It was unclear what was the supported public interface. I.e. when refactoring the code, what functions/classes are important to retain.

The arguments extracted from `sys.argv` named and unpacked to make it clear what the arguments are and what they're used for. The two input files were opened, but never explicitly closed. File usage changed to use `with` statement to take care of this. At the same time, ownership of the file-object is moved up to `run` function. Added option to process to support file-like objects.

The call to `getargspec` was deprecated and in Python 3.11 it has been removed in favor of `getfullargspec`. `getfullargspec` is compatible with QEMU's requirement of at least Python version 3.6.

A failed call to `read_header` wouldn't be handled the same for the two different code paths (one path would try to use `None` as a list). Changed to raise exception to be handled centrally.

Instead of explicitly calling `begin` and `end`, we can change the class to use the context-manager paradigm. This is mostly a styling choice, used in modern Python code. But it also allows for more advanced analyzers to handle exceptions gracefully in the `__exit__` method (not demonstrated here).

Moved event_mapping and event_id_to_name down one level in the function call-stack to keep variable instantiation and usage closer (`process` and `run` has no use of the variables; `read_trace_records` does). Instead of passing event_mapping and event_id_to_name to the bottom of the call-stack, we move their use to `read_trace_records`. This separates responsibility and ownership of the information. `read_record` now just reads the arguments from the file-object by knowning the total number of bytes. Parsing it to specific arguments is moved up to `read_trace_records`. Special handling of dropped events removed, as they can be handled by the general code.

To avoid duplicate code depending on input types and to better handle open/close of log with a context-manager, we move the logic of process into _process.

Moved event processing to the Analyzer class to separate specific analyzer logic (like caching and function signatures) from the _process function. This allows for new types of Analyzer-based subclasses without changing the core code. Note, that the fn_cache is important for performance in cases where the analyzer is branching away from the catch-all a lot. The cache has no measurable performance penalty.

By moving the dynamic argument construction to keyword-arguments, we can remove all of the specialized handling, and streamline it. If a tracing method wants to access these, they can define the kwargs, or ignore it be placing `**kwargs` at the end of the function's arguments list.

Currently, a few code paths exist in the function vmstate_save_state_v, which ultimately leads to a migration failure. However, an update in the current MigrationState for the error description is never done. vmstate.c somehow doesn't seem to allow the use of migrate_set_error due to some dependencies for unit tests.

The migration qtest all the way up to this point used to work by sheer luck relying on the contents of all pages from 1MiB to 100MiB to contain the same one value in the first byte initially. This easily breaks if we reduce the amount of RAM for the test instances from 150MiB to e.g 110MiB since that makes SeaBIOS dirty some of the pages starting at about 0x5dd2000 (~93 MiB) as it reuses those for the HighMemory allocator since commit dc88f9b72df ("malloc: use large ZoneHigh when there is enough memory").

Extend the migration URI to support file:<filename>. This can be used for any migration scenario that does not require a reverse path. It can be used as an alternative to 'exec:cat > file' in minimized containers that do not contain /bin/sh, and it is easier to use than the fd:<fdname> URI. It can be used in HMP commands, and as a qemu command-line parameter. For best performance, guest ram should be shared and x-ignore-shared should be true, so guest pages are not written to the file, in which case the guest may remain running. If ram is not so configured, then the user is advised to stop the guest first. Otherwise, a busy guest may re-dirty the same page, causing it to be appended to the file multiple times, and the file may grow unboundedly.

When doing so, add documentations and reformat the code to make it much easier to read.

Currently we set _FORTIFY_SOURCE=2 as a compiler argument when the meson 'optimization' setting is non-zero, the compiler is GCC and the target is Linux. While the default QEMU optimization level is 2, user could override this by setting CFLAGS="-O0" or --extra-cflags="-O0" when running configure and this won't be reflected in the meson 'optimization' setting. As a result we try to enable _FORTIFY_SOURCE=2 and then the user gets compile errors as it only works with optimization. Rather than trying to improve detection in meson, it is simpler to just check the __OPTIMIZE__ define from osdep.h. The comment about being incompatible with clang appears to be outdated, as compilation works fine without excluding clang. In the coroutine code we must set _FORTIFY_SOURCE=0 to stop the logic in osdep.h then enabling it. Signed-off-by: Daniel P.

into staging bsd-user mmap and exec branches from gsoc This pull request represents the mmap and exec changes from Karim Taha for his GSoC project. They represent all the mmap and exec related system calls and get bsd-user to the point that a dynamic hello-world works (at least for armv7). There are a couple of patch check errors, but they are the lessor evil: I made purposely bad style choices to ensure all the commits compiled (and i undid the style choices in subsequent commits). I pushed an earlier version to gitlab, and all but the riscv64 pipelines were green. Since bsd-user doesn't change anything related to ricsv64 (there's no support in qemu-project repo, though we do have it in the bsd-user fork: coming soon). I think this is good to go. https://gitlab.com/bsdimp/qemu.git Warner # -----BEGIN PGP SIGNATURE----- # Comment: GPGTools - https://gpgtools.org # # iQIzBAABCgAdFiEEIDX4lLAKo898zeG3bBzRKH2wEQAFAmUcpC4ACgkQbBzRKH2w # EQDD9xAA3Rg0AnfnFrd+AoWRb/1/gOuO0v+dEGXj50qnGY8OmHeYtg3XecYPArBq # EicZzL/OG7UZKMl5OfrmGP9tbr32yfeRUTe3AGGHfmnSb11q0yeSaEFZI7felLHj # 9nlq4H/2EDRrY+7EnG1TWqtnuqDJAJf/7M0giiVxIk77XGX+USUNPOSG4NP/yc8E # D5p2GN23pUsvnI0jBZkyP3gyeXVNCNG5+KobwqJM3r6OjEiTRmLEVBw98YzG12bh # OY9ekMtVUKHi4Cvsf+2TtkDGRya0wX4uqm4UB1TtV1VUDoCWhYgEKBHp3ozCoVjB # J+ygbx7/jNfY53cpgEpKUBFH7rnOq1yQQ+ad5Ap5hbp4j6WSvPwdp1N3RCnkZzd/ # L50VIaySd+P6enAgPO5Mbt3kMMVd/eDGhQDWdzNToIjyhXBb5hUNfumg9AgdEwTh # rW/kKT39YLYWLO123hIJCy2CKU9nvoea9588ExkKb22v0ltrtDcAlWfCbZvZYxNN # wRzh+MFBt7Cd/bqk7HaJ0J/YyPToqImoUjNuBnBSDPqZQP2H4U8v/FoICQ0mm5kR # jZCmGLMEP1PiDlusjUjaW0iamHvXiSP8KEzaAbIxx5UUiTWTTkQm4CKY/xPxC9VQ # 0ygJqJVrKHlNrAY9u6ggJAXtorVwmC55z4ZqIVQH6cbzUYFMuJU= # =WpL4 # -----END PGP SIGNATURE----- # gpg: Signature made Tue 03 Oct 2023 19:30:54 EDT # gpg: using RSA key 2035F894B00AA3CF7CCDE1B76C1CD1287DB01100 # gpg: Good signature from "Warner Losh <[email protected]>" [unknown] # gpg: aka "Warner Losh <[email protected]>" [unknown] # gpg: aka "Warner Losh <[email protected]>" [unknown] # gpg: aka "Warner Losh <[email protected]>" [unknown] # gpg: aka "Warner Losh <[email protected]>" [unknown] # gpg: WARNING: This key is not certified with a trusted signature! # gpg: There is no indication that the signature belongs to the owner. # Primary key fingerprint: 2035 F894 B00A A3CF 7CCD E1B7 6C1C D128 7DB0 1100 * tag 'bsd-user-mmap-pull-request' of https://gitlab.com/bsdimp/qemu: (51 commits) bsd-user: Add stubs for vadvise(), sbrk() and sstk() bsd-user: Implement shmat(2) and shmdt(2) bsd-user: Implement shmctl(2) bsd-user: Implement shm_unlink(2) and shmget(2) bsd-user: Implement shm_open(2) bsd-user: Implement do_obreak function bsd-user: Implement mincore(2) bsd-user: Implment madvise(2) to match the linux-user implementation. bsd-user: Implement mlock(2), munlock(2), mlockall(2), munlockall(2), minherit(2) bsd-user: Implement msync(2) bsd-user: Implement mprotect(2) bsd-user: Implement mmap(2) and munmap(2) bsd-user: Introduce bsd-mem.h to the source tree bsd-user: Implement shmid_ds conversion between host and target. bsd-user: Implement ipc_perm conversion between host and target. bsd-user: Implement target_set_brk function in bsd-mem.c instead of os-syscall.c bsd-user: Add bsd-mem.c to meson.build bsd-user: Implement shm_rename(2) system call bsd-user: Implement shm_open2(2) system call bsd-user: Introduce freebsd/os-misc.h to the source tree ...

As docs/devel/loads-stores.rst states: ``GETPC()`` should be used with great care: calling it in other functions that are *not* the top level ``HELPER(foo)`` will cause unexpected behavior. Instead, the value of ``GETPC()`` should be read from the helper and passed if needed to the functions that the helper calls. Let's fix the GETPC() usage in Hexagon, making sure it's always called from top level helpers and passed down to the places where it's needed. There are a few snippets where that is not currently the case: - probe_store(), which is only called from two helpers, so it's easy to move GETPC() up. - mem_load*() functions, which are also called directly from helpers, but through the MEM_LOAD*() set of macros. Note that this are only used when compiling with --disable-hexagon-idef-parser. In this case, we also take this opportunity to simplify the code, unifying the mem_load*() functions. - HELPER(probe_hvx_stores), when called from another helper, ends up using its own GETPC() expansion instead of the top level caller.

Of the changes in this commit, the changes in `HELPER(commit_hvx_stores)()` are less obvious. They are required because of some macro invocations like SCATTER_OP_WRITE_TO_MEM(). e.g.: In file included from ../target/hexagon/op_helper.c:31: ../target/hexagon/mmvec/macros.h:205:18: error: declaration of ‘i’ shadows a previous local [-Werror=shadow=compatible-local] 205 | for (int i = 0; i < sizeof(MMVector); i += sizeof(TYPE)) { \ | ^ ../target/hexagon/op_helper.c:157:17: note: in expansion of macro ‘SCATTER_OP_WRITE_TO_MEM’ 157 | SCATTER_OP_WRITE_TO_MEM(uint16_t); | ^~~~~~~~~~~~~~~~~~~~~~~ ../target/hexagon/op_helper.c:135:9: note: shadowed declaration is here 135 | int i; | ^ In file included from ../target/hexagon/op_helper.c:31: ../target/hexagon/mmvec/macros.h:204:19: error: declaration of ‘ra’ shadows a previous local [-Werror=shadow=compatible-local] 204 | uintptr_t ra = GETPC(); \ | ^~ ../target/hexagon/op_helper.c:160:17: note: in expansion of macro ‘SCATTER_OP_WRITE_TO_MEM’ 160 | SCATTER_OP_WRITE_TO_MEM(uint32_t); | ^~~~~~~~~~~~~~~~~~~~~~~ ../target/hexagon/op_helper.c:134:15: note: shadowed declaration is here 134 | uintptr_t ra = GETPC(); | ^~ Reviewed-by: Matheus Tavares Bernardino <[email protected]> Signed-off-by: Brian Cain <[email protected]>
The typedef `vaddr` is shadowed by `vaddr` identifiers, so we rename the identifiers to avoid shadowing the type name. Signed-off-by: Brian Cain <[email protected]>
