2024-04-02vga: adjust dirty memory region if pel panning is activePaolo Bonzini
When pel panning is active, one more byte is read from each of the VGA memory planes. This has to be accounted in the computation of region_end, otherwise vga_draw_graphic() fails an assertion: qemu-system-i386: ../system/physmem.c:946: cpu_physical_memory_snapshot_get_dirty: Assertion `start + length <= snap->end' failed. Reported-by: Helge Konetzka <hk@zapateado.de> Resolves: https://gitlab.com/qemu-project/qemu/-/issues/2244 Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2024-04-02vga: move computation of dirty memory region laterPaolo Bonzini
Move the computation of region_start and region_end after the value of "bits" is known. This makes it possible to distinguish modes that support horizontal pel panning from modes that do not. Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2024-04-02vga: merge conditionals on shift control registerPaolo Bonzini
There are two sets of conditionals using the shift control bits: one to verify the palette and adjust disp_width, one to compute the "v" and "bits" variables. Merge them into one, with the extra benefit that we now have the "bits" value available early and can use it to compute region_end.

Coverity complains that the check introduced in commit 3f934817 suggests that qiov could be NULL and we dereference it before reaching the check. In fact, all of the callers pass a non-NULL pointer, so just remove the misleading check.

Similarly to commit 9de9fa5cf2 ("hw/arm/smmu-common: Avoid using inlined functions with external linkage"): None of our code base require / use inlined functions with external linkage.

2024-04-02raspi4b: Reduce RAM to 1Gb on 32-bit hostsCédric Le Goater
Change the board revision number and RAM size to 1Gb on 32-bit hosts. On these systems, RAM has a 2047 MB limit and this breaks the tests.

2024-04-02tests/qtest: Fix STM32L4x5 GPIO test on 32-bitCédric Le Goater
The test mangles the GPIO address and the pin number in the qtest_add_data_func data parameter. Doing so, it assumes that the host pointer size is always 64-bit, which breaks on 32-bit : ../tests/qtest/stm32l4x5_gpio-test.c: In function ‘test_gpio_output_mode’: ../tests/qtest/stm32l4x5_gpio-test.c:272:25: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast] 272 | unsigned int pin = ((uint64_t)data) & 0xF; | ^ ../tests/qtest/stm32l4x5_gpio-test.c:273:22: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast] 273 | uint32_t gpio = ((uint64_t)data) >> 32; | ^ To fix, improve the mangling of the GPIO address and pin number fields by using GPIO_SIZE so that the resulting value fits in a 32-bit pointer. While at it, include some helpers to hide the details.

If the group of the highest priority pending interrupt is disabled via ICC_IGRPEN*, the ICC_HPPIR* registers should return INTID_SPURIOUS, not the interrupt ID. (See the GIC architecture specification pseudocode functions ICC_HPPIR1_EL1[] and HighestPriorityPendingInterrupt().)

2024-04-02target/arm: take HSTR traps of cp15 accesses to EL2, not EL1Peter Maydell
The HSTR_EL2 register allows the hypervisor to trap AArch32 EL1 and EL0 accesses to cp15 registers. We incorrectly implemented this so they trap to EL1 when we detect the need for a HSTR trap at code generation time. (The check in access_check_cp_reg() which we do at runtime to catch traps from EL0 is correctly routing them to EL2.) Use the correct target EL when generating the code to take the trap.

2024-04-01usb-audio: Fix invalid values in AudioControl descriptorsJoonas Kankaala
This fixes the invalid bInterfaceProtocol value 0x04 in the USB audio AudioControl descriptors. It should be zero. While Linux and Windows forgive this error, macOS 14 Sonoma does not. The usb-audio device does not appear in macOS sound settings even though the device is recognized and shows up in USB system information. According to the USB audio class specs 1.0-4.0, valid values are 0x00, 0x20, 0x30 and 0x40. (Note also that Linux prints the warning "unknown interface protocol 0x4, assuming v1", but then proceeds as if the value was zero.) This also fixes the invalid wTotalLength value in the multi-channel setup AudioControl interface header descriptor (used when multi=on and out.mixing-engine off). The combined length of all the descriptors there add up to 0x37, not 0x38. In Linux, "lsusb -D ..." displays incomplete descriptor information when this length is incorrect.

2024-03-31migration: Set migration error in migration_completion()Avihai Horon
After commit 9425ef3f990a ("migration: Use migrate_has_error() in close_return_path_on_source()"), close_return_path_on_source() assumes that migration error is set if an error occurs during migration. This may not be true if migration errors in migration_completion(). For example, if qemu_savevm_state_complete_precopy() errors, migration error will not be set. This in turn, will cause a migration hang bug, similar to the bug that was fixed by commit 22b04245f0d5 ("migration: Join the return path thread before releasing to_dst_file"), as shutdown() will not be issued for the return-path channel.

2024-03-30target/ppc: Do not clear MSR[ME] on MCE interrupts to supervisorNicholas Piggin
Hardware clears the MSR[ME] bit when delivering a machine check interrupt, so that is what QEMU does. The spapr environment runs in supervisor mode though, and receives machine check interrupts after they are processed by the hypervisor, and MSR[ME] must always be enabled in supervisor mode (otherwise it could checkstop the system). So MSR[ME] must not be cleared when delivering machine checks to the supervisor. The fix to prevent supervisor mode from modifying MSR[ME] also prevented it from re-enabling the incorrectly cleared MSR[ME] bit when returning from handling the interrupt. Before that fix, the problem was not very noticable with well-behaved code. So the Fixes tag is not strictly correct, but practically they go together. Found by kvm-unit-tests machine check tests (not yet upstream).

2024-03-30target/ppc: Fix GDB register indexing on secondary CPUsBenjamin Gray
The GDB server protocol assigns an arbitrary numbering of the SPRs. We track this correspondence on each SPR with gdb_id, using it to resolve any SPR requests GDB makes. Early on we generate an XML representation of the SPRs to give GDB, including this numbering. However the XML is cached globally, and we skip setting the SPR gdb_id values on subsequent threads if we detect it is cached. This causes QEMU to fail to resolve SPR requests against secondary CPUs because it cannot find the matching gdb_id value on that thread's SPRs. This is a minimal fix to first assign the gdb_id values, then return early if the XML is cached. Otherwise we generate the XML using the now already initialised gdb_id values.

2024-03-30target/ppc: Restore [H]DEXCR to 64-bitsBenjamin Gray
The DEXCR emulation was recently changed to a 32-bit register, possibly because it does have a 32-bit read-only view. It is a full 64-bit SPR though, so use the corresponding 64-bit write functions.
