2021-05-20Merge remote-tracking branch 'remotes/bsdimp/tags/pull-bsd-user-20210511' ↵Peter Maydell
into staging pull-bsd-user-20210511 is the next round of cleanups to bsd-user in merging the bsd-user fork into qemu. It contains a number of style commits, as well as 3 commits that start to change things: Some unused files are deleted, building the sparc and sparc64 targets are removed, and a structure is renamed. The next set of pull requests will start to execute the following plan: 1. Move existing code around to have a structure similar to the bsd-user fork. 2. Incrementally merge groups of system calls, focused on making x86 work. 3. Once the groups of system calls are all merged, additional platforms will be added back. 4. Concurrently, as changes are requested as part of the merge happen, those changes will be merged into the fork. An experimental merge to tip of master is under test and is what will be updated. 5. Eventually, there will be no diference, and the bsd-user fork will only be a staging area for cutting-edge features prior to upstreaming into qemu mainline. The bsd-user code in qemu has a lot of style issues. This cleans up a number in the files touched. However, the checkpatch.pl detects some incremental issues in the commits. The following are expected, but are corrected in later hashes in this branch. MAINTAINERS does not need to be updated, since all the files added or deleted are covered under existing regexp in MAINTAINERS.

2021-02-16exec: Use cpu_untagged_addr in g2h; split out g2h_untaggedRichard Henderson
Use g2h_untagged in contexts that have no cpu, e.g. the binary loaders that operate before the primary cpu is created. As a colollary, target_mmap and friends must use untagged addresses, since they are used by the loaders. Use g2h_untagged on values returned from target_mmap, as the kernel never applies a tag itself. Use g2h_untagged on all pc values. The only current user of tags, aarch64, removes tags from code addresses upon branch, so "pc" is always untagged. Use g2h with the cpu context on hand wherever possible. Use g2h_untagged in lock_user, which will be updated soon.

2020-03-16misc: Replace zero-length arrays with flexible array member (automatic)Philippe Mathieu-Daudé
Description copied from Linux kernel commit from Gustavo A. R. Silva (see [3]): --v-- description start --v-- The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member [1], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being unadvertenly introduced [2] to the Linux codebase from now on. --^-- description end --^-- Do the similar housekeeping in the QEMU codebase (which uses C99 since commit 7be41675f7cb). All these instances of code were found with the help of the following Coccinelle script: @@ identifier s, m, a; type t, T; @@ struct s { ... t m; - T a[0]; + T a[]; }; @@ identifier s, m, a; type t, T; @@ struct s { ... t m; - T a[0]; + T a[]; } QEMU_PACKED; [1] https://gcc.gnu.org/onlinedocs/gcc/Zero-Length.html [2] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=76497732932f [3] https://git.kernel.org/pub/scm/linux/kernel/git/gustavoars/linux.git/commit/?id=17642a2fbd2c1 Inspired-by: Gustavo A.

2020-01-15tcg: Search includes from the project root source directoryPhilippe Mathieu-Daudé
We currently search both the root and the tcg/ directories for tcg files: $ git grep '#include "tcg/' | wc -l 28 $ git grep '#include "tcg[^/]' | wc -l 94 To simplify the preprocessor search path, unify by expliciting the tcg/ directory. Patch created mechanically by running: $ for x in \ tcg.h tcg-mo.h tcg-op.h tcg-opc.h \ tcg-op-gvec.h tcg-gvec-desc.h; do \ sed -i "s,#include \"$x\",#include \"tcg/$x\"," \ $(git grep -l "#include \"$x\""); \ done Acked-by: David Gibson <david@gibson.dropbear.id.au> (ppc parts) Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Reviewed-by: Alistair Francis <alistair.francis@wdc.com> Reviewed-by: Stefan Weil <sw@weilnetz.de> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Philippe Mathieu-Daudé <philmd@redhat.com> Message-Id: <20200101112303.20724-2-philmd@redhat.com> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2019-12-19linux-user: log page table changes under -d pageAlex Bennée
The CPU_LOG_PAGE flag is woefully underused and could stand to do extra duty tracking page changes. If the user doesn't want to see the details as things change they still have the tracepoints available. We push the locking into log_page_dump and pass a reason for the banner text.

2019-10-28*-user: plugin syscallsEmilio G. Cota
To avoid too much duplication add a wrapper that the existing trace and the new plugin calls can live in. We could move the -strace code here as well but that is left for a future series as the code is subtly different between the bsd and linux. Signed-off-by: Emilio G.
