2018-05-06RISC-V: Remove unused class definitionsMichael Clark4-22/+0
Removes a whole lot of unnecessary boilerplate code. Machines don't need to be objects. The expansion of the SOC object model for the RISC-V machines will happen in the future as SiFive plans to add their FE310 and FU540 SOCs to QEMU. However, it seems that this present boilerplate is complete unnecessary.

2018-05-04qobject: Replace qobject_incref/QINCREF qobject_decref/QDECREFMarc-André Lureau2-23/+19
Now that we can safely call QOBJECT() on QObject * as well as its subtypes, we can have macros qobject_ref() / qobject_unref() that work everywhere instead of having to use QINCREF() / QDECREF() for QObject and qobject_incref() / qobject_decref() for its subtypes. The replacement is mechanical, except I broke a long line, and added a cast in monitor_qmp_cleanup_req_queue_locked(). Unlike qobject_decref(), qobject_unref() doesn't accept void *. Note that the new macros evaluate their argument exactly once, thus no need to shout them.

2018-05-04qobject: use a QObjectBase_ structMarc-André Lureau7-17/+26
By moving the base fields to a QObjectBase_, QObject can be a type which also has a 'base' field. This allows writing a generic QOBJECT() macro that will work with any QObject type, including QObject itself. The container_of() macro ensures that the object to cast has a QObjectBase_ base field, giving some type safety guarantees. QObject must have no members but QObjectBase_ base, or else QOBJECT() breaks. QObjectBase_ is not a typedef and uses a trailing underscore to make it obvious it is not for normal use and to avoid potential abuse.

2018-05-03linux-user: remove useless padding in flock64 structureLaurent Vivier1-1/+1
Since commit 8efb2ed5ec ("linux-user: Correct signedness of target_flock l_start and l_len fields"), flock64 structure uses abi_llong for l_start and l_len in place of "unsigned long long" this should force them to be aligned accordingly to the target rules. So we can remove the padding field and the QEMU_PACKED attribute. I have compared the result of the following program before and after the change: cat -> flock64_dump <<EOF p/d sizeof(struct target_flock64) p/d &((struct target_flock64 *)0)->l_type p/d &((struct target_flock64 *)0)->l_whence p/d &((struct target_flock64 *)0)->l_start p/d &((struct target_flock64 *)0)->l_len p/d &((struct target_flock64 *)0)->l_pid quit EOF for file in build/all/*-linux-user/qemu-* ; do echo $file gdb -batch -nx -x flock64_dump $file 2> /dev/null done The sizeof() changes because we remove the QEMU_PACKED. The new size is 32 (except for i386 and m68k) and this is the real size of "struct flock64" on the target architecture. The following architectures differ: aarch64_be, aarch64, alpha, armeb, arm, cris, hppa, nios2, or1k, riscv32, riscv64, s390x. For a subset of these architectures, I have checked with the following program the new structure is the correct one: #include <stdio.h> #define __USE_LARGEFILE64 #include <fcntl.h> int main(void) { printf("struct flock64 %d\n", sizeof(struct flock64)); printf("l_type %d\n", &((struct flock64 *)0)->l_type); printf("l_whence %d\n", &((struct flock64 *)0)->l_whence); printf("l_start %d\n", &((struct flock64 *)0)->l_start); printf("l_len %d\n", &((struct flock64 *)0)->l_len); printf("l_pid %d\n", &((struct flock64 *)0)->l_pid); } [I have checked aarch64, alpha, hppa, s390x] For ARM, the target_flock64 becomes the EABI definition, so we need to define the OABI one in place of the EABI one and use it when it is needed. I have also fixed the alignment value for sh4 (to align llong on 4 bytes) (see c2e3dee6e0 "linux-user: Define target alignment size") [We should check alignment properties for cris, nios2 and or1k] Signed-off-by: Laurent Vivier <laurent@vivier.eu> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-Id: <20180502215730.28162-1-laurent@vivier.eu>

2018-04-30hw/s390x: Allow to configure the consoles with the "-serial" parameterThomas Huth2-1/+2
The consoles ("sclpconsole" and "sclplmconsole") can only be configured with "-device" and "-chardev" so far. Other machines use the convenience option "-serial" to configure the default consoles, even for virtual consoles like spapr-vty on the pseries machine. So let's support this option on s390x, too. This way we can easily enable the serial console here again with "-nodefaults", for example: qemu-system-s390x -no-shutdown -nographic -nodefaults -serial mon:stdio ... which is way shorter than typing: qemu-system-s390x -no-shutdown -nographic -nodefaults \ -chardev stdio,id=c1,mux=on -device sclpconsole,chardev=c1 \ -mon chardev=c1 The -serial parameter can also be used if you only want to see the QEMU monitor on stdio without using -nodefaults, but not the console output. That's something that is pretty impossible with the current code today: qemu-system-s390x -no-shutdown -nographic -serial none While we're at it, this patch also maps the second -serial option to the "sclplmconsole", so that there is now an easy way to configure this second console on s390x, too, for example: qemu-system-s390x -no-shutdown -nographic -serial null -serial mon:stdio Additionally, the new code is also smaller than the old one and we have less s390x-specific code in vl.c :-) I've also checked that migration still works as expected by migrating a guest with console output back and forth between a qemu-system-s390x that has this patch and an instance without this patch.

2018-04-26xen: Use newly added dmops for mapping VGA memoryRoss Lagerwall1-0/+32
Xen unstable (to be in 4.11) has two new dmops, relocate_memory and pin_memory_cacheattr. Use these to set up the VGA memory, replacing the previous calls to libxc. This allows the VGA console to work properly when QEMU is running restricted (-xen-domid-restrict). Wrapper functions are provided to allow QEMU to work with older versions of Xen. Tweak the error handling while making this change: * Report pin_memory_cacheattr errors. * Report errors even when DEBUG_HVM is not set. This is useful for trying to understand why VGA is not working, since otherwise it just fails silently. * Fix the return values when an error occurs. The functions now consistently return -1 and set errno.

xc_interface_open etc. is not going to work if we have dropped privilege, but xendevicemodel_shutdown will if everything is new enough. xendevicemodel_shutdown is only availabe in Xen 4.10 and later, so provide a stub for earlier versions.

2018-04-26xen: move xc_interface compatibility fallback further up the fileIan Jackson1-7/+11
We are going to want to use the dummy xendevicemodel_handle type in new stub functions in the CONFIG_XEN_CTRL_INTERFACE_VERSION < 41000 section. So we need to provide that definition, or (as applicable) include the appropriate header, earlier in the file. (Ideally the newer compatibility layers would be at the bottom of the file, so that they can naturally benefit from the compatibility layers for earlier version. But that's rather too much for this series.) No functional change.

2018-04-26xen: restrict: use xentoolcore_restrict_allIan Jackson1-35/+11
And insist that it works. Drop individual use of xendevicemodel_restrict and xenforeignmemory_restrict. These are not actually effective in this version of qemu, because qemu has a large number of fds open onto various Xen control devices. The restriction arrangements are still not right, because the restriction needs to be done very late - after qemu has opened all of its control fds. xentoolcore_restrict_all and xentoolcore.h are available in Xen 4.10 and later, only. Provide a compatibility stub. And drop the compatibility stubs for the old functions.

2018-04-26superio: Don't use MAX_SERIAL_PORTS for serial port limitPeter Maydell1-1/+3
The superio device has a limit on the number of serial ports it supports which is really only there because it has a fixed-size array serial[]. This limit isn't related particularly to the global MAX_SERIAL_PORTS limit, so use a different #define for it. (In practice the users of superio only ever want 2 serial ports.)

2018-04-26serial-isa: Use MAX_ISA_SERIAL_PORTS instead of MAX_SERIAL_PORTSPeter Maydell1-0/+3
The ISA serial port handling in serial-isa.c imposes a limit of 4 serial ports. This is because we only know of 4 IO port and IRQ settings for them, and is unrelated to the generic MAX_SERIAL_PORTS limit, though they happen to both be set at 4 currently. Use a new MAX_ISA_SERIAL_PORTS wherever that is the correct limit to be checking against.

2018-04-11icount: fix cpu_restore_state_from_tb for non-tb-exit casesPavel Dovgalyuk1-1/+4
In icount mode, instructions that access io memory spaces in the middle of the translation block invoke TB recompilation. After recompilation, such instructions become last in the TB and are allowed to access io memory spaces. When the code includes instruction like i386 'xchg eax, 0xffffd080' which accesses APIC, QEMU goes into an infinite loop of the recompilation. This instruction includes two memory accesses - one read and one write. After the first access, APIC calls cpu_report_tpr_access, which restores the CPU state to get the current eip. But cpu_restore_state_from_tb resets the cpu->can_do_io flag which makes the second memory access invalid. Therefore the second memory access causes a recompilation of the block. Then these operations repeat again and again. This patch moves resetting cpu->can_do_io flag from cpu_restore_state_from_tb to cpu_loop_exit* functions. It also adds a parameter for cpu_restore_state which controls restoring icount. There is no need to restore icount when we only query CPU state without breaking the TB. Restoring it in such cases leads to the incorrect flow of the virtual time. In most cases new parameter is true (icount should be recalculated). But there are two cases in i386 and openrisc when the CPU state is only queried without the need to break the TB. This patch fixes both of these cases.

We would like to have different behavior for passthrough devices depending on the SCSI version they expose. To prepare for that, allow the user of emulated devices to specify the desired SCSI level, and adjust the emulation according to the property value. The next patch will set the level for scsi-block and scsi-generic devices. Based on a patch by Daniel Henrique Barboza <danielhb@linux.vnet.ibm.com>.
