* | Revert "hostmem: fix QEMU crash by 'info memdev'"Markus Armbruster2017-03-211-14/+8Star
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 1454d33f0507cb54d62ed80f494884157c9e7130. The string input visitor regression fixed in the previous commit made visit_type_uint16List() fail on empty input. query_memdev() calls it via object_property_get_uint16List(). Because it doesn't expect it to fail, it passes &error_abort, and duly crashes. Commit 1454d33 "fixes" this crash by making host_memory_backend_get_host_nodes() return a list containing just MAX_NODES instead of the empty list. Papers over the regression, and leads to bogus "info memdev" output, as shown below; revert. I suspect that if we had bisected the crash back then, we would have found and fixed the actual bug instead of papering over it. To reproduce, run HMP command "info memdev" with $ qemu-system-x86_64 --nodefaults -S -display none -monitor stdio -object memory-backend-ram,id=mem1,size=4k With this commit, "info memdev" prints memory backend: mem1 size: 4096 merge: true dump: true prealloc: false policy: default host nodes: exactly like before commit 74f24cb. Between commit 1454d33 and this commit, it prints memory backend: mem1 size: 4096 merge: true dump: true prealloc: false policy: default host nodes: 128 The last line is bogus. Between commit 74f24cb and 1454d33, it crashes like this: Unexpected error in parse_str() at /work/armbru/tmp/qemu/qapi/string-input-visitor.c:126: Parameter 'null' expects an int64 value or range Aborted (core dumped) Cc: Xiao Guangrong <guangrong.xiao@linux.intel.com> Cc: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Markus Armbruster <armbru@redhat.com> Message-Id: <1490026424-11330-3-git-send-email-armbru@redhat.com> Reviewed-by: Michael Roth <mdroth@linux.vnet.ibm.com> Reviewed-by: Eric Blake <eblake@redhat.com>
* mem-prealloc: reduce large guest start-up and migration time.Jitendra Kolhe2017-03-141-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using "-mem-prealloc" option for a large guest leads to higher guest start-up and migration time. This is because with "-mem-prealloc" option qemu tries to map every guest page (create address translations), and make sure the pages are available during runtime. virsh/libvirt by default, seems to use "-mem-prealloc" option in case the guest is configured to use huge pages. The patch tries to map all guest pages simultaneously by spawning multiple threads. Currently limiting the change to QEMU library functions on POSIX compliant host only, as we are not sure if the problem exists on win32. Below are some stats with "-mem-prealloc" option for guest configured to use huge pages. ------------------------------------------------------------------------ Idle Guest | Start-up time | Migration time ------------------------------------------------------------------------ Guest stats with 2M HugePage usage - single threaded (existing code) ------------------------------------------------------------------------ 64 Core - 4TB | 54m11.796s | 75m43.843s 64 Core - 1TB | 8m56.576s | 14m29.049s 64 Core - 256GB | 2m11.245s | 3m26.598s ------------------------------------------------------------------------ Guest stats with 2M HugePage usage - map guest pages using 8 threads ------------------------------------------------------------------------ 64 Core - 4TB | 5m1.027s | 34m10.565s 64 Core - 1TB | 1m10.366s | 8m28.188s 64 Core - 256GB | 0m19.040s | 2m10.148s ----------------------------------------------------------------------- Guest stats with 2M HugePage usage - map guest pages using 16 threads ----------------------------------------------------------------------- 64 Core - 4TB | 1m58.970s | 31m43.400s 64 Core - 1TB | 0m39.885s | 7m55.289s 64 Core - 256GB | 0m11.960s | 2m0.135s ----------------------------------------------------------------------- Changed in v2: - modify number of memset threads spawned to min(smp_cpus, 16). - removed 64GB memory restriction for spawning memset threads.

* char: remove class kind fieldMarc-André Lureau2017-01-313-3/+0Star
| | | | | | | | | | | | | | | | The class kind is necessary to lookup the chardev name in qmp_chardev_add() after calling qemu_chr_new_from_opts() and to set the appropriate ChardevBackend (mainly to free the right fields). qemu_chr_new_from_opts() can be changed to use a non-qmp function using the chardev class typename. Introduce qemu_chardev_add() to be called from qemu_chr_new_from_opts() and remove the class chardev kind field. Set the backend->type in the parse callback (when non-common fields are added).

* chardev: qom-ifyMarc-André Lureau2017-01-273-75/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | Turn Chardev into Object. qemu_chr_alloc() is replaced by the qemu_chardev_new() constructor. It will call qemu_char_open() to open/intialize the chardev with the ChardevCommon *backend settings. The CharDriver::create() callback is turned into a ChardevClass::open() which is called from the newly introduced qemu_chardev_open(). "chardev-gdb" and "chardev-hci" are internal chardev and aren't creatable directly with -chardev. Use a new internal flag to disable them. We may want to use TYPE_USER_CREATABLE interface instead, or perhaps allow -chardev usage. Although in general we keep typename and macros private, unless the type is being used by some other file, in this patch, all types and common helper macros for qemu-char.c are in char.h. This is to help transition now (some types must be declared early, while some aren't shared) and when splitting in several units. This is to be improved later.

* Defer BrlAPI tty acquisition to when guest starts using deviceSamuel Thibault2016-10-281-32/+49
| | | | | | | | | | We do not want to catch the BrlAPI input/ouput immediately, but only when the guest has started discussing withour virtual device. This notably fixes input before the guest driver has started. Signed-off-by: Samuel Thibault <samuel.thibault@ens-lyon.org> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

* char: remove explicit_be_open from CharDriverStateMarc-André Lureau2016-10-243-1/+4
| | | | | | | | | | It's only used in qmp_chardev_add(), so use a create() argument instead. Also switched to typedef functions for CharDriverParse/CharDriverCreate.

| | | | | | | | | No need to keep explicit_fe_open around if it affects only a qemu_chr_fe_set_handlers(). Use an additional argument instead.

* char: replace qemu_chr_claim/release with qemu_chr_fe_init/deinitMarc-André Lureau2016-10-241-9/+1Star
| | | | | | | | | | | | | | | Now that all front end use qemu_chr_fe_init(), we can move chardev claiming in init(), and add a function deinit() to release the chardev and cleanup handlers. The qemu_chr_fe_claim_no_fail() for property are gone, since the property will raise an error instead. In other cases, where there is already an error path, an error is raised instead. Finally, other cases are handled by &error_abort in qemu_chr_fe_init().

| | | | | | | | | | | | | To do the conversion, the file_backend_class_init() was moved after the getter/setter functions. The old file_backend_instance_init() function was removed because it is not needed anymore. The NULL errp arguments on the property registration calls were changed to &error_abort.
