d327a942aa iotests: Make 110 work with data_file
The only difference is that the json:{} filename of the image looks
different.  We actually do not care about that filename in this test, we
are only interested in (1) that there is a json:{} filename, and (2)
whether the backing filename can be constructed.

So just filter out the json:{} data, thus making this test pass both
with and without data_file.

990f9bcc73 iotests: Make 091 work with data_file
The image end offset as reported by qemu-img check is different when
using an external data file; we do not care about its value here, so we
can just filter it.  Incidentally, common.rc already has _check_test_img
for us which does exactly that.

f91ecbd74e iotests: Use _rm_test_img for deleting test images
Just rm will not delete external data files.  Use _rm_test_img every
time we delete a test image.

(In the process, clean up the indentation of every _cleanup() this patch
touches.)

((Also, use quotes consistently.  I am happy to see unquoted instances
like "rm -rf $TEST_DIR/..." go.))

407fb56a8e iotests: Replace IMGOPTS= by -o
Tests should not overwrite all user-supplied image options, but only add
to it (which will effectively overwrite conflicting values).  Accomplish
this by passing options to _make_test_img via -o instead of $IMGOPTS.

For some tests, there is no functional change because they already only
appended options to IMGOPTS.  For these, this patch is just a
simplification.

For others, this is a change, so they now heed user-specified $IMGOPTS.
Some of those tests do not work with all image options, though, so we
need to disable them accordingly.

8b6d7be6a6 iotests: Add -o and --no-opts to _make_test_img
Blindly overriding IMGOPTS is suboptimal as this discards user-specified
options.  Whatever options the test needs should simply be appended.

Some tests do this (with IMGOPTS=$(_optstr_add "$IMGOPTS" "...")), but
that is cumbersome.  It’s simpler to just give _make_test_img an -o
parameter with which tests can add options.

Some tests actually must override the user-specified options, though,
for example when creating an image in a different format than the test
$IMGFMT.  For such cases, --no-opts allows clearing the current option
list.

b043b07ce3 iotests: Replace IMGOPTS by _unsupported_imgopts
Some tests require compat=1.1 and thus set IMGOPTS='compat=1.1'
globally.  That is not how it should be done; instead, they should
simply set _unsupported_imgopts to compat=0.10 (compat=1.1 is the
default anyway).

This makes the tests heed user-specified $IMGOPTS.  Some do not work
with all image options, though, so we need to disable them accordingly.

7ab2a25890 iotests: Filter refcount_order in 036
This test can run just fine with other values for refcount_bits, so we
should filter the value from qcow2.py's dump-header.  In fact, we can
filter everything but the feature bits and header extensions, because
that is what the test is about.

(036 currently ignores user-specified image options, but that will be
fixed in the next patch.)

a1db8733d2 qcow2-bitmaps: fix qcow2_can_store_new_dirty_bitmap
qcow2_can_store_new_dirty_bitmap works wrong, as it considers only
bitmaps already stored in the qcow2 image and ignores persistent
BdrvDirtyBitmap objects.

So, let's instead count persistent BdrvDirtyBitmaps. We load all qcow2
bitmaps on open, so there should not be any bitmap in the image for
which we don't have BdrvDirtyBitmaps version. If it is - it's a kind of
corruption, and no reason to check for corruptions here (open() and
close() are better places for it).

69c6449ff1 blkdebug: Allow taking/unsharing permissions
Sometimes it is useful to be able to add a node to the block graph that
takes or unshare a certain set of permissions for debugging purposes.
This patch adds this capability to blkdebug.

(Note that you cannot make blkdebug release or share permissions that it
needs to take or cannot share, because this might result in assertion
failures in the block layer.  But if the blkdebug node has no parents,
it will not take any permissions and share everything by default, so you
can then freely choose what permissions to take and share.)

7b1d9c4df0 block: Add bdrv_qapi_perm_to_blk_perm()
We need some way to correlate QAPI BlockPermission values with
BLK_PERM_* flags.  We could:

(1) have the same order in the QAPI definition as the the BLK_PERM_*
    flags are in LSb-first order.  However, then there is no guarantee
    that they actually match (e.g. when someone modifies the QAPI schema
    without thinking of the BLK_PERM_* definitions).
    We could add static assertions, but these would break what’s good
    about this solution, namely its simplicity.

(2) define the BLK_PERM_* flags based on the BlockPermission values.
    But this way whenever someone were to modify the QAPI order
    (perfectly sensible in theory), the BLK_PERM_* values would change.
    Because these values are used for file locking, this might break
    file locking between different qemu versions.

Therefore, go the slightly more cumbersome way: Add a function to
translate from the QAPI constants to the BLK_PERM_* flags.

c8fa6079eb arm/arm-powerctl: rebuild hflags after setting CP15 bits in arm_set_cpu_on()
After setting CP15 bits in arm_set_cpu_on() the cached hflags must
be rebuild to reflect the changed processor state. Without rebuilding,
the cached hflags would be inconsistent until the next call to
arm_rebuild_hflags(). When QEMU is compiled with debugging enabled
(--enable-debug), this problem is captured shortly after the first
call to arm_set_cpu_on() for CPUs running in ARM 32-bit non-secure mode:

  qemu-system-arm: target/arm/helper.c:11359: cpu_get_tb_cpu_state:
  Assertion `flags == rebuild_hflags_internal(env)' failed.

b255cafb59 hw/arm/smmuv3: Report F_STE_FETCH fault address in correct word position
The smmuv3_record_event() function that generates the F_STE_FETCH error
uses the EVT_SET_ADDR macro to record the fetch address, placing it in
32-bit words 4 and 5.

The correct position for this address is in words 6 and 7, per the
SMMUv3 Architecture Specification.

Update the function to use the EVT_SET_ADDR2 macro instead, which is the
macro intended for writing to these words.

a7f65ceb85 hw/arm/smmuv3: Use correct bit positions in EVT_SET_ADDR2 macro
The bit offsets in the EVT_SET_ADDR2 macro do not match those specified
in the ARM SMMUv3 Architecture Specification. In all events that use
this macro, e.g. F_WALK_EABT, the faulting fetch address or IPA actually
occupies the 32-bit words 6 and 7 in the event record contiguously, with
the upper and lower unused bits clear due to alignment or maximum
supported address bits. How many bits are clear depends on the
individual event type.

Update the macro to write to the correct words in the event record so
that guest drivers can obtain accurate address information on events.

05ff2fb80c hw/arm/smmuv3: Check stream IDs against actual table LOG2SIZE
When checking whether a stream ID is in range of the stream table, we
have so far been only checking it against our implementation limit
(SMMU_IDR1_SIDSIZE). However, the guest can program the
STRTAB_BASE_CFG.LOG2SIZE field to a size that is smaller than this
limit.

Check the stream ID against this limit as well to match the hardware
behavior of raising C_BAD_STREAMID events in case the limit is exceeded.
Also, ensure that we do not go one entry beyond the end of the table by
checking that its index is strictly smaller than the table size.

3293b9f514 hw/arm/smmuv3: Correct SMMU_BASE_ADDR_MASK value
There are two issues with the current value of SMMU_BASE_ADDR_MASK:

- At the lower end, we are clearing bits [4:0]. Per the SMMUv3 spec,
  we should also be treating bit 5 as zero in the base address.
- At the upper end, we are clearing bits [63:48]. Per the SMMUv3 spec,
  only bits [63:52] must be explicitly treated as zero.

Update the SMMU_BASE_ADDR_MASK value to mask out bits [63:52] and [5:0].

3d44c60500 hw/arm/smmuv3: Apply address mask to linear strtab base address
In the SMMU_STRTAB_BASE register, the stream table base address only
occupies bits [51:6]. Other bits, such as RA (bit [62]), must be masked
out to obtain the base address.

The branch for 2-level stream tables correctly applies this mask by way
of SMMU_BASE_ADDR_MASK, but the one for linear stream tables does not.

Apply the missing mask in that case as well so that the correct stream
base address is used by guests which configure a linear stream table.

Linux guests are unaffected by this change because they choose a 2-level
stream table layout for the QEMU SMMUv3, based on the size of its stream
ID space.

96eec6b2b3 target/arm: Prepare generic timer for per-platform CNTFRQ
The ASPEED AST2600 clocks the generic timer at the rate of HPLL. On
recent firmwares this is at 1125MHz, which is considerably quicker than
the assumed 62.5MHz of the current generic timer implementation. The
delta between the value as read from CNTFRQ and the true rate of the
underlying QEMUTimer leads to sticky behaviour in AST2600 guests.

Add a feature-gated property exposing CNTFRQ for ARM CPUs providing the
generic timer. This allows platforms to configure CNTFRQ (and the
associated QEMUTimer) to the appropriate frequency prior to starting the
guest.

As the platform can now determine the rate of CNTFRQ we're exposed to
limitations of QEMUTimer that didn't previously materialise: In the
course of emulation we need to arbitrarily and accurately convert
between guest ticks and time, but we're constrained by QEMUTimer's use
of an integer scaling factor. The effect is QEMUTimer cannot exactly
capture the period of frequencies that do not cleanly divide
NANOSECONDS_PER_SECOND for scaling ticks to time. As such, provide an
equally inaccurate scaling factor for scaling time to ticks so at least
a self-consistent inverse relationship holds.

7def875482 target/arm: Abstract the generic timer frequency
Prepare for SoCs such as the ASPEED AST2600 whose firmware configures
CNTFRQ to values significantly larger than the static 62.5MHz value
currently derived from GTIMER_SCALE. As the OS potentially derives its
timer periods from the CNTFRQ value the lack of support for running
QEMUTimers at the appropriate rate leads to sticky behaviour in the
guest.

Substitute the GTIMER_SCALE constant with use of a helper to derive the
period from gt_cntfrq_hz stored in struct ARMCPU. Initially set
gt_cntfrq_hz to the frequency associated with GTIMER_SCALE so current
behaviour is maintained.

4a0245b625 target/arm: Remove redundant scaling of nexttick
The corner-case codepath was adjusting nexttick such that overflow
wouldn't occur when timer_mod() scaled the value back up. Remove a use
of GTIMER_SCALE and avoid unnecessary operations by calling
timer_mod_ns() directly.
