 called without KVM. Those functions should be guarded by kvm_enabled(),
 but should also be robust to refactoring mistakes. Putting a
 g_assert_not_reached() in the function should help. Additionally,
 the g_assert_not_reached() calls may actually help the linker remove
 some code.
 We remove the stubs for kvm_arm_get/put_virtual_time(), as they aren't
 necessary at all - the only caller is in kvm.c

+[PULL 12/30] tests/avocado: retire the Aarch64 TCG tests from boot_linux.py
+From: Alex Bennée <alex.bennee@linaro.org>
 The two TCG tests for GICv2 and GICv3 are very heavy weight distros
 that take a long time to boot up, especially for an --enable-debug
 build. The total code coverage they give is:
   Overall coverage rate:
     lines......: 11.2% (59584 of 530123 lines)
     functions..: 15.0% (7436 of 49443 functions)
     branches...: 6.3% (19273 of 303933 branches)
 We already get pretty close to that with the machine_aarch64_virt
 tests which only does one full boot (~120s vs ~600s) of alpine. We
 expand the kernel+initrd boot (~8s) to test both GICs and also add an
 RNG device and a block device to generate a few IRQs and exercise the
 storage layer. With that we get to a coverage of:
   Overall coverage rate:
     lines......: 11.0% (58121 of 530123 lines)
     functions..: 14.9% (7343 of 49443 functions)
     branches...: 6.0% (18269 of 303933 branches)
 which I feel is close enough given the massive time saving. If we want
 to target any more sub-systems we can use lighter weight more directed
 tests.

-New patch
+[PULL 13/30] hw/arm/smmuv3: Add GBPA register
+From: Mostafa Saleh <smostafa@google.com>
+GBPA register can be used to globally abort all
+transactions.
+It is described in the SMMU manual in "6.3.14 SMMU_GBPA".
+ABORT reset value is IMPLEMENTATION DEFINED, it is chosen to
+be zero(Do not abort incoming transactions).
+Other fields have default values of Use Incoming.
+If UPDATE is not set, the write is ignored. This is the only permitted
+behavior in SMMUv3.2 and later.(6.3.14.1 Update procedure)
+As this patch adds a new state to the SMMU (GBPA), it is added
+in a new subsection for forward migration compatibility.
+GBPA is only migrated if its value is different from the reset value.
+It does this to be backward migration compatible if SW didn't write
+the register.

-[PULL 09/12] hw/arm/virt: Move kvm pmu setup to virt_cpu_post_init
+[PULL 15/30] arm/virt: don't try to spell out the accelerator
-From: Andrew Jones <drjones@redhat.com>
+From: Cornelia Huck <cohuck@redhat.com>
-Move the KVM PMU setup part of fdt_add_pmu_nodes() to
+Just use current_accel_name() directly.
 virt_cpu_post_init(), which is a more appropriate location. Now
 fdt_add_pmu_nodes() is also named more appropriately, because it
 no longer does anything but fdt node creation.
-No functional change intended.

-New patch
+[PULL 25/30] target/arm: Move cpregs code out of cpu.h
+From: Fabiano Rosas <farosas@suse.de>
 Since commit cf7c6d1004 ("target/arm: Split out cpregs.h") we now have
 a cpregs.h header which is more suitable for this code.
 Code moved verbatim.

Fix integer handling issues handling issue reported by Coverity:

hw/ssi/npcm7xx_fiu.c: 162 in npcm7xx_fiu_flash_read()
  >>>     CID 1432730:  Integer handling issues  (NEGATIVE_RETURNS)
  >>>     "npcm7xx_fiu_cs_index(fiu, f)" is passed to a parameter that cannot be negative.
  162         npcm7xx_fiu_select(fiu, npcm7xx_fiu_cs_index(fiu, f));

hw/ssi/npcm7xx_fiu.c: 221 in npcm7xx_fiu_flash_write()
  218         cs_id = npcm7xx_fiu_cs_index(fiu, f);
  219         trace_npcm7xx_fiu_flash_write(DEVICE(fiu)->canonical_path, cs_id, addr,
  220                                       size, v);
  >>>     CID 1432729:  Integer handling issues  (NEGATIVE_RETURNS)
  >>>     "cs_id" is passed to a parameter that cannot be negative.
  221         npcm7xx_fiu_select(fiu, cs_id);

Since the index of the flash can not be negative, return an
unsigned type.

SMMUv3 has an error in a previous patch where an i was transposed to a 1
meaning interrupts would not have been correctly assigned to the SMMUv3
instance.

Original commit did not allocate IRQs for the SMMUv3 in the irqmap
effectively using irq 0->3 (shared with other devices). Assuming
original intent was to allocate unique IRQs then add an allocation
to the irqmap.

2.20.1

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

The "BCM2835 ARM Peripherals" datasheet [*] chapter 2
("Auxiliaries: UART1 & SPI1, SPI2"), list the register
sizes as 3/8/16/32 bits. We assume this means this
peripheral allows 8-bit accesses.

This was not an issue until commit 5d971f9e67 which reverted
("memory: accept mismatching sizes in memory_region_access_valid").

The model is implemented as 32-bit accesses (see commit 97398d900c,
all registers are 32-bit) so replace MemoryRegionOps.valid as
MemoryRegionOps.impl, and re-introduce MemoryRegionOps.valid
with a 8/32-bit range.

[*] https://www.raspberrypi.org/app/uploads/2012/02/BCM2835-ARM-Peripherals.pdf

2.20.1

From: Andrew Jones <drjones@redhat.com>

When we compile without KVM support !defined(CONFIG_KVM) we generate
stubs for functions that the linker will still encounter. Sometimes
these stubs can be executed safely and are placed in paths where they
get executed with or without KVM. Other functions should never be
called without KVM. Those functions should be guarded by kvm_enabled(),
but should also be robust to refactoring mistakes. Putting a
g_assert_not_reached() in the function should help. Additionally,
the g_assert_not_reached() calls may actually help the linker remove
some code.

We remove the stubs for kvm_arm_get/put_virtual_time(), as they aren't
necessary at all - the only caller is in kvm.c

We'll add more to this new function in coming patches so we also
state the gic must be created and call it below create_gic().

From: Andrew Jones <drjones@redhat.com>

Move the KVM PMU setup part of fdt_add_pmu_nodes() to
virt_cpu_post_init(), which is a more appropriate location. Now
fdt_add_pmu_nodes() is also named more appropriately, because it
no longer does anything but fdt node creation.

No functional change intended.

We add the kvm-steal-time CPU property and implement it for machvirt.
A tiny bit of refactoring was also done to allow pmu and pvtime to
use the same vcpu device helper functions.

QEMU supports a 48-bit physical address range, but we don't currently
expose it in the '-cpu max' ID registers (you get the same range as
Cortex-A57, which is 44 bits).

Set the ID_AA64MMFR0.PARange field to indicate 48 bits.

      target/arm: Declare CPU <-> NVIC helpers in 'hw/intc/armv7m_nvic.h'
      hw/arm: Add missing XLNX_ZYNQMP_ARM -> USB_DWC3 Kconfig dependency

From: Philippe Mathieu-Daudé <philmd@linaro.org>

Manually convert to OBJECT_DECLARE_SIMPLE_TYPE() macro,
similarly to automatic conversion from commit 8063396bf3
("Use OBJECT_DECLARE_SIMPLE_TYPE when possible").

arm_v7m_mmu_idx_all() and arm_v7m_mmu_idx_for_secstate_and_priv()
are only used for system emulation in m_helper.c.
Move the definitions to avoid prototype forward declarations.

Although the 'eabi' field is only used in user emulation where
CPU reset doesn't occur, it doesn't belong to the area to reset.
Move it after the 'end_reset_fields' for consistency.

There is no point in using a void pointer to access the NVIC.
Use the real type to avoid casting it while debugging.

2.34.1

From: Alex Bennée <alex.bennee@linaro.org>

The two TCG tests for GICv2 and GICv3 are very heavy weight distros
that take a long time to boot up, especially for an --enable-debug
build. The total code coverage they give is:

Overall coverage rate:
    lines......: 11.2% (59584 of 530123 lines)
    functions..: 15.0% (7436 of 49443 functions)
    branches...: 6.3% (19273 of 303933 branches)

We already get pretty close to that with the machine_aarch64_virt
tests which only does one full boot (~120s vs ~600s) of alpine. We
expand the kernel+initrd boot (~8s) to test both GICs and also add an
RNG device and a block device to generate a few IRQs and exercise the
storage layer. With that we get to a coverage of:

Overall coverage rate:
    lines......: 11.0% (58121 of 530123 lines)
    functions..: 14.9% (7343 of 49443 functions)
    branches...: 6.0% (18269 of 303933 branches)

which I feel is close enough given the massive time saving. If we want
to target any more sub-systems we can use lighter weight more directed
tests.

2.34.1

From: Mostafa Saleh <smostafa@google.com>

GBPA register can be used to globally abort all
transactions.

It is described in the SMMU manual in "6.3.14 SMMU_GBPA".
ABORT reset value is IMPLEMENTATION DEFINED, it is chosen to
be zero(Do not abort incoming transactions).

Other fields have default values of Use Incoming.

If UPDATE is not set, the write is ignored. This is the only permitted
behavior in SMMUv3.2 and later.(6.3.14.1 Update procedure)

As this patch adds a new state to the SMMU (GBPA), it is added
in a new subsection for forward migration compatibility.
GBPA is only migrated if its value is different from the reset value.
It does this to be backward migration compatible if SW didn't write
the register.

for "all" builds (tcg + kvm), we want to avoid doing
the psci check if tcg is built-in, but not enabled.

Move this earlier to make the next patch diff cleaner. While here
update the comment slightly to not give the impression that the
misalignment affects only TCG.

Since commit cf7c6d1004 ("target/arm: Split out cpregs.h") we now have
a cpregs.h header which is more suitable for this code.

Code moved verbatim.

If a test was tagged with the "accel" tag and the specified
accelerator it not present in the qemu binary, cancel the test.

We can now write tests without explicit calls to require_accelerator,
just the tag is enough.

Now that the cortex-a15 is under CONFIG_TCG, use as default CPU for a
KVM-only build the 'max' cpu.

Note that we cannot use 'host' here because the qtests can run without
any other accelerator (than qtest) and 'host' depends on KVM being
enabled.
