2023-10-07util/log: re-allow switching away from stderr log fileFiona Ebner1-0/+2
Commit 59bde21374 ("util/log: do not close and reopen log files when flags are turned off") prevented switching away from stderr on a subsequent invocation of qemu_set_log_internal(). This prevented switching away from stderr with the 'logfile' monitor command as well as an invocation like > ./qemu-system-x86_64 -trace 'qemu_mutex_lock,file=log' from opening the specified log file.

2023-10-07sysemu/kvm: Restrict hvf_get_supported_cpuid() to x86 targetsPhilippe Mathieu-Daudé5-3/+5
hvf_get_supported_cpuid() is only defined for x86 targets (in target/i386/hvf/x86_cpuid.c). Its declaration is pointless on all other targets. All the calls to it in target/i386/cpu.c are guarded by a call on hvf_enabled(), so are elided when HVF is not built in. Therefore we can remove the unnecessary function stub.

2023-10-06linux-user/syscall.c: clean up local variable shadowing in xattr syscallsLaurent Vivier1-4/+4
p is a generic variable in syscall() and can be used by any syscall case, so this patch removes the useless local variable declaration for the following syscalls: TARGET_NR_llistxattr, TARGET_NR_listxattr, TARGET_NR_setxattr, TARGET_NR_lsetxattr, TARGET_NR_getxattr, TARGET_NR_lgetxattr, TARGET_NR_removexattr, TARGET_NR_lremovexattr.

2023-10-06audio/ossaudio: Fix compiler warning with -WshadowThomas Huth1-1/+0
The "err" variable is only used twice in this code, in a very local fashion of first assigning it and then checking it in the next line. So there is no need to declare this variable a second time in the innermost block, we can re-use the variable that is declared at the beginning of the function. This fixes the compiler warning that occurs with "-Wshadow".

2023-10-06mac_via: always clear ADB interrupt when switching to A/UX modeMark Cave-Ayland1-0/+9
When the NetBSD kernel initialises it can leave the ADB interrupt asserted depending upon where in the ADB poll cycle the MacOS ADB interrupt handler is when the NetBSD kernel disables interrupts. The NetBSD ADB driver uses the ADB interrupt state to determine if the ADB is busy and refuses to send ADB commands unless it is clear. To ensure that this doesn't happen, always clear the ADB interrupt when switching to A/UX mode to ensure that the bus enumeration always occurs.

2023-10-06mac_via: work around underflow in TimeDBRA timing loop in SETUPTIMEKMark Cave-Ayland3-0/+119
The MacOS toolbox ROM calculates the number of branches that can be executed per millisecond as part of its timer calibration. Since modern hosts are considerably quicker than original hardware, the negative counter reaches zero before the calibration completes leading to division by zero later in CALCULATESLOD. Instead of trying to fudge the timing loop (which won't work for TimeDBRA/TimeSCCDB anyhow), use the pattern of access to the VIA1 registers to detect when SETUPTIMEK has finished executing and write some well-known good timer values to TimeDBRA and TimeSCCDB taken from real hardware with a suitable scaling factor.

MacOS (un)helpfully leaves the FIFO engine running even when all the samples have been written to the hardware, and expects the FIFO status flags and IRQ to be updated continuously. There is an additional problem in that not all audio backends guarantee an all-zero output when there is no FIFO data available, in particular the Windows dsound backend which re-uses its internal circular buffer causing the last played sound to loop indefinitely. Whilst this is effectively a bug in the Windows dsound backend, work around it for now using a simple heuristic: if the FIFO remains empty for half a cycle (~23ms) then continuously fill the generated buffer with empty silence.
