Tobias Röhmel 910e4f2497 target/arm: Make RVBAR available for all ARMv8 CPUs
RVBAR shadows RVBAR_ELx where x is the highest exception
level if the highest EL is not EL3. This patch also allows
ARMv8 CPUs to change the reset address with
the rvbar property.

Tobias Röhmel c7f786abe2 target/arm: Don't add all MIDR aliases for cores that implement PMSA
Cores with PMSA have the MPUIR register which has the
same encoding as the MIDR alias with opc2=4. So we only
add that alias if we are not realizing a core that
implements PMSA.

Peter Maydell 9e65f4e6da target/arm:Set lg_page_size to 0 if either S1 or S2 asks for it
In get_phys_addr_twostage() we set the lg_page_size of the result to
the maximum of the stage 1 and stage 2 page sizes.  This works for
the case where we do want to create a TLB entry, because we know the
common TLB code only creates entries of the TARGET_PAGE_SIZE and
asking for a size larger than that only means that invalidations
invalidate the whole larger area.  However, if lg_page_size is
smaller than TARGET_PAGE_SIZE this effectively means "don't create a
TLB entry"; in this case if either S1 or S2 said "this covers less
than a page and can't go in a TLB" then the final result also should
be marked that way.  Set the resulting page size to 0 if either
stage asked for a less-than-a-page entry, and expand the comment
to explain what's going on.

This has no effect for VMSA because currently the VMSA lookup always
returns results that cover at least TARGET_PAGE_SIZE; however when we
add v8R support it will reuse this code path, and for v8R the S1 and
S2 results can be smaller than TARGET_PAGE_SIZE.

Thomas Huth cb9c6a8e5a .gitlab-ci.d/windows: Work-around timeout and OpenGL problems of the MSYS2 jobs
The windows jobs (especially the 32-bit job) recently started to
hit the timeout limit. Bump it a little bit to ease the situation
(80 minutes is quite long already - OTOH, these jobs do not have to
wait for a job from the container stage to finish, so this should
still be OK).

Additionally, some update on the container side recently enabled
OpenGL in these jobs - but the corresponding code fails to compile.
Thus disable OpenGL here for the time being until someone figured
out the proper fix in the shader code for this.

Mukilan Thiyagarajan b9052d3634 tests/docker: use prebuilt toolchain for debian-hexagon-cross
The current docker image for cross compiling hexagon guests
is manually built since it takes >2 hours to build from source.

This patch:
 1. Solves the above issue by using the prebuilt clang
    toolchain hosted on CodeLinaro [1] and maintained by QUIC [2].
 2. The dockerfile is also switched from multi-stage to single stage
    build to allow the CI docker engine to reuse the layer cache.
 3. Re-enables the hexagon-cross-container job to be always run in
    CI and makes it a non-optional dependency for the
    build-user-hexagon job.

The changes for 1 & 2 together bring down the build time to
~3 minutes in GitLab CI when cache is reused and ~9 minutes
when cache cannot be reused.

Mukilan Thiyagarajan 73acb87be5 configure: Fix check-tcg not executing any tests
After configuring with --target-list=hexagon-linux-user
running `make check-tcg` just prints the following:

```
make: Nothing to be done for 'check-tcg'
```

In the probe_target_compiler function, the 'break'
command is used incorrectly. There are no lexically
enclosing loops associated with that break command which
is an unspecfied behaviour in the POSIX standard.

The dash shell implementation aborts the currently executing
loop, in this case, causing the rest of the logic for the loop
in line 2490 to be skipped, which means no Makefiles are
generated for the tcg target tests.

Fixes: c3b570b5a9 (configure: don't enable
cross compilers unless in target_list)

Define the DEXCR and HDEXCR as special purpose registers.

Each register occupies two SPR indicies, one which can be read in an
unprivileged state and one which can be modified in the appropriate
priviliged state, however both indicies refer to the same underlying
value.

Note that the ISA uses the abbreviation UDEXCR in two different
contexts: the userspace DEXCR, the SPR index which can be read from
userspace (implemented in this patch), and the ultravisor DEXCR, the
equivalent register for the ultravisor state (not implemented).

Philippe Mathieu-Daudé 46d80a56a1 hw/ppc/spapr: Reduce "vof.h" inclusion
Currently objects including "hw/ppc/spapr.h" are forced to be
target specific due to the inclusion of "vof.h" in "spapr.h".

"spapr.h" only uses a Vof pointer, so doesn't require the structure
declaration. The only place where Vof structure is accessed is in
spapr.c, so include "vof.h" there, and forward declare the structure
in "spapr.h".

Philippe Mathieu-Daudé c0a55a0c9d hw/sd/sdhci: Support big endian SD host controller interfaces
Some SDHCI IP can be synthetized in various endianness:
https://github.com/u-boot/u-boot/blob/v2021.04/doc/README.fsl-esdhc

 - CONFIG_SYS_FSL_ESDHC_BE

   ESDHC IP is in big-endian mode. Accessing ESDHC registers can be
   determined by ESDHC IP's endian mode or processor's endian mode.

Our current implementation is little-endian. In order to support
big endianness:

- Rename current MemoryRegionOps as sdhci_mmio_le_ops ('le')
- Add an 'endianness' property to SDHCIState (default little endian)
- Set the 'io_ops' field in realize() after checking the property
- Add the sdhci_mmio_be_ops (big-endian) MemoryRegionOps.

The maintainer is no longer being paid to maintain these components. All
maintainership work is being done in his personal time since the middle
of the 7.2 development cycle.

Change the status of PPC KVM CPUs, PPC TCG CPUs and the pSeries machine
to 'Odd Fixes', reflecting that the maintainer no longer has exclusive
time to dedicate to them. It'll also (hopefully) keep expectations under
check when/if these components are used in a customer product.

Peter Maydell 6394578984 block/io: Check for replay-enabled in bdrv_drain_all_begin()
In commit da0bd74434 we refactored bdrv_drain_all_begin() to pull out
the non-polling part into bdrv_drain_all_begin_nopoll().  This change
broke record-and-replay, because the "return early if replay enabled"
check is now in the sub-function bdrv_drain_all_begin_nopoll(), and
so it only causes us to return from that function, and not from the
calling bdrv_drain_all_begin().

Fix the regression by checking whether replay is enabled in both
functions.

The breakage and fix can be tested via 'make check-avocado': the
tests/avocado/reverse_debugging.py:ReverseDebugging_X86_64.test_x86_64_pc
tests/avocado/reverse_debugging.py:ReverseDebugging_AArch64.test_aarch64_virt
tests were both broken by this.

mformat is needed by grub-mkrescue and hence, add this as one of the
dependencies to run bits tests. This avoids errors such as the following:

Igor Mammedov b1fbf24259 remove DEC 21154 PCI bridge
Code has not been used practically since its inception (2004)
  f2aa58c6f4 UniNorth PCI bridge support
or maybe even earlier, but it was consuming contributors time
as QEMU was being rewritten.
Drop it for now. Whomever would like to actually
use the thing, can make sure it actually works/reintroduce
it back when there is a user.

PS:
I've stumbled upon this when replacing PCIDeviceClass::is_bridge
field with QOM cast to PCI_BRIDGE type. Unused DEC 21154
was the only one trying to use the field with plain PCIDevice.
It's not worth keeping the field around for the sake of the code
that was commented out 'forever'.

Jason Wang 345cc1cbcb vhost: fix vq dirty bitmap syncing when vIOMMU is enabled
When vIOMMU is enabled, the vq->used_phys is actually the IOVA not
GPA. So we need to translate it to GPA before the syncing otherwise we
may hit the following crash since IOVA could be out of the scope of
the GPA log size. This could be noted when using virtio-IOMMU with
vhost using 1G memory.
