2021-09-15block: Clarify that @bytes is no limit on *pnumHanna Reitz1-0/+9
.bdrv_co_block_status() implementations are free to return a *pnum that exceeds @bytes, because bdrv_co_block_status() in block/io.c will clamp *pnum as necessary. On the other hand, if drivers' implementations return values for *pnum that are as large as possible, our recently introduced block-status cache will become more effective. So, make a note in block_int.h that @bytes is no upper limit for *pnum.

2021-09-15block: block-status cache for data regionsHanna Reitz3-3/+195
As we have attempted before (https://lists.gnu.org/archive/html/qemu-devel/2019-01/msg06451.html, "file-posix: Cache lseek result for data regions"; https://lists.nongnu.org/archive/html/qemu-block/2021-02/msg00934.html, "file-posix: Cache next hole"), this patch seeks to reduce the number of SEEK_DATA/HOLE operations the file-posix driver has to perform. The main difference is that this time it is implemented as part of the general block layer code. The problem we face is that on some filesystems or in some circumstances, SEEK_DATA/HOLE is unreasonably slow. Given the implementation is outside of qemu, there is little we can do about its performance. We have already introduced the want_zero parameter to bdrv_co_block_status() to reduce the number of SEEK_DATA/HOLE calls unless we really want zero information; but sometimes we do want that information, because for files that consist largely of zero areas, special-casing those areas can give large performance boosts. So the real problem is with files that consist largely of data, so that inquiring the block status does not gain us much performance, but where such an inquiry itself takes a lot of time. To address this, we want to cache data regions. Most of the time, when bad performance is reported, it is in places where the image is iterated over from start to end (qemu-img convert or the mirror job), so a simple yet effective solution is to cache only the current data region. (Note that only caching data regions but not zero regions means that returning false information from the cache is not catastrophic: Treating zeroes as data is fine. While we try to invalidate the cache on zero writes and discards, such incongruences may still occur when there are other processes writing to the image.) We only use the cache for nodes without children (i.e. protocol nodes), because that is where the problem is: Drivers that rely on block-status implementations outside of qemu (e.g. SEEK_DATA/HOLE).

2021-09-15block: Drop BDS comment regarding bdrv_append()Hanna Reitz1-6/+0
There is a comment above the BDS definition stating care must be taken to consider handling newly added fields in bdrv_append(). Actually, this comment should have said "bdrv_swap()" as of 4ddc07cac (nine years ago), and in any case, bdrv_swap() was dropped in 8e419aefa (six years ago). So no such care is necessary anymore.

2021-09-15gluster: Align block-status tailMax Reitz1-0/+16
gluster's block-status implementation is basically a copy of that in block/file-posix.c, there is only one thing missing, and that is aligning trailing data extents to the request alignment (as added by commit 9c3db310ff0). Note that 9c3db310ff0 mentions that "there seems to be no other block driver that sets request_alignment and [...]", but while block/gluster.c does indeed not set request_alignment, block/io.c's bdrv_refresh_limits() will still default to an alignment of 512 because block/gluster.c does not provide a byte-aligned read function. Therefore, unaligned tails can conceivably occur, and so we should apply the change from 9c3db310ff0 to gluster's block-status implementation.

2021-09-14tcg/arm: Fix tcg_out_vec_op function signatureJose R. Ziviani1-1/+2
Commit 5e8892db93 fixed several function signatures but tcg_out_vec_op for arm is missing. It causes a build error on armv6 and armv7: tcg-target.c.inc:2718:42: error: argument 5 of type 'const TCGArg *' {aka 'const unsigned int *'} declared as a pointer [-Werror=array-parameter=] const TCGArg *args, const int *const_args) ~~~~~~~~~~~~~~^~~~ ../tcg/tcg.c:120:41: note: previously declared as an array 'const TCGArg[16]' {aka 'const unsigned int[16]'} const TCGArg args[TCG_MAX_OP_ARGS], ~~~~~~~~~~~~~~^~~~ Signed-off-by: Jose R.

2021-09-14accel/tcg: Clear PAGE_WRITE before translationIlya Leoshkevich4-41/+97
translate_insn() implementations fetch instruction bytes piecemeal, which can cause qemu-user to generate inconsistent translations if another thread modifies them concurrently [1]. Fix by making pages containing translated instruction non-writable right before loading instruction bytes from them.

2021-09-14gitlab-ci: Make more custom runner jobs manual, and don't allow failurePeter Maydell1-12/+8
Currently we define a lot of jobs for our custom runners: for both aarch64 and s390x we have - all-linux-static - all - alldbg - clang (manual) - tci - notcg (manual) This is overkill. The main reason to run on these hosts is to get coverage for the host architecture; we can leave the handling of differences like debug vs non-debug to the x86 CI jobs. The jobs are also generally running OK; they occasionally fail due to timeouts, which is likely because we're overloading the machine by asking it to run 4 CI jobs at once plus the ad-hoc CI. Remove the 'allow_failure' tag from all these jobs, and switch the s390x-alldbg, aarch64-all, s390x-tci and aarch64-tci jobs to manual. (We keep -all on s390x and -alldbg on aarch64 just for diversity of coverage.) This will let us make the switch for s390x and aarch64 hosts from the ad-hoc CI to gitlab.
