2022-03-16softmmu: List CPU types againPhilippe Mathieu-Daudé
Commit e0220bb5b2 made cpus.c target-agnostic but didn't notice the cpu_list() function is only defined in target-specific code in "cpu.h". Move list_cpus() declaration to "exec/cpu-common.h" because this function is not softmmu-specific and can also be used by user-mode, along with moving its implementation to cpu.c, which is compiled per target.

2022-03-15kvm/msi: do explicit commit when adding msi routesLongpeng(Mike)
We invoke the kvm_irqchip_commit_routes() for each addition to MSI route table, which is not efficient if we are adding lots of routes in some cases. This patch lets callers invoke the kvm_irqchip_commit_routes(), so the callers can decide how to optimize.

2022-03-15kvm-irqchip: introduce new API to support route changeLongpeng(Mike)
Paolo suggested adding the new API to support route changes [1].

2022-03-04os-posix: Add os_set_daemonize()Hanna Reitz
The daemonizing functions in os-posix (os_daemonize() and os_setup_post()) only daemonize the process if the static `daemonize` variable is set. Right now, it can only be set by os_parse_cmd_args(). In order to use os_daemonize() and os_setup_post() from the storage daemon to have it be daemonized, we need some other way to set this `daemonize` variable, because I would rather not tap into the system emulator's arg-parsing code. Therefore, this patch adds an os_set_daemonize() function, which will return an error on os-win32 (because daemonizing is not supported there).

2022-01-28rtc: Move RTC function prototypes to their own headerPeter Maydell
softmmu/rtc.c defines two public functions: qemu_get_timedate() and qemu_timedate_diff(). Currently we keep the prototypes for these in qemu-common.h, but most files don't need them. Move them to their own header, a new include/sysemu/rtc.h. Since the C files using these two functions did not need to include qemu-common.h for any other reason, we can remove those include lines when we add the include of the new rtc.h. The license for the .h file follows that of the softmmu/rtc.c where both the functions are defined.

2022-01-18hw/dma: Let dma_buf_read() / dma_buf_write() propagate MemTxResultPhilippe Mathieu-Daudé
Since commit 292e13142d2, dma_buf_rw() returns a MemTxResult type. Do not discard it, return it to the caller. Pass the previously returned value (the QEMUSGList residual size, which was rarely used) as an optional argument. With this new API, SCSIRequest::residual might now be accessed via a pointer. Since the size_t type does not have the same size on 32 and 64-bit host architectures, convert it to a uint64_t, which is big enough to hold the residual size, and the type is constant on both 32/64-bit hosts. Update the few dma_buf_read() / dma_buf_write() callers to the new API.

2021-12-15blockdev: Drop unused drive_get_next()Markus Armbruster
drive_get_next() is basically a bad idea. It returns the "next" block backend of a certain interface type. "Next" means bus=0,unit=N, where subsequent calls count N up from zero, per interface type. This lets you define unit numbers implicitly by execution order. If the order changes, or new calls appear "in the middle", unit numbers change. ABI break. Hard to spot in review. The previous commits eliminated all uses. Drop the function.

2021-11-02watchdog: remove select_watchdog_actionPaolo Bonzini
Instead of invoking select_watchdog_action from both HMP and command line, go directly from HMP to QMP and use QemuOpts as the intermediary for the command line. This makes -watchdog-action explicitly a shortcut for "-action watchdog", so that "-watchdog-action" and "-action watchdog" override each other based on the position on the command line; previously, "-action watchdog" always won.

2021-11-01KVM: introduce dirty_pages and kvm_dirty_ring_enabledHyman Huang(黄勇)
dirty_pages is used to calculate dirtyrate via dirty ring, when enabled, kvm-reaper will increase the dirty pages after gfns being dirtied. kvm_dirty_ring_enabled shows if kvm-reaper is working. dirtyrate thread could use it to check if measurement can base on dirty ring feature.

2021-10-20device_tree: Add qemu_fdt_add_pathYanan Wang
qemu_fdt_add_path() works like qemu_fdt_add_subnode(), except it also adds all missing subnodes from the given path. We'll use it in a coming patch where we will add cpu-map to the device tree. And we also tweak an error message of qemu_fdt_add_subnode().

2021-10-15block-backend: update blk_co_pwrite() and blk_co_pread() wrappersVladimir Sementsov-Ogievskiy
Make bytes argument int64_t to be consistent with modern block-layer. Callers should be OK with it as type becomes wider. What is inside functions? - Conversion from int64_t to size_t. Still, we can't have a buffer larger than SIZE_MAX, therefore bytes should not be larger than SIZE_MAX as well. Add an assertion. - Passing to blk_co_pwritev() / blk_co_preadv() which already has int64_t bytes argument.

2021-10-15block-backend: convert blk_aio_ functions to int64_t bytes paramterVladimir Sementsov-Ogievskiy
1. Convert bytes in BlkAioEmAIOCB: aio->bytes is only passed to already int64_t interfaces, and set in blk_aio_prwv, which is updated here. 2. For all updated functions the parameter type becomes wider so callers are safe. 3. In blk_aio_prwv we only store bytes to BlkAioEmAIOCB, which is updated here. 4. Other updated functions are wrappers on blk_aio_prwv. Note that blk_aio_preadv and blk_aio_pwritev become safer: before this commit, it's theoretically possible to pass qiov with size exceeding INT_MAX, which than converted to int argument of blk_aio_prwv. Now it's converted to int64_t which is a lot better. Still add assertions.

2021-10-15block-backend: convert blk_co_copy_range to int64_t bytesVladimir Sementsov-Ogievskiy
Function is updated so that parameter type becomes wider, so all callers should be OK with it. Look at blk_co_copy_range() itself: bytes is passed only to blk_check_byte_request() and bdrv_co_copy_range(), which already have int64_t bytes parameter, so we are OK. Note that requests exceeding INT_MAX are still restricted by blk_check_byte_request().

2021-10-15block-backend: convert blk_foo wrappers to use int64_t bytes parameterVladimir Sementsov-Ogievskiy
Convert blk_pdiscard, blk_pwrite_compressed, blk_pwrite_zeroes. These are just wrappers for functions with int64_t argument, so allow passing int64_t as well. Parameter type becomes wider so all callers should be OK with it. Note that requests exceeding INT_MAX are still restricted by blk_check_byte_request(). Note also that we don't (and are not going to) convert blk_pwrite and blk_pread: these functions return number of bytes on success, so to update them, we should change return type to int64_t as well, which will lead to investigating and updating all callers which is too much. So, blk_pread and blk_pwrite remain unchanged.
