to be a combination of that. That is free heap memory minus the outstanding pages. We also make some odd choices in reporting. By default we will only display 'outstanding_claims' if the claim_mode is enabled in the global configuration file. However, if there are outstanding claims, we will ignore the claim_mode and report these values.
