2016-07-13block/qdev: Allow configuring rerror/werror with qdev propertiesKevin Wolf1-0/+1
The rerror/werror policies are implemented in the devices, so that's where they should be configured. In comparison to the old options in -drive, the qdev properties are only added to those devices that actually support them. If the option isn't given (or "auto" is specified), the setting of the BlockBackend is used for compatibility with the old options. For block jobs, "auto" is the same as "enospc".

2016-07-13block/qdev: Allow configuring WCE with qdev propertiesKevin Wolf1-0/+1
As cache.writeback is a BlockBackend property and as such more related to the guest device than the BlockDriverState, we already removed it from the blockdev-add interface. This patch adds the new way to set it, as a qdev property of the corresponding guest device.

2016-03-22include/qemu/osdep.h: Don't include qapi/error.hMarkus Armbruster1-0/+1
Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the Error typedef. Since then, we've moved to include qemu/osdep.h everywhere. Its file comment explains: "To avoid getting into possible circular include dependencies, this file should not include any other QEMU headers, with the exceptions of config-host.h, compiler.h, os-posix.h and os-win32.h, all of which are doing a similar job to this file and are under similar constraints." qapi/error.h doesn't do a similar job, and it doesn't adhere to similar constraints: it includes qapi-types.h. That's in excess of 100KiB of crap most .c files don't actually need. Add the typedef to qemu/typedefs.h, and include that instead of qapi/error.h. Include qapi/error.h in .c files that need it and don't get it now. Include qapi-types.h in qom/object.h for uint16List. Update scripts/clean-includes accordingly. Update it further to match reality: replace config.h by config-target.h, add sysemu/os-posix.h, sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h comment quoted above similarly. This reduces the number of objects depending on qapi/error.h from "all of them" to less than a third. Unfortunately, the number depending on qapi-types.h shrinks only a little. More work is needed for that one. Signed-off-by: Markus Armbruster <armbru@redhat.com> [Fix compilation without the spice devel packages. - Paolo] Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2016-02-08qom: Swap 'name' next to visitor in ObjectPropertyAccessorEric Blake1-4/+4
Similar to the previous patch, it's nice to have all functions in the tree that involve a visitor and a name for conversion to or from QAPI to consistently stick the 'name' parameter next to the Visitor parameter.

2016-02-08qapi: Swap visit_* arguments for consistent 'name' placementEric Blake1-2/+2
JSON uses "name":value, but many of our visitor interfaces were called with visit_type_FOO(v, &value, name, errp). This can be a bit confusing to have to mentally swap the parameter order to match JSON order. It's particularly bad for visit_start_struct(), where the 'name' parameter is smack in the middle of the otherwise-related group of 'obj, kind, size' parameters! It's time to do a global swap of the parameter ordering, so that the 'name' parameter is always immediately after the Visitor argument. Additional reason in favor of the swap: the existing include/qjson.h prefers listing 'name' first in json_prop_*(), and I have plans to unify that file with the qapi visitors; listing 'name' first in qapi will minimize churn to the (admittedly few) qjson.h clients. Later patches will then fix docs, object.h, visitor-impl.h, and those clients to match. Done by first patching scripts/qapi*.py by hand to make generated files do what I want, then by running the following Coccinelle script to affect the rest of the code base: $ spatch --sp-file script `git grep -l '\bvisit_' -- '**/*.[ch]'` I then had to apply some touchups (Coccinelle insisted on TAB indentation in visitor.h, and botched the signature of visit_type_enum() by rewriting 'const char *const strings[]' to the syntactically invalid 'const char*const[] strings'). The movement of parameters is sufficient to provoke compiler errors if any callers were missed. // Part 1: Swap declaration order @@ type TV, TErr, TObj, T1, T2; identifier OBJ, ARG1, ARG2; @@ void visit_start_struct -(TV v, TObj OBJ, T1 ARG1, const char *name, T2 ARG2, TErr errp) +(TV v, const char *name, TObj OBJ, T1 ARG1, T2 ARG2, TErr errp) { ... } @@ type bool, TV, T1; identifier ARG1; @@ bool visit_optional -(TV v, T1 ARG1, const char *name) +(TV v, const char *name, T1 ARG1) { ... } @@ type TV, TErr, TObj, T1; identifier OBJ, ARG1; @@ void visit_get_next_type -(TV v, TObj OBJ, T1 ARG1, const char *name, TErr errp) +(TV v, const char *name, TObj OBJ, T1 ARG1, TErr errp) { ... } @@ type TV, TErr, TObj, T1, T2; identifier OBJ, ARG1, ARG2; @@ void visit_type_enum -(TV v, TObj OBJ, T1 ARG1, T2 ARG2, const char *name, TErr errp) +(TV v, const char *name, TObj OBJ, T1 ARG1, T2 ARG2, TErr errp) { ... } @@ type TV, TErr, TObj; identifier OBJ; identifier VISIT_TYPE =~ "^visit_type_"; @@ void VISIT_TYPE -(TV v, TObj OBJ, const char *name, TErr errp) +(TV v, const char *name, TObj OBJ, TErr errp) { ... } // Part 2: swap caller order @@ expression V, NAME, OBJ, ARG1, ARG2, ERR; identifier VISIT_TYPE =~ "^visit_type_"; @@ ( -visit_start_struct(V, OBJ, ARG1, NAME, ARG2, ERR) +visit_start_struct(V, NAME, OBJ, ARG1, ARG2, ERR) | -visit_optional(V, ARG1, NAME) +visit_optional(V, NAME, ARG1) | -visit_get_next_type(V, OBJ, ARG1, NAME, ERR) +visit_get_next_type(V, NAME, OBJ, ARG1, ERR) | -visit_type_enum(V, OBJ, ARG1, ARG2, NAME, ERR) +visit_type_enum(V, NAME, OBJ, ARG1, ARG2, ERR) | -VISIT_TYPE(V, OBJ, NAME, ERR) +VISIT_TYPE(V, NAME, OBJ, ERR) ) Signed-off-by: Eric Blake <eblake@redhat.com> Reviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com> Message-Id: <1454075341-13658-19-git-send-email-eblake@redhat.com> Signed-off-by: Markus Armbruster <armbru@redhat.com>

2015-03-10BlockConf: Call backend functions to detect geometry and blocksizesEkaterina Tumanova1-0/+1
geometry: hd_geometry_guess function autodetects the drive geometry. This patch adds a block backend call, that probes the backing device geometry. If the inner driver method is implemented and succeeds (currently only for DASDs), the blkconf_geometry will pass-through the backing device geometry. Otherwise will fallback to old logic. blocksize: This patch initializes blocksize properties to 0. In order to set the property a blkconf_blocksizes was introduced. If user didn't set physical or logical blocksize, it will retrieve its value from a driver (only succeeds for DASD), otherwise it will set default 512 value. The blkconf_blocksizes call was added to all users of BlkConf.

Our IDE emulation can't handle logical block sizes other than 512. Check for it. The original assumption was that other values would silently be ignored (which is bad enough), but it's not quite true: The physical block size is exposed in IDENTIFY DEVICE as a multiple of the logical block size. Setting a logical block size therefore also corrupts the physical block size (4096/4096 doesn't silently downgrade to 4096/512, but 512/512).

2014-10-20blockdev: Fix blockdev-add not to create DriveInfoMarkus Armbruster1-1/+1
blockdev_init() always creates a DriveInfo, but only drive_new() fills it in. qmp_blockdev_add() leaves it blank. This results in a drive with type = IF_IDE, bus = 0, unit = 0. Screwed up in commit ee13ed1c. Board initialization code looking for IDE drive (0,0) can pick up one of these bogus drives. The QMP command has to execute really early to be visible. Not sure how likely that is in practice. Fix by creating DriveInfo in drive_new(). Block backends created by blockdev-add don't get one. Breaks the test for "has been created by qmp_blockdev_add()" in blockdev_mark_auto_del() and do_drive_del(), because it changes the value of dinfo && !dinfo->enable_auto_del from true to false. Simply test !dinfo instead. Leaves DriveInfo member enable_auto_del unused. Drop it. A few places assume a block backend always has a DriveInfo. Fix them up.

2014-10-20hw: Convert from BlockDriverState to BlockBackend, mostlyMarkus Armbruster1-6/+5
Device models should access their block backends only through the block-backend.h API. Convert them, and drop direct includes of inappropriate headers. Just four uses of BlockDriverState are left: * The Xen paravirtual block device backend (xen_disk.c) opens images itself when set up via xenbus, bypassing blockdev.c. I figure it should go through qmp_blockdev_add() instead. * Device model "usb-storage" prompts for keys. No other device model does, and this one probably shouldn't do it, either. * ide_issue_trim_cb() uses bdrv_aio_discard() instead of blk_aio_discard() because it fishes its backend out of a BlockAIOCB, which has only the BlockDriverState. * PC87312State has an unused BlockDriverState[] member.

We identify devices by their Open Firmware device paths. The encoding of bus numbers is incorrect: idebus_get_fw_dev_path() formats them in decimal, while SeaBIOS uses hexadecimal. With bus number > 9, SeaBIOS will miss the bootindex (lucky case), or apply it to another device (unlucky case). Bug can't bite right now: ich9-ahci has six ports, and the sysbus-ahci created by Calxeda Highbank has just one. Fix it anyway, by changing %d to %x.

2012-06-18qdev: Move bus properties to abstract superclassesPaolo Bonzini1-1/+1
In qdev, each bus in practice identified an abstract superclass, but this was mostly hidden. In QOM, instead, these abstract classes are explicit so we can move bus properties there. All bus property walks are removed, and all device property walks are changed to look along the class hierarchy instead. We would have duplicates if class A defines some properties and its subclass B does not define any, because class_b->props will be left equal to class_a->props. The solution here is to reintroduce the class_base_init TypeInfo callback, that was present in one of the early QOM versions but removed (on my request...) before committing. This breaks global bus properties, an obscure feature when used with the command-line which is actually useful and used when used by backwards-compatible machine types. So this patch also adjusts the global bus properties in hw/pc_piix.c to refer to the abstract class. Globals and other properties must be modified in the same patch to avoid complications related to initialization ordering.

2012-04-05ide: Adds wwn=hex qdev optionFloris Bos1-1/+2
Allow the user to specify a disk's World Wide Name. Linux guests can address disks by their unique World Wide Name number (e.g. /dev/disk/by-id/wwn-0x5001517959123522). This patch adds support for assigning a World Wide Name number to a virtual IDE disk. Cc: kwolf@redhat.com Signed-off-by: Floris Bos <dev@noc-ps.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2012-04-05ide: Add "model=s" qdev optionFloris Bos1-2/+4
Allow the user to override the default disk model name "QEMU HARDDISK". Some Linux distributions use the /dev/disk/by-id/scsi-SATA_name-of-disk- model_serial addressing scheme when refering to partitions in /etc/fstab and elsewhere. This causes problems when starting a disk image taken from an existing physical server under qemu, because when running under qemu name-of-disk-model is always "QEMU HARDDISK". This patch introduces a model=s option which in combination with the existing serial=s option can be used to fake the disk the operating system was previously on, allowing the OS to boot properly.

2012-02-15qom: Unify type registrationAndreas Färber1-2/+3
Replace device_init() with generalized type_init(). While at it, unify naming convention: type_init([$prefix_]register_types) Also, type_init() is a function, so add preceding blank line where necessary and don't put a semicolon after the closing brace.

2012-02-03qdev: kill off DeviceInfoAnthony Liguori1-1/+1
It is no longer used in the tree since everything is done natively through QEMU Object Model. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-02-03qdev: register all types natively through QEMU Object ModelAnthony Liguori1-40/+53
This was done in a mostly automated fashion. I did it in three steps and then rebased it into a single step which avoids repeatedly touching every file in the tree. The first step was a sed-based addition of the parent type to the subclass registration functions. The second step was another sed-based removal of subclass registration functions while also adding virtual functions from the base class into a class_init function as appropriate. Finally, a python script was used to convert the DeviceInfo structures and qdev_register_subclass functions to TypeInfo structures, class_init functions, and type_register_static calls. We are almost fully converted to QOM after this commit. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
