2010-07-26vmstate: add subsections codeJuan Quintela2-1/+91
This commit adds subsections for each device section. Subsections is the way to handle information that don't need to be sent to de destination of a migration because its values are not needed. It is the way to handle optional information. Notice that only the source can decide if the information is optional or not. The destination needs to understand all subsections that it receives to have a sucessful load. Signed-off-by: Juan Quintela <quintela@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2010-07-24mips: Correct MIPS interrupt glue logic for icountEdgar E. Iglesias3-31/+6
When hw interrupt pending bits in CP0_Cause are set, the CPU should see the hw interrupt line as active.

2010-07-22scsi: Dequeue requests before invoking completion callbackJan Kiszka2-1/+12
The request completion callback of the LSI controller may start the next request that can use the same tag as the completed one. As the latter is still enqueued at that point, scsi_send_command will complain about the tag reuse and cancel the completed request. That will cause a double free later on when the completion path cleans up as well. Fix this by dequeuing the request before invoking the callback.

2010-07-22e1000: Fix wrong microwire EEPROM state initializationIzumi Tsutsui1-9/+8
This change fixes initialization of e1000's microwire EEPROM internal state values so that qemu's e1000 emulation works on NetBSD, which doesn't use Intel's em driver but has its own wm driver for the Intel i8254x Gigabit Ethernet. Previously set_eecd() function in e1000.c clears EEPROM internal state values on SK rising edge during CS==L, but according to FM93C06 EEPROM (which is MicroWire compatible) data sheet, EEPROM internal status should be cleared on CS rise edge regardless of SK input: "... a rising edge on this (CS) signal is required to reset the internal state-machine to accept a new cycle .." and nothing should be changed during CS (chip select) is inactive. Intel's em driver seems to explicitly raise SK output after CS is negated in em_standby_eeprom() so many other OSes that use Intel's driver don't have this problem even on the previous e1000.c implementation, but I can't find any articles that say the MICROWIRE or EEPROM spec requires such sequence, and actually hardware works fine without it (i.e. real i82540EM has been working on NetBSD). This fix also changes initialization to clear each state value in struct eecd_state individually rather than using memset() against the whole structre. The old_eecd member stores the last SK and CS signal levels and it should be preserved even after reset of internal EEPROM state to detect next signal edges for proper EEPROM emulation.

2010-07-22Rework debug exception processing for gdb useJan Kiszka2-12/+16
Guest debugging is currently broken under CONFIG_IOTHREAD. The reason is inconsistent or even lacking signaling the debug events from the source VCPU to the main loop and the gdbstub. This patch addresses the issue by pushing this signaling into a CPUDebugExcpHandler: cpu_debug_handler is registered as first handler, thus will be executed last after potential breakpoint emulation handlers. It sets informs the gdbstub about the debug event source, requests a debug exit of the main loop and stops the current VCPU. This mechanism works both for TCG and KVM, with and without IO-thread.

When checking for I/O events in the tcg CPU loop, make sure that we call qemu_wait_io_event_common for all CPUs, not only the current one. Otherwise pause_all_vcpus may lock up or run_on_cpu requests may starve. Rename qemu_wait_io_event to qemu_tcg_wait_io_event at this chance and purge its argument list as it has no use for it.

2010-07-22Fix cpu_exit for tcp_cpu_execJan Kiszka2-3/+3
If a cpu_exit request is pending, ensure that we leave the CPU loop quickly. For this purpose, keep the global exit_request pending until we are about to leave tcg_cpu_exec. Also, immediately break out of the SMP loop if the request is set, do not run till the end of the chain. This preserves the VCPU scheduling order in SMP mode.

2010-07-22Fix cpu_unlink_tb raceJan Kiszka1-3/+4
If a signal hit after the env->exit_request check but before cpu_exec updated env->current_tb, cpu_unlink_tb called from the signal hander will not unlink the current TB. This may leave us stuck in a guest loop if no further unlink is invoked. Fix this by reordering current_tb update and exit_request check, additionally enforcing the correct order via a compiler barrier.
