2022-10-31contrib/plugins: protect execlog's last_exec expansionAlex Bennée
We originally naively treated expansion as safe because we expected each new CPU/thread to appear in order. However the -M raspi2 model triggered a case where a new high cpu_index thread started executing just before a smaller one. Clean this up by converting the GArray into the simpler GPtrArray and then holding a lock for the expansion.

2022-10-31contrib/plugins: enable debug on CONFIG_DEBUG_TCGAlex Bennée
We used to rely on QEMU_CFLAGS to expose the debug flags but now this is synthesised by meson and only available to the main build. Add our own flags if we detect the build has been enabled with CONFIG_DEBUG_TCG (which is the default for --enable-debug anyway).

2022-05-16vhost-user-scsi: avoid unlink(NULL) with fd passingStefan Hajnoczi
Commit 747421e949fc1eb3ba66b5fcccdb7ba051918241 ("Implements Backend Program conventions for vhost-user-scsi") introduced fd-passing support as part of implementing the vhost-user backend program conventions. When fd passing is used the UNIX domain socket path is NULL and we must not call unlink(2). The unlink(2) call is necessary when the listen socket, lsock, was created successfully since that means the UNIX domain socket is visible in the file system.

2022-05-03util: rename qemu_*block() socket functionsMarc-André Lureau
The qemu_*block() functions are meant to be be used with sockets (the win32 implementation expects SOCKET) Over time, those functions where used with Win32 SOCKET or file-descriptors interchangeably. But for portability, they must only be used with socket-like file-descriptors. FDs can use g_unix_set_fd_nonblocking() instead. Rename the functions with "socket" in the name to prevent bad usages. This is effectively reverting commit f9e8cacc5557e43 ("oslib-posix: rename socket_set_nonblock() to qemu_set_nonblock()").

This adds an implementation of a simple L2 configuration, in which a unified L2 cache (stores both blocks of instructions and data) is maintained for each core separately, with no inter-core interaction taken in account. The L2 cache is used as a backup for L1 and is only accessed if the wanted block does not exist in L1. In terms of multi-threaded user-space emulation, the same approximation of L1 is done, a static number of caches is maintained, and each and every memory access initiated by a thread will have to go through one of the available caches. An atomic increment is used to maintain the number of L2 misses per instruction.

2021-09-02plugins/hotpages: introduce sortby arg and parsed bool args correctlyMahmoud Mandour
Since plugin arguments now expect boolean arguments, a plugin argument name "sortby" now expects a value of "read", "write", or "address". "io" arg is now expected to be passed as a full-form boolean parameter, i.e. "io=on|true|yes|off|false|no" Signed-off-by: Mahmoud Mandour <ma.mandourr@gmail.com> Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Message-Id: <20210730135817.17816-4-ma.mandourr@gmail.com>
2021-09-02plugins/cache: supported multicore cache modellingMahmoud Mandour
Multicore L1 cache modelling is introduced and is supported for both full system emulation and linux-user. For full-system emulation, L1 icache and dcache are maintained for each available core, since this information is exposed to the plugin through `qemu_plugin_n_vcpus()`. For linux-user, a static number of cores is assumed (default 1 core, and can be provided as a plugin argument `cores=N`). Every memory access goes through one of these caches, this approach is taken as it's somewhat akin to what happens on real setup, where a program that dispatches more threads than the available cores, they'll thrash each other Signed-off-by: Mahmoud Mandour <ma.mandourr@gmail.com> Message-Id: <20210803151301.123581-2-ma.mandourr@gmail.com> Signed-off-by: Alex Bennée <alex.bennee@linaro.org>

This manifests itself when associativity degree is greater than the number of sets and FIFO is used, otherwise it's also a memory leak whenever FIFO was used.
