2012-04-12kvm: set gsi_bits and max_gsi correctlyJason Baron
The current kvm_init_irq_routing() doesn't set up the used_gsi_bitmap correctly, and as a consequence pins max_gsi to 32 when it really should be 1024. I ran into this limitation while testing pci passthrough, where I consistently got an -ENOSPC return from kvm_get_irq_route_gsi() called from assigned_dev_update_msix_mmio().

2012-04-12kvm: add flightrecorder scriptStefan Hajnoczi
The kvm kernel module includes a number of trace events which can be useful when debugging system behavior. Even on production systems these trace events can be used to observe guest behavior and identify the source of problems. The kvm_flightrecorder script is a command-line wrapper for the /sys/kernel/debug/tracing interface. Kernel symbols do not need to be installed. This script captures a fixed-size buffer of KVM trace events. Recent events overwrite the oldest events when the buffer size is exceeded and it is possible to leave KVM tracing enabled for any period of time with just a fixed-size buffer. If the buffer is large enough this script is a useful tool for collecting detailed information after an issue occurs with a guest. Hence the name "flight recorder". The script can also be used in 'tail' mode to simply view KVM trace events as they occur. This is handy for development and to ensure that the guest is indeed running.

2012-04-11rtl8139: do not assume TxStatus[] and TxAddr[] are adjacentStefan Hajnoczi
Commit afe0a595356192d5f79703cf6462fcc112df007c ("rtl8139: support byte read to TxStatus registers") reused rtl8139_TxStatus_read() for reading TxAddr registers. It relies on the fact that TxStatus[] and TxAddr[] are adjacent. This causes a gcc warning because the compiler can detect that array access is out-of-bounds: hw/rtl8139.c:2501:27: error: array subscript is above array bounds [-Werror=array-bounds] This patch refactors the function so that we don't rely on out-of-bounds accesses.

2012-04-09qdev: qdev_unplug(): use error_set()Luiz Capitulino
It currently uses qerror_report(), but next commit will convert the drive_del command to the QAPI and this requires using error_set(). One particularity of qerror_report() is that it knows when it's running on monitor context or command-line context and prints the error message accordingly. error_set() doesn't do this, so we have to be careful not to drop error messages. qdev_unplug() has three kinds of usages: 1. It's called when hot adding a device fails, to undo anything that has been done before hitting the error 2. It's called by function monitor functions like device_del(), to unplug a device 3. It's used by xen_platform.c in a way that doesn't _seem_ to be in monitor context Only item 2 can print an error message to the user, this commit maintains that.

2012-04-07w64: Fix data type of tb_next and other variables used for host addressesStefan Weil
QEMU host addresses must use uintptr_t to be portable for hosts with an unusual size of long (w64). tb_jmp_offset is an uint16_t value, therefore the local variable offset in function tb_set_jmp_target was changed from unsigned long to uint16_t. The type cast to long in function tb_add_jump now also uses uintptr_t. For the bit operation used here, the signedness of the type cast does not matter. Some remaining unsigned long values are either only used for ARM assembler code or will be fixed in a later patch for PPC. v2: Fix signature of tb_find_pc in exec.c, too (hint from Blue Swirl, thanks). There remain lots of other long / unsigned long in exec.c which must be replaced by uintptr_t. This will be done in a separate patch. Here only one of these type casts is fixed. v3: Also fix signature of page_unprotect. Signed-off-by: Stefan Weil <sw@weilnetz.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2012-04-07main-loop: interrupt wait when data arrives on a socketPaolo Bonzini
Right now, the main loop is not interrupted when data arrives on a socket. To fix this, register each socket to interrupt the main loop with WSAEventSelect. This does not replace select, it only communicates a change in socket state that requires a select call. Since the interrupt fires only once per recv call, or only once after a send call returns EWOULDBLOCK we can activate it on all events unconditionally. If QEMU is momentarily uninterested on some condition, the main loop will not busy wait. Instead, it may get one extra wakeup, but then it will ignore the condition until progress occurs and/or qemu_set_fd_handler is called to set a callback. At this point the condition will be tested via select and the callback will be invoked even if it is still disabled on the event.
