  commit c4e5cc2ccc5b8274d02f7855c4769839989bb349
  Author: Roger Pau Monné 
  Date:   Thu Sep 29 14:44:10 2022 +0200
  
  x86/ept: limit calls to memory_type_changed()
  
  memory_type_changed() is currently only implemented for Intel EPT, and
  results in the invalidation of EMT attributes on all the entries in
  the EPT page tables.  Such invalidation causes EPT_MISCONFIG vmexits
  when the guest tries to access any gfns for the first time, which
  results in the recalculation of the EMT for the accessed page.  The
  vmexit and the recalculations are expensive, and as such should be
  avoided when possible.
  
  Remove the call to memory_type_changed() from
  XEN_DOMCTL_memory_mapping: there are no modifications of the
  iomem_caps ranges anymore that could alter the return of
  cache_flush_permitted() from that domctl.
  
  Encapsulate calls to memory_type_changed() resulting from changes to
  the domain iomem_caps or ioport_caps ranges in the helpers themselves
  (io{ports,mem}_{permit,deny}_access()), and add a note in
  epte_get_entry_emt() to remind that changes to the logic there likely
  need to be propagaed to the IO capabilities helpers.
  
  Note changes to the IO ports or memory ranges are not very common
  during guest runtime, but Citrix Hypervisor has an use case for them
  related to device passthrough.

  commit 918b8842a852e0e7446286f546724b1c63c56c66
  Author: Michal Orzel 
  Date:   Mon Jul 5 08:39:52 2021 +0200
  
  arm64: Change type of hsr, cpsr, spsr_el1 to uint64_t
  
  AArch64 registers are 64bit whereas AArch32 registers
  are 32bit or 64bit. MSR/MRS are expecting 64bit values thus
  we should get rid of helpers READ/WRITE_SYSREG32
  in favour of using READ/WRITE_SYSREG.
  We should also use register_t type when reading sysregs
  which can correspond to uint64_t or uint32_t.
  Even though many AArch64 registers have upper 32bit reserved
  it does not mean that they can't be widen in the future.
  
  Modify type of hsr, cpsr, spsr_el1 to uint64_t.
  Previously we relied on the padding after spsr_el1.
  As we removed the padding, modify the union to be 64bit so we don't 
corrupt spsr_fiq.
  No need to modify the assembly code because the accesses were based on 
64bit
  registers as there was a 32bit padding after spsr_el1.
  
  Remove 32bit padding in cpu_user_regs before spsr_fiq
  as it is no longer needed due to upper union being 64bit now.
  Add 64bit padding in cpu_user_regs before spsr_el1
  because the kernel frame should be 16-byte aligned.
  
  Change type of cpsr to uint64_t in the public outside interface
  "public/arch-arm.h" to allow ABI compatibility between 32bit and 64bit.
  Increment XEN_DOMCTL_INTERFACE_VERSION.
  
  Change type of cpsr to uint64_t in the public outside interface
  "public/vm_event.h" to allow ABI compatibility between 32bit and 64bit.

  commit ced9795c6cb4165b6d231a732e5351933dbd8b38
  Author: Jan Beulich 
  Date:   Fri Jan 15 16:03:56 2021 +0100
  
  mm: split out mfn_t / gfn_t / pfn_t definitions and helpers
  
  xen/mm.h has heavy dependencies, while in a number of cases only these
  type definitions are needed. This separation then also allows pulling in
  these definitions when including xen/mm.h would cause cyclic
  dependencies.
  
  Replace xen/mm.h inclusion where possible in include/xen/. (In
  xen/iommu.h also take the opportunity and correct the few remaining
  sorting issues.)
  
  While the change could be dropped, remove an unnecessary asm/io.h
  inclusion from xen/arch/x86/acpi/power.c. This was the initial attempt
  to address build issues with it, until it became clear that the header
  itself needs adjustment.

  commit f89955449c5a47ff688e91873bbce4c3670ed9fe

  tools/init-xenstore-domain: support xenstore pvh stubdom
  
  Instead of creating the xenstore-stubdom domain first and parsing the
  kernel later do it the other way round. This enables to probe for the
  domain type supported by the xenstore-stubdom and to support both, pv
  and pvh type stubdoms.
  
  Try to parse the stubdom image first for PV support, if this fails use
  HVM. Then create the domain with the appropriate type selected.

  commit 1b3cec69bf300e012a0269f0a4f28cca1ebf22c9
  Author: Andrew Cooper 
  Date:   Wed Feb 5 15:25:21 2020 +
  
  tools/libxl: Combine legacy CPUID handling logic
  
  While we are in the process of overhauling boot time CPUID/MSR handling, 
the
  existing logic is going to have to remain in roughly this form for 
backwards
  compatibility.
  
  Fold libxl__cpuid_apply_policy() and libxl__cpuid_set() together into a 
single
  libxl__cpuid_legacy() to reduce the complexity for callers.
  
  No functional change.

  commit ea22bcd030da771be18821bf4a898ed7a314eb83
  Author: Alexandru Stefan ISAILA 
  Date:   Fri Jan 17 13:31:30 2020 +
  
  x86/altp2m: Add hypercall to set a range of sve bits
  
  By default the sve bits are not set.
  This patch adds a new hypercall, xc_altp2m_set_supress_ve_multi(),
  to set a range of sve bits.
  The core function, p2m_set_suppress_ve_multi(), does not break in case
  of a error and it is doing a best effort for setting the bits in the
  given range. A check for continuation is made in order to have
  preemption on large ranges.
  The gfn of the first error is stored in
  xen_hvm_altp2m_suppress_ve_multi.first_error_gfn and the error code is
  stored in xen_hvm_altp2m_suppress_ve_multi.first_error.
  If no error occurred the values will be 0.

  IRQ: u16 is too narrow for an event channel number
  
  FIFO event channels allow ports up to 2^17, so we need to use a wider
  field in struct pirq. Move "masked" such that it may share the 8-byte
  slot with struct arch_pirq on 64-bit arches, rather than leaving a
  7-byte hole in all cases.
  
  Take the opportunity and also add a comment regarding "arch" placement
  within the structure.

  livepatch: Add metadata runtime retrieval mechanism
  
  Extend the livepatch list operation to fetch also payloads' metadata.
  This is achieved by extending the sysctl list interface with 2 extra
  guest handles:
  * metadata - an array of arbitrary size strings
  * metadata_len - an array of metadata strings' lengths (uin32_t each)
  
  Payloads' metadata is a string of arbitrary size and does not have an
  upper bound limit. It may also vary in size between payloads.
  
  In order to let the userland allocate enough space for the incoming
  data add a metadata total size field to the list sysctl operation and
  fill it with total size of all payloads' metadata.
  
  Extend the libxc to handle the metadata back-to-back data transfers
  as well as metadata length array data transfers.
  
  The xen-livepatch userland tool is extended to always display the
  metadata for each received module. The metadata is received with the
  following format: key=value\0key=value\0...key=value\0. The format is
  modified to the following one: key=value;key=value;...key=value.
  The new format allows to easily parse the metadata for a given module
  by a machine.

  livepatch: Handle arbitrary size names with the list operation
  
  The payloads' name strings can be of arbitrary size (typically small
  with an upper bound of XEN_LIVEPATCH_NAME_SIZE).
  Current implementation of the list operation interface allows to copy
  names in the XEN_LIVEPATCH_NAME_SIZE chunks regardless of its actual
  size and enforces space allocation requirements on userland tools.
  
  To unify and simplify the interface, handle the name strings of
  arbitrary size by copying them in adhering chunks to the userland.
  In order to let the userland allocate enough space for the incoming
  data add an auxiliary interface xc_livepatch_list_get_sizes() that
  provides the current number of payload entries and the total size of
  all name strings. This is achieved by extending the sysctl list
  interface with an extra fields: name_total_size.
  
  The xc_livepatch_list_get_sizes() issues the livepatch sysctl list
  operation with the nr field set to 0. In this mode the operation
  returns the number of payload entries and calculates the total sizes
  for all payloads' names.
  When the sysctl operation is issued with a non-zero nr field (for
  instance with a value obtained earlier with the prior call to the
  xc_livepatch_list_get_sizes()) the new field name_total_size provides
  the total size of actually copied data.
  
  Extend the libxc to handle the name back-to-back data transfers.
  
  The xen-livepatch tool is modified to start the list operation with a
  call to the xc_livepatch_list_get_sizes() to obtain the actual

  libxl: Make libxl_domain_unpause async
  
  libxl_domain_unpause needs to make QMP calls, which are asynchronous,
  change the API to reflect that.
  
  Do the same with libxl_domain_pause async, even if it will keep
  completing synchronously.
  
  Also fix some coding style issue in those functions.

  config: don't hardcode toolchain binaries
  
  Currently the names of the build toolchain binaries are hardcoded in
  StdGNU.mk, and the values from the environment are ignored.
  
  Switch StdGNU.mk to use '?=' instead of '=', so that values from the
  environment are used if present, else default to the values provided
  by the config file.
  
  This change fixes the gitlab CI loop, that was relying on passing
  custom values in the environment variables for the compiler and the
  linker.

  commit 03957f58db8942d61f4889b6924e39d3b27a9e43
  Author: Julien Grall 
  Date:   Tue May 14 13:24:38 2019 +0100
  
  xen/const: Extend the existing macro BIT to take a suffix in parameter
  
  Arm currently provides two macro BIT and BIT_ULL that are only usable
  in C and return respectively unsigned long and unsigned long long.
  
  Extending the macros to deal with assembly would be a nice benefits as
  it could replace the common pattern to define fields (AC(1, sfx) << X)
  easier to read.
  
  Rather than extending the two macros, it was decided to drop BIT_ULL()
  and extend the macro BIT() to take a suffix (e.g U, UL, ULL) in
  parameter. This would allow to use different suffix without having to
  define new macros.
  
  The new extend macro is now moved in include/xen/const.h so it can be
  used by anyone in Xen and also avoid to include bitops.h in assembly
  code.

  commit e9be34be5f9a1a6ecbf05ba9502cd705ae441476
  Author: Roger Pau Monné 
  Date:   Tue Oct 9 16:27:13 2018 +0200
  
  x86/vtd: fix iommu_share_p2m_table
  
  Commit 2916951c1 "mm / iommu: include need_iommu() test in
  iommu_use_hap_pt()" changed the check in iommu_share_p2m_table to use
  need_iommu(d) (as part of iommu_use_hap_pt) instead of iommu_enabled,
  which broke the check because at the point in domain construction
  where iommu_share_p2m_table is called need_iommu(d) will always return
  false.
  
  Fix this by reverting to the previous logic.
  
  While there turn the hap_enabled check into an ASSERT, since the only
  caller of iommu_share_p2m_table already performs the hap_enabled check
  before calling the function.

  tools/libxl: Drop xc_domain_configuration_t from libxl__domain_build_state
  
  The data it stores is initialised and exclusively used within
  libxl__domain_make(), with the important details written back elsewhere by
  libxl__arch_domain_save_config().  Prepare xc_config on 
libxl__domain_make()'s
  stack, and drop the parameter.

   tools: detect appropriate debug optimization level
   
   When building debug use -Og as the optimization level if its 
 available,
   otherwise retain the use of -O0. -Og has been added by GCC to enable 
 all
   optimizations that to not affect debugging while retaining full
   debugability.

Agreed. But the compiler used by osstest won't be changing any time soon
to pick up fixes.

What would the ARM maintainers like me to do? Initialize it to 0 at the top?

I agree with your opinion in general.

In this particular case, I think the compiler is to be blamed. p2m_size
should have been initialised in a previous loop by the time the code
comes to the place gcc complained.

We really should be build testing things at all optimisation levels.  We
should be ashamed that -O3 gives build failures in most of our major
components.  (This is yet another item on my TODO list which I've not
had time to complete.)

Sadly altering optimization levels always has the potential of
triggering issues like this:

xc_dom_arm.c: In function 'meminit':
xc_dom_arm.c:446:5: error: 'p2m_size' may be used uninitialized in this 
function [-Werror=maybe-uninitialized]

  tools: detect appropriate debug optimization level
  
  When building debug use -Og as the optimization level if its available,
  otherwise retain the use of -O0. -Og has been added by GCC to enable all
  optimizations that to not affect debugging while retaining full
  debugability.

  commit 340edc3902c1757a0e1f4391930366fb25a05df3
  Author: Andrew Cooper 
  Date:   Tue Feb 27 16:48:19 2018 +
  
  xen/sched: Improvements to the {alloc,free}_domdata() interfaces
  
  The main purpose of this change is for the subsequent cleanup it enables, 
but
  it stands on its own merits.
  
  In principle, these hooks are optional, but the SCHED_OP() default 
aliases a
  memory allocation failure, which causes arinc653 to play the dangerous 
game of
  passing its priv pointer back, and remembering not to actually free it.
  
  Redefine alloc_domdata to use ERR_PTR() for errors, NULL for nothing, and
  non-NULL for a real allocation, which allows the hook to become properly
  optional.  Redefine free_domdata to be idempotent.
  
  For arinc653, this means the dummy hooks can be dropped entirely.  For the
  other schedulers, this means returning ERR_PTR(-ENOMEM) instead of NULL 
for
  memory allocation failures, and modifying the free hooks to cope with a 
NULL
  pointer.  While making the alterations, drop some spurious casts to void 
*.
  
  Introduce and use proper wrappers for sched_{alloc,free}_domdata().  
These are
  strictly better than SCHED_OP(), as the source code is visible to
  grep/cscope/tags, the generated code is better, and there can be proper
  per-hook defaults and checks.
  
  Callers of the alloc hooks are switched to using IS_ERR(), rather than
  checking for NULL.
