aio: remove aio_disable_external() API
All callers now pass is_external=false to aio_set_fd_handler() and aio_set_event_notifier(). The aio_disable_external() API that temporarily disables fd handlers that were registered is_external=true is therefore dead code.
Remove aio_disable_external(), aio_enable_external(), and the is_external arguments to aio_set_fd_handler() and aio_set_event_notifier().
The entire test-fdmon-epoll test is removed because its sole purpose was testing aio_disable_external().

util/event-loop-base: Introduce options to set the thread pool size
The thread pool regulates itself: when idle, it kills threads until empty, when in demand, it creates new threads until full. This behaviour doesn't play well with latency sensitive workloads where the price of creating a new thread is too high. For example, when paired with qemu's '-mlock', or using safety features like SafeStack, creating a new thread has been measured take multiple milliseconds.
In order to mitigate this let's introduce a new 'EventLoopBase' property to set the thread pool size. The threads will be created during the pool's initialization or upon updating the property's value, remain available during its lifetime regardless of demand, and destroyed upon freeing it. A properly characterized workload will then be able to configure the pool to avoid any latency spikes.

This will permit tweaking the main loop's properties through qapi as well as through the command line using the '-object' keyword[1]. Only one instance of 'MainLoopClass' might be created at any time.
'EventLoopBaseClass' learns a new callback, 'can_be_deleted()' so as to mark 'MainLoop' as non-deletable.

Use g_new() & friends where that makes obvious sense
g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer, for two reasons. One, it catches multiplication overflowing size_t. Two, it returns T * rather than void *, which lets the compiler catch more type errors.

aio-posix: split poll check from ready handler
Adaptive polling measures the execution time of the polling check plus handlers called when a polled event becomes ready. Handlers can take a significant amount of time, making it look like polling was running for a long time when in fact the event handler was running for a long time.
For example, on Linux the io_submit(2) syscall invoked when a virtio-blk device's virtqueue becomes ready can take 10s of microseconds. This can exceed the default polling interval (32 microseconds) and cause adaptive polling to stop polling.
By excluding the handler's execution time from the polling check we make the adaptive polling calculation more accurate. As a result, the event loop now stays in polling mode where previously it would have fallen back to file descriptor monitoring.
The following data was collected with virtio-blk num-queues=2 event_idx=off using an IOThread. Before:
168k IOPS, IOThread syscalls:
9837.115 ( 0.020 ms): IO iothread1/620155 io_submit(ctx_id: 140512552468480, nr: 16, iocbpp: 0x7fcb9f937db0) = 16 9837.158 ( 0.002 ms): IO iothread1/620155 write(fd: 103, buf: 0x556a2ef71b88, count: 8) = 8 9837.161 ( 0.001 ms): IO iothread1/620155 write(fd: 104, buf: 0x556a2ef71b88, count: 8) = 8 9837.163 ( 0.001 ms): IO iothread1/620155 ppoll(ufds: 0x7fcb90002800, nfds: 4, tsp: 0x7fcb9f1342d0, sigsetsize: 8) = 3 9837.164 ( 0.001 ms): IO iothread1/620155 read(fd: 107, buf: 0x7fcb9f939cc0, count: 512) = 8 9837.174 ( 0.001 ms): IO iothread1/620155 read(fd: 105, buf: 0x7fcb9f939cc0, count: 512) = 8 9837.176 ( 0.001 ms): IO iothread1/620155 read(fd: 106, buf: 0x7fcb9f939cc0, count: 512) = 8 9837.209 ( 0.035 ms): IO iothread1/620155 io_submit(ctx_id: 140512552468480, nr: 32, iocbpp: 0x7fca7d0cebe0) = 32
174k IOPS (+3.6%), IOThread syscalls:
9809.566 ( 0.036 ms): IO iothread1/623061 io_submit(ctx_id: 140539805028352, nr: 32, iocbpp: 0x7fd0cdd62be0) = 32 9809.625 ( 0.001 ms): IO iothread1/623061 write(fd: 103, buf: 0x5647cfba5f58, count: 8) = 8 9809.627 ( 0.002 ms): IO iothread1/623061 write(fd: 104, buf: 0x5647cfba5f58, count: 8) = 8 9809.663 ( 0.036 ms): IO iothread1/623061 io_submit(ctx_id: 140539805028352, nr: 32, iocbpp: 0x7fd0d0388b50) = 32
Notice that ppoll(2) and eventfd read(2) syscalls are eliminated because the IOThread stays in polling mode instead of falling back to file descriptor monitoring.
As usual, polling is not implemented on Windows so this patch ignores the new io_poll_read() callback in aio-win32.c.

Merge remote-tracking branch 'remotes/dg-gitlab/tags/ppc-for-6.1-20210709' into staging ppc patch queue 2021-07-09 Here's a (probably) final pull request before the qemu-6.1 soft freeze. Includes: * Implementation of the new H_RPT_INVALIDATE hypercall * Virtual Open Firmware for pSeries and pegasos2 machine types. This is an experimental minimal Open Firmware implementation which works by delegating nearly everything to qemu itself via a special hypercall. * A number of cleanups to the ppc soft MMU code * Fix to handling of two-level radix mode translations for the powernv machine type * Update the H_GET_CPU_CHARACTERISTICS call with newly defined bits. This will allow more flexible handling of possible future CPU Spectre-like flaws * Correctly treat mtmsrd as an illegal instruction on BookE cpus * Firmware update for the ppce500 machine type # gpg: Signature made Fri 09 Jul 2021 06:16:42 BST # gpg: using RSA key 75F46586AE61A66CC44E87DC6C38CACA20D9B392 # gpg: Good signature from "David Gibson <david@gibson.dropbear.id.au>" [full] # gpg: aka "David Gibson (Red Hat) <dgibson@redhat.com>" [full] # gpg: aka "David Gibson (ozlabs.org) <dgibson@ozlabs.org>" [full] # gpg: aka "David Gibson (kernel.org) <dwg@kernel.org>" [unknown] # Primary key fingerprint: 75F4 6586 AE61 A66C C44E 87DC 6C38 CACA 20D9 B392 * remotes/dg-gitlab/tags/ppc-for-6.1-20210709: (33 commits) target/ppc: Support for H_RPT_INVALIDATE hcall linux-headers: Update spapr: Fix implementation of Open Firmware client interface target/ppc: Don't compile ppc_tlb_invalid_all without TCG ppc/pegasos2: Implement some RTAS functions with VOF ppc/pegasos2: Fix use of && instead of & ppc/pegasos2: Use Virtual Open Firmware as firmware replacement target/ppc/spapr: Update H_GET_CPU_CHARACTERISTICS L1D cache flush bits target/ppc: Allow virtual hypervisor on CPU without HV ppc/pegasos2: Introduce Pegasos2MachineState structure target/ppc: mtmsrd is an illegal instruction on BookE spapr: Implement Open Firmware client interface docs/system: ppc: Update ppce500 documentation with eTSEC support roms/u-boot: Bump ppce500 u-boot to v2021.07 to add eTSEC support target/ppc: change ppc_hash32_xlate to use mmu_idx target/ppc: introduce mmu-books.h target/ppc: changed ppc_hash64_xlate to use mmu_idx target/ppc: fix address translation bug for radix mmus target/ppc: Fix compilation with DEBUG_BATS debug option target/ppc: Fix compilation with FLUSH_ALL_TLBS debug option ...

util/async: add a human-readable name to BHs for debugging It can be difficult to debug issues with BHs in production environments. Although BHs can usually be identified by looking up their ->cb() function pointer, this requires debug information for the program. It is also not possible to print human-readable diagnostics about BHs because they have no identifier. This patch adds a name to each BH. The name is not unique per instance but differentiates between cb() functions, which is usually enough. It's done by changing aio_bh_new() and friends to macros that stringify cb. The next patch will use the name field when reporting leaked BHs.
