2019-02-01uuid: Make qemu_uuid_bswap() take and return a QemuUUIDPeter Maydell1-4/+2
Currently qemu_uuid_bswap() takes a pointer to the QemuUUID to be byte-swapped. This means it can't be used when the UUID to be swapped is in a packed member of a struct. It's also out of line with the general bswap*() functions we provide in bswap.h, which take the value to be swapped and return it. Make qemu_uuid_bswap() take a QemuUUID and return the swapped version. This fixes some clang warnings about taking the address of a packed struct member in block/vdi.c.

2019-02-01hw/display/milkymist-tmu2: Move inlined code from header to sourcePhilippe Mathieu-Daudé3-63/+50
Move the complexity of milkymist_tmu2_create() into the source file. Doing so we avoid to include the X11/OpenGL headers in all LM32 devices, and we also avoid the duplicate declaration of glx_fbconfig_attr[] (it is already declared in hw/display/milkymist-tmu2.c). Since TYPE_MILKYMIST_TMU2 is now accessible, use it.

2019-01-30usb: assign unique serial numbers to hid devicesGerd Hoffmann2-11/+18
Windows guests have trouble dealing with usb devices having identical serial numbers. So, assign unique serial numbers to usb hid devices. All other usb devices have this already. In the past the fixed serial number has been used to indicate working remote setup to linux guests. Here is a bit of history: * First there was nothing. * Then I added a rule to udev checking for serial == 42. (this is in rhel-6). * Then systemd + udev merged. * Then I changed the rule to check for serial != 1 instead, so we can use any serial but "1" which is the one the old broken devices had (this is in rhel-7). March 2014 in upstream systemd. * Then all usb power management rules where dropped from systemd (June 2015). Which I figured today (Sept 2018), after wondering that the rules are gone in fedora 28. So, three years ago the serial number check was dropped upstream, yet I hav't seen a single report about autosuspend issues (or cpu usage for usb emulation going up, which is the typical symtom). So I figured I can stop worring that changing the serial number will break things and just do it. And even if it turns out autosuspend is still an issue: I think meanwhile we can really stop worrying about guests running in old qemu versions with broken usb suspend (fixed in 0.13 !). If needed we can enable autosuspend unconditionally in guests. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Message-id: 20190110125108.22834-1-kraxel@redhat.com

2019-01-29qom/cpu: Add cluster_index to CPUStatePeter Maydell1-0/+46
For TCG we want to distinguish which cluster a CPU is in, and we need to do it quickly. Cache the cluster index in the CPUState struct, by having the cluster object set cpu->cluster_index for each CPU child when it is realized. This means that board/SoC code must add all CPUs to the cluster before realizing the cluster object. Regrettably QOM provides no way to prevent adding children to a realized object and no way for the parent to be notified when a new child is added to it, so we don't have any way to enforce/assert this constraint; all we can do is document it in a comment. We can at least put in a check that the cluster contains at least one CPU, which should catch the typical cases of "realized cluster too early" or "forgot to parent the CPUs into it". The restriction on how many clusters can exist in the system is imposed by TCG code which will be added in a subsequent commit, but the check to enforce it in cluster.c fits better in this one.

Currently the cluster implementation doesn't have any constraints on the ordering of realizing the TYPE_CPU_CLUSTER and populating it with child objects. We want to impose a constraint that realize must happen only after all the child objects are added, so move the realize of rpu_cluster. (The apu_cluster is already realized after child population.)

2019-01-29aspeed/smc: snoop SPI transfers to fake dummy cyclesCédric Le Goater1-3/+112
The m25p80 models dummy cycles using byte transfers. This works well when the transfers are initiated by the QEMU model of a SPI controller but when these are initiated by the OS, it breaks emulation. Snoop the SPI transfer to catch commands requiring dummy cycles and replace them with byte transfers compatible with the m25p80 model.

2019-01-24trace: forbid use of %m in trace event format stringsDaniel P. Berrangé2-2/+2
The '%m' format instructs glibc's printf()/syslog() implementation to insert the contents of strerror(errno). Since this is a glibc extension it should generally be avoided in QEMU due to need for portability to a variety of platforms. Even though vfio is Linux-only code that could otherwise use "%m", it must still be avoided in trace-events files because several of the backends do not use the format string and so this error information is invisible to them. The errno string value should be given as an explicit trace argument instead, making it accessible to all backends. This also allows it to work correctly with future patches that use the format string with systemtap's simple printf code. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P.
