2011-03-07tcg: Add support for debugging leakage of temporariesPeter Maydell2-0/+49
Add support (if CONFIG_DEBUG_TCG is defined) for debugging leakage of temporary variables. Generally any temporaries created by a target while it is translating an instruction should be freed by the end of that instruction; otherwise carefully crafted guest code could cause TCG to run out of temporaries and assert. By calling tcg_check_temp_count() after each instruction we can check that we are not leaking temporaries in this way.

2011-03-06target-arm: Set carry flag correctly for Thumb2 ORNSPeter Maydell1-2/+1
The code for Thumb2 ORNS (or negated and set flags) was trashing a TCG input register which was needed later for use in calculating flags, with the effect that the carry flag was always set with the wrong sense. Fix this by using the TCG orc op instead of separate not and or ops. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2011-03-06target-arm: Handle VMOV between two core and VFP single regsPeter Maydell1-5/+5
Fix two bugs in the translation of the instructions VMOV sa,sb,rx,ry and VMOV rx,ry,sa,sb (which copy between a pair of ARM core registers and a pair of VFP single precision registers): * An incorrect condition meant these instruction patterns were being treated as load/store multiple, which resulted in the generation of bad code and a runtime segfault * The order of the core register pair was reversed so the values would go to the wrong registers Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2011-03-06target-arm: Don't decode old cp15 WFI instructions on v7 coresPeter Maydell1-5/+30
In v7 of the ARM architecture, WFI (wait for interrupt) is a first-class instruction, but in previous versions this functionality was provided via a cp15 coprocessor register. Add correct feature checks to the decoding of the cp15 WFI instructions so that they behave correctly for newer cores. In particular, the old 0,c7,c8,2 encoding used on ARM940 has been reused for VA-to-PA translation in v6 and v7.

2011-03-06simpletrace: Make simpletrace.py a Python moduleStefan Hajnoczi1-33/+90
The simpletrace.py script pretty-prints a binary trace file. Most of the code can be reused by trace file analysis scripts, so turn it into a module. Here is an example script that uses the new simpletrace module: #!/usr/bin/env python # Print virtqueue elements that were never returned to the guest. import simpletrace class VirtqueueRequestTracker(simpletrace.Analyzer): def __init__(self): self.elems = set() def virtqueue_pop(self, vq, elem, in_num, out_num): self.elems.add(elem) def virtqueue_fill(self, vq, elem, length, idx): self.elems.remove(elem) def end(self): for elem in self.elems: print hex(elem) simpletrace.run(VirtqueueRequestTracker()) The simpletrace API is based around the Analyzer class. Users implement an analyzer subclass and add methods for trace events they want to process. A catchall() method is invoked for trace events which do not have dedicated methods. Finally, there are also begin() and end() methods like in sed that can be used to perform setup or print statistics at the end. A binary trace file is processed either with: simpletrace.run(analyzer) # uses command-line args or with: simpletrace.process('path/to/trace-events', 'path/to/trace-file', analyzer) Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-03-06linux-user: Fix large seeks by 32 bit guest on 64 bit hostPeter Maydell1-6/+10
When emulating a 32 bit Linux user-mode program on a 64 bit target we implement the llseek syscall in terms of lseek. Correct a bug which meant we were silently casting the result of host lseek() to a 32 bit integer as it passed through get_errno() and thus throwing away the top half. We also don't try to store the result back to userspace unless the seek succeeded; this matches the kernel behaviour. Thanks to Eoghan Sherry for identifying the problem and suggesting a solution.

2011-03-05net: fix qemu_can_send_packet logicVincent Palatin1-3/+3
If any of the clients is not ready to receive (ie it has a can_receive callback and can_receive() returns false), we don't want to start sending, else this client may miss/discard the packet. I got this behaviour with the following setup : the emulated machine is using an USB-ethernet adapter, it is connected to the network using SLIRP and I'm dumping the traffic in a .pcap file. As per the following command line : -net nic,model=usb,vlan=1 -net user,vlan=1 -net dump,vlan=1,file=/tmp/pkt.pcap Every time that two packets are coming in a row from the host, the usb-net code will receive the first one, then returns 0 to can_receive call since it has a 1 packet long queue. But as the dump code is always ready to receive, qemu_can_send_packet will return true and the next packet will discard the previous one in the usb-net code.

2011-03-03virtio-net: Fix lduw_p() pointer argument of wrong sizeStefan Hajnoczi1-2/+2
A pointer to a size_t variable was passed as the void * pointer to lduw_p() in virtio_net_receive(). Instead of acting on the 16-bit value this caused failure on big-endian hosts. Avoid this issue in the future by using stw_p() instead. In general we should use ld*_p() for loading from target memory and st*_p() for storing to target memory anyway, not the other way around. Also tighten up a correct use of lduw_p() when stw_p() should be used instead in virtio_net_get_config().

2011-03-03target-sh4: move intr_at_halt out of cpu_halted()Aurelien Jarno4-4/+4
All targets except SH4 have the same cpu_halted() routine, and it has only one caller. It is therefore a good candidate for inlining. The difference is the handling of the intr_at_halt, which is necessary to ignore SR.BL when sleeping. Move intr_at_halt handling out of it, by setting this variable while executing the sleep instruction, and clearing it when the CPU has been woken-up by an interrupt, whatever the state of SR.BL. Also rename this variable in_sleep. Cc: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
