* pvrdma: wean code off pvrdma_ring.h kernel headerCornelia Huck2021-03-155-28/+37
| | | | | | | | | | | | | | | | | | | | The pvrdma code relies on the pvrdma_ring.h kernel header for some basic ring buffer handling. The content of that header isn't very exciting, but contains some (q)atomic_*() invocations that (a) cause manual massaging when doing a headers update, and (b) are an indication that we probably should not be importing that header at all. Let's reimplement the ring buffer handling directly in the pvrdma code instead. This arguably also improves readability of the code. Importing the header can now be dropped.

* | hw/rdma: Replace QList by GQueueMarkus Armbruster2020-12-194-26/+30
|/ | | | | | | | | | | | | | | | | | RdmaProtectedQList provides a thread-safe queue of int64_t on top of a QList. rdma_protected_qlist_destroy() calls qlist_destroy_obj() directly. qlist_destroy_obj() is actually for use by qobject_destroy() only. The next commit will make that obvious. The minimal fix would be calling qobject_unref() instead. But QList is actually a bad fit here. It's designed for representing JSON arrays. We're better off with a GQueue here. Replace.

* qemu/atomic.h: rename atomic_ to qatomic_Stefan Hajnoczi2020-09-233-12/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <stdatomic.h> 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 <stdatomic.h>. Prefix QEMU's APIs with 'q' so that atomic.h and <stdatomic.h> 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 '\<atomic\(64\)\?_[a-z0-9_]\+' include/qemu/atomic.h | \ sort -u >/tmp/changed_identifiers $ for identifier in $(</tmp/changed_identifiers); do sed -i "s%\<$identifier\>%q$identifier%g" \ $(git grep -I -l "\<$identifier\>") done I manually fixed line-wrap issues and misaligned rST tables.

* trace: switch position of headers to what Meson requiresPaolo Bonzini2020-08-212-0/+2
| | | | | | | | | | | | | | | | | Meson doesn't enjoy the same flexibility we have with Make in choosing the include path. In particular the tracing headers are using $(build_root)/$(<D). In order to keep the include directives unchanged, the simplest solution is to generate headers with patterns like "trace/trace-audio.h" and place forwarding headers in the source tree such that for example "audio/trace.h" includes "trace/trace-audio.h". This patch is too ugly to be applied to the Makefiles now. It's only a way to separate the changes to the tracing header files from the Meson rewrite of the tracing logic.

* hw/rdma: Skip data-path mr_id translationYuval Shaia2020-03-213-19/+20
| | | | | | | | | | | | | | | | | | | | | | With the change made in commit 68b89aee71 ("Utilize ibv_reg_mr_iova for memory registration") the MR emulation is no longer needed in order to translate the guest addresses into host addresses. With that, the next obvious step is to skip entirely the processing in data-path. To accomplish this, return the backend's lkey to driver so we will not need to do the emulated mr_id to backend mr_id translation in data-path. The function build_host_sge_array is still called in data-path but only for backward computability with statistics collection. While there, as a cosmetic change to make the code cleaner - make one copy of the function rdma_backend_create_mr and leave the redundant guest_start argument in the legacy code.
