2016-03-22include/qemu/osdep.h: Don't include qapi/error.hMarkus Armbruster
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 Blake
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. Done by manually changing include/qom/object.h and qom/object.c, then running this Coccinelle script and touching up the fallout (Coccinelle insisted on adding some trailing whitespace). @ rule1 @ identifier fn; typedef Object, Visitor, Error; identifier obj, v, opaque, name, errp; @@ void fn - (Object *obj, Visitor *v, void *opaque, const char *name, + (Object *obj, Visitor *v, const char *name, void *opaque, Error **errp) { ... } @@ identifier rule1.fn; expression obj, v, opaque, name, errp; @@ fn(obj, v, - opaque, name, + name, opaque, errp) Signed-off-by: Eric Blake <eblake@redhat.com> Reviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com> Message-Id: <1454075341-13658-20-git-send-email-eblake@redhat.com> Signed-off-by: Markus Armbruster <armbru@redhat.com>
2016-02-08qapi: Swap visit_* arguments for consistent 'name' placementEric Blake
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>

2016-01-13isa: Clean up error handling around isa_bus_new()Markus Armbruster
We can have at most one ISA bus. If you try to create another one, isa_bus_new() complains to stderr and returns null. isa_bus_new() is called in two contexts, machine's init() and device's realize() methods. Since complaining to stderr is not proper in the latter context, convert isa_bus_new() to Error. Machine's init(): * mips_jazz_init(), called from the init() methods of machines "magnum" and "pica" * mips_r4k_init(), the init() method of machine "mips" * pc_init1() called from the init() methods of non-q35 PC machines * typhoon_init(), called from clipper_init(), the init() method of machine "clipper" These callers always create the first ISA bus, hence isa_bus_new() can't fail. Simply pass &error_abort. Device's realize(): * i82378_realize(), of PCI device "i82378" * ich9_lpc_realize(), of PCI device "ICH9-LPC" * pci_ebus_realize(), of PCI device "ebus" * piix3_realize(), of PCI device "pci-piix3", abstract parent of "PIIX3" and "PIIX3-xen" * piix4_realize(), of PCI device "PIIX4" * vt82c686b_realize(), of PCI device "VT82C686B" Propagate the error. Note that these devices are typically created only by machine init() methods with qdev_init_nofail() or similar. If we screwed up and created an ISA bus before that call, we now give up right away. Before, we'd hobble on, and typically die in isa_bus_irqs(). Similar if someone finds a way to hot-plug one of these critters. Cc: Richard Henderson <rth@twiddle.net> Cc: "Michael S.

2015-10-22hw/isa/lpc_ich9: inject the SMI on the VCPU that is writing to APM_CNTLaszlo Ersek
Commit 4d00636e97b7 ("ich9: Add the lpc chip", Nov 14 2012) added the ich9_apm_ctrl_changed() ioport write callback function such that it would inject the SMI, in response to a write to the APM_CNT register, on the first CPU, invariably. Since this register is used by guest code to trigger an SMI synchronously, the interrupt should be injected on the VCPU that is performing the write. apm_ioport_writeb() is the .write callback of the "apm_ops" MemoryRegionOps [hw/isa/apm.c]; it is parametrized to call ich9_apm_ctrl_changed() by ich9_lpc_init() [hw/isa/lpc_ich9.c], via apm_init(). Therefore this change affects no other board. ich9_generate_smi() is an unrelated function that is called by the TCO watchdog; a watchdog is likely in its right to (asynchronously) inject interrupts on the first CPU only. This patch allows the combined edk2/OVMF SMM driver stack to work with multiple VCPUs on TCG, using both qemu-system-i386 and qemu-system-x86_64.

2015-07-08ich9: implement strap SPKR pin logicPaulo Alcantara
If the signal is sampled high, this indicates that the system is strapped to the "No Reboot" mode (ICH9 will disable the TCO Timer system reboot feature). The status of this strap is readable via the NO_REBOOT bit (CC: offset 0x3410:bit 5). The NO_REBOOT bit is set when SPKR pin on ICH9 is sampled high. This bit may be set or cleared by software if the strap is sampled low but may not override the strap when it indicates "No Reboot". This patch implements the logic where hardware has ability to set SPKR pin through a property named "noreboot" and it's sampled high by default.

2015-07-07ich9: add TCO interface emulationPaulo Alcantara
This interface provides some registers within a 32-byte range and can be acessed through PCI-to-LPC bridge interface (PMBASE + 0x60). It's commonly used as a watchdog timer to detect system lockups through SMIs that are generated -- if TCO_EN bit is set -- on every timeout. If NO_REBOOT bit is not set in GCS (General Control and Status register), the system will be resetted upon second timeout if TCO_RLD register wasn't previously written to prevent timeout. This patch adds support to TCO watchdog logic and few other features like mapping NMIs to SMIs (NMI2SMI_EN bit), system intruder detection, etc. are not implemented yet.

These commands are handled entirely by QEMU. Do not raise an SMI when they happen, because Windows (at least 2008r2) expects these commands to work and (depending on the value of APMC_EN at startup) the firmware might not have installed an SMI handler. When this happens (e.g. the kernel supports SMIs, or you are using TCG, but you have used "-machine smm=off") RIP is moved to 0x38000 where there is no code to execute. Acked-by: Michael S.

2015-04-02hw: Mark devices picking up char backends actively FIXMEMarkus Armbruster
Character devices defined with -serial and -parallel are for board initialization to wire up. Board code examines serial_hds[] and parallel_hds[] to find them, and creates devices with their qdev chardev properties set accordingly. Except a few devices go on a fishing expedition for a suitable backend instead of exposing a chardev property for board code to set: they use serial_hds[] (often via qemu_char_get_next_serial()) or parallel_hds[] in their realize() or init() method to connect to a backend. Picking up backends that way works when the devices are created by board code. But it's inappropriate for -device or device_add. Not only is it inconsistent with how the other characrer device models work (they connect to a backend explicitly identified by a "chardev" property), it breaks when the backend has been picked up by the board or a previous -device / device_add already. Example: $ qemu-system-ppc64 -M bamboo -S -device i82378 -device pc87312 -device pc87312 qemu-system-ppc64: -device pc87312: Property 'isa-parallel.chardev' can't take value 'parallel0', it's in use Mark them with suitable FIXME comments.

Except a few devices go on a fishing expedition for a suitable backend instead of exposing a drive property for board code to set: they call driver_get() or drive_get_next() in their realize() or init() method to implicitly connect to the "next" backend with a certain interface type. Picking up backends that way works when the devices are created by board code. But it's inappropriate for -device or device_add. Not only is this inconsistent with how the other block device models work (they connect to a backend explicitly identified by a "drive" property), it breaks when the "next" backend has been picked up by the board already. Example: $ qemu-system-arm -S -M connex -pflash flash.img -device ssi-sd Aborted (core dumped) Mark them with suitable FIXME comments.

2015-02-26acpi, ich9: Add unplug cb for ich9.Tang Chen
Memory and CPU hot unplug are both asynchronous procedures. When the unplug operation happens, unplug request cb is called first. And when guest OS finished handling unplug, unplug cb will be called to do the real removal of device. This patch adds hotunplug cb to ich9, which memory and CPU hot unplug will use it.

superio_ioport_readb can read the 256th element of the array. Coverity reports an out-of-bounds write in superio_ioport_writeb, but it does not show the corresponding out-of-bounds read because it cannot prove that it can happen.

2014-10-20hw: Convert from BlockDriverState to BlockBackend, mostlyMarkus Armbruster
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. The next two commits take care of the latter two. Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Max Reitz <mreitz@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2014-10-20block: Eliminate DriveInfo member bdrv, use blk_by_legacy_dinfo()Markus Armbruster
The patch is big, but all it really does is replacing dinfo->bdrv by blk_bs(blk_by_legacy_dinfo(dinfo)) The replacement is repetitive, but the conversion of device models to BlockBackend is imminent, and will shorten it to just blk_legacy_dinfo(dinfo). Line wrapping muddies the waters a bit. I also omit tests whether dinfo->bdrv is null, because it never is.
