- Martin Osterloh
Notes
This is a list of the current (09/25/2015) Xen 4.3.4 patch queue. This should work well as a starting point for upgrading Xen to 4.6.x.
Backports
bp-ept-update-aa9114edd97b292cd89b3616e3f2089471fd220.patch
Adds passing of vpu and domain for various MTRR type setting in hvm_msr_write_intercept(). Also added EXIT_REASON_EPT_MISCONFIG exit handler.
HVM Support
hvmloader_print_e820.patch
Support for e820 printing.
hvmloader-vga-command-io.patch
Enable IO since VGA needs it.
hvm-pm-hibernate-s-state.patch
Changed PM1a_CNT.SLP_TYP and PM1b_CNT.SLP_TYP from 0x0 to 0x6 definition block to mach piix emulation.
hvm-pm-s-states.patch
Adds xc_set_hvm_pio() and corresponding do_hvm_op() case. Added SCI_MASK which masks off bits in PM1a_STS that can generate an SCI. Added int pm_pio_set().
hvm-rtc.patch
Updates guest domains real-time clock
hvm-rtc-refresh-time.patch
Refreshes current time via gmtime()
General/Graphic Pass-Through
gpt-igd-hp-resume-workaround.patch
workaround host S3 resume issue on HP laptops. Turns out saving iGfx bars during iommu suspend and restoring them in iommu resume will fix the hang/reset during host resume on HP laptops. Following does that as a fallback on systems that doesn't have the firmware fix to save/restore iGfx bars.
gpt-iommu-mapping.patch
Add hypercalls for iommu mapping (iommu_map_batch, iommu_x_mapping).
gpt-nvidia.patch
For NVIDIA VGA cards load std vga BIOS image
gpt-quiet-log.patch
comments out print statement
gpt-s3-resume-reason.patch
Set power button status (necessary for proper win32 resume). Additionally,set rsm/wak_sts bit. set rsm/wak_sts bit.
gpt-superblanker.patch
16M for superblanker FB. e820 address = 0xfd000000, type = E820_RESERVED.
ACPI emulation/ pass-through
acpi-no-hotplug.patch
Remove pci hotplug from ACPI DSDT tables (_EJ0).
prune-acpi-devices.patch
Comments out name decoding for FD and SPKR.
prune-vga-acpi-dev.patch
(Presumably) removed support for VGA S3 suspend/resume work in Windows XP/2003.
qemu-acpi-tables.patch
Makefile lists qemu_utils.c as source file. "Fixes" up ACPI headers. Added population of Qemu tables.
Hypercalls
xc-xt-allow-pat-cacheattrs-for-all-domains.patch
Allows PAT cache attributes for all domains.
xc-xt-aperture-map.patch
Add an hypercall to map guest pages within an aperture in its own address space (modifying the p2m).

Make cpuid ours: Hide core/HT topology, make vcpu appear as multicores, leave FEATURE_MWAIT, put our signature.
xc-xt-ept-respect-cacheattr-pin.patch
Ignore PAT memory type for cache-pinned pages.
xc-xt-foreign-batch-cacheattr.patch
Implement translation of a list of gpfn to a list of mfn in new hypercalls: XENMEM_translate_gpfn_list & XENMEM_release_mfn_list. Typically used to get framebuffer's mfns of the gpfns we receive from the graphic emulation (ioemu/xengfx).

Huge patch. Added functionality to read from VHDs. This thing is huge.
blktap2-vci.patch
This is huge as well. Lots of handling special cases for Windows.
blktap-instrumentation.patch
Tapdisk control instrumentation such as read(), write(), select().
blktap-quieten-udevd.patch

Misc Patches
10ms_timeslice.patch
changes the timeslice to 10ms from previously 30ms.
add-command-line-option-to-disable-arat.patch
Added command line option to force ARAT (Always Running APIC TIMER) to off.
add-percentages-to-xenpm.patch
Added eprcent-wise printing in print_cx_stat().
add_system_time_timestamps.patch
console_us_timestamps: include a microsecond (us) timestamp prefix on every Xen console line.
cpufreq_gov_stop_avoid_panic.patch
Checking for if this domain info enables CPUFREQ_GOV_STOP. If so, the timer exits.
crash_flag_hypercall.patch
Adds crash flag to hypercalls.
dom0_auto_mem.patch
Added maximum increase amount of pages for dom0.
evtchn-do-not-set-pending-if-s3.patch
If domain is in S3 it will miss the notification, so check here.
fix-32bit-xsm-interface.patch
Added XEN_GUEST_HANDLE and its 64-bit equivalent.
fix-memcpy-in-x86-emulate.patch
Routine to make __hvm_copy appropriate to use for copying the results of instruction emulation back to guest memory - these typically require 64-bit, 32-bit and 16-bit writes to be atomic whereas memcpy is only atomic for 64-bit writes. This is still not 100% correct since copies larger than 64-bits will not be atomic for the last 2-6 bytes but should be good enough for instruction emulation.
fix-pci-serial-hang.patch
Fix for ns16550 chipset. IO seems to be wonky for that particular set of hardware.
fix-race-between-udev-and-tapctl.patch
Fixes race condition between udev and tapctl.
fix-write-clash.patch
Added undef's for READ and WRITE to shut the compiler up.
fix-xenctrl-enum-defn.
Moved definition of enum xc_error_code from xenctrl.h.

Processing dmsg in increments.
iobitmap-on-all-vcpus.patch
Per VCPU bitmap setting.
large-remap.patch
Map into the current process the range of guest pages given by [pfn:pfn+num-1]. Mapping does not fail if some pages cannot be mapped. Instead we indicate any pages that cannot be mapped by setting the corresponding bit in err_bits.
libvhd-disable-static-batmaps.patch
Commented out all static use of VCI batmaps.
local-ipxe.patch
Patched Makefile to use local ipxe file.
microcode-info.patch
pr_debug macro defined to actually do something (i.e. printing)
publish_xentrace_formats.patch
Xentrace Makefile expanded to make its own directory and place files.
reboot-quirk-pci.patch
Added handling for rebooting over PCI. Specifically, added handling of CF9 "PCI reset register".

Added sanity check to see if the end address is smaller than the base address. If so, print message
and return -EINVAL.
rombios-faster.patch
Changed number of BX_MAX_ATA_INTERFACES from 4 to two and BX_MAX_ATA_DEVICES to 3.
sb_reboot_turbo_workaround.patch
Added definition for MSR_SB_TURBO_CURRENT_LIMIT to be 0x000001ac.

workaround-nehalem-igd-vtd.patch
Workaround fixing VT-d breakage on Clarkdale integrated graphics!
xen-allow-hvm.patch
Allow HVM operation at all times, otherwise hvm_enable will be off if we boot without TBOOT and TXT is enabled in the BIOS.
xen-cpuidle-hang.patch
Added get-max-cstate regarding the current C-state limitation. Added check to verify that dom0 is NOT using RTC interrupts.
xen-libhvm.patch
Patches helepr library for reading ACPI and SMBIOS firmware values from the host system for use with the HVM guest firmware pass-through feature in Xen.
xenstored-instrumentation.patch
Ignore noisy messages unless verbose specified.
xentrace-format-handle-zero-tsc.patch
