hw/xtensa: fix reset value of MIROUT register of MX PIC

2022-05-06T22:27:40+00:00

MX PIC comes out of reset with IRQ routing registers set to 0, thus not delivering any external IRQ to any connected CPU by default. Fix the model to match the hardware. Signed-off-by: Max Filippov

Replace TARGET_WORDS_BIGENDIAN

2022-04-06T08:50:37+00:00

Convert the TARGET_WORDS_BIGENDIAN macro, similarly to what was done with HOST_BIG_ENDIAN. The new TARGET_BIG_ENDIAN macro is either 0 or 1, and thus should always be defined to prevent misuse.

Use g_new() & friends where that makes obvious sense

2022-03-21T14:44:44+00:00

g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer, for two reasons. One, it catches multiplication overflowing size_t. Two, it returns T * rather than void *, which lets the compiler catch more type errors. This commit only touches allocations with size arguments of the form sizeof(T). Patch created mechanically with: $ spatch --in-place --sp-file scripts/coccinelle/use-g_new-etc.cocci \ --macro-file scripts/cocci-macro-file.h FILES...

vl: make qemu_get_machine_opts static

load_elf: Remove unused address variables from callers

2020-09-25T23:52:08+00:00

Several callers of load_elf() pass pointers for lowaddr and highaddr parameters which are then not used for anything. This may stem from a misunderstanding that load_elf need a value here but in fact it can take NULL to ignore these values. Remove such unused variables and pass NULL instead from callers that don't need these.

qemu/atomic.h: rename atomic_ to qatomic_

2020-09-23T15:07:44+00:00

clang's C11 atomic_fetch_*() functions only take a C11 atomic type pointer argument. QEMU uses direct types (int, etc) and this causes a compiler error when a QEMU code calls these functions in a source file that also included via a system header file: $ CC=clang CXX=clang++ ./configure ... && make ../util/async.c:79:17: error: address argument to atomic operation must be a pointer to _Atomic type ('unsigned int *' invalid) Avoid using atomic_*() names in QEMU's atomic.h since that namespace is used by . Prefix QEMU's APIs with 'q' so that atomic.h and can co-exist. I checked /usr/include on my machine and searched GitHub for existing "qatomic_" users but there seem to be none. This patch was generated using: $ git grep -h -o '\/tmp/changed_identifiers $ for identifier in $(%q$identifier%g" \ $(git grep -I -l "\<$identifier\>") done I manually fixed line-wrap issues and misaligned rST tables.

target/xtensa: implement NMI support

2020-08-21T19:48:14+00:00

When NMI is configured it is taken regardless of INTENABLE SR contents, PS.INTLEVEL or PS.EXCM. It is cleared automatically once it's taken. Add nmi_level to XtensaConfig, puth there NMI level from the overlay or XCHAL_NUM_INTLEVELS + 1 when NMI is not configured. Add NMI mask to INTENABLE SR and limit CINTLEVEL to nmi_level - 1 when determining pending IRQ level in check_interrupt(). Always take and clear pending interrupt at nmi_level in the handle_interrupt(). Signed-off-by: Max Filippov
