2012-08-14kvm: i8254: Finish time conversion fixJan Kiszka1-4/+10
0cdd3d1444 fixed reading back the counter load time from the kernel while assuming the kernel would always update its load time on writing the state. That is only true for channel 1, and so pit_get_channel_info returned wrong output pin states for high counter values. Fix this by applying the offset also on kvm_pit_put. Now we also need to update the offset when we write the state while the VM is stopped as it keeps on changing in that state.

2012-08-14kvm: i8254: Cache kernel clock offset in KVMPITStateJan Kiszka1-14/+24
To prepare the final fix for clock calibration issues with the in-kernel PIT, we want to cache the offset between vmclock and the clock used by the in-kernel PIT. So far, we only need to update it when the VM state changes between running and stopped because we only read the in-kernel PIT state while the VM is running.

2012-08-13qmp: add SUSPEND_DISK eventLuiz Capitulino1-0/+2
Emitted when the guest makes a request to enter S4 state. There are three possible ways of having this event, as described here: http://lists.gnu.org/archive/html/qemu-devel/2012-07/msg02307.html I've decided to add a new event and make it indepedent of SHUTDOWN. This means that the SHUTDOWN event will eventually follow the SUSPEND_DISK event. I've choosen this way because of two reasons: 1. Having an indepedent event makes it possible to query for its existence by using query-events 2. In the future, we may allow the user to change what QEMU should do as a result of the guest entering S4. So it's a good idea to keep both events separated Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>

Fix an incorrect default value for the num-irqs property (we were attempting to override it from the default set by the parent class but not succeeding, which meant that the lm3s6965evb model would assert on startup attempting to wire up nonexistent irq lines). Instead of trying to override the parent's Property array, we define an instance_init function which runs after default setup but before user property setting and can just fix up the default value in the gic_state struct.

2012-08-10ahci: Fix sglist memleak in ahci_dma_rw_buf()Jason Baron1-0/+3
I noticed that in hw/ide/ahci:ahci_dma_rw_buf() we do not free the sglist. Thus, I've added a call to qemu_sglist_destroy() to fix this memory leak. In addition, I've adeed a call in qemu_sglist_destroy() to 0 all of the sglist fields, in case there is some other codepath that tries to free the sglist.

2012-08-10ahci: Fix ahci cdrom read corruptions for reads > 128kJason Baron2-7/+35
While testing q35, which has its cdrom attached to the ahci controller, I found that the Fedora 17 install would panic on boot. The panic occurs while squashfs is trying to read from the cdrom. The errors are: [ 8.622711] SQUASHFS error: xz_dec_run error, data probably corrupt [ 8.625180] SQUASHFS error: squashfs_read_data failed to read block 0x20be48a I was also able to produce corrupt data reads using an installed piix based qemu machine, using 'dd'. I found that the corruptions were only occuring when then read size was greater than 128k. For example, the following command results in corrupted reads: dd if=/dev/sr0 of=/tmp/blah bs=256k iflag=direct The > 128k size reads exercise a different code path than 128k and below. In ide_atapi_cmd_read_dma_cb() s->io_buffer_size is capped at 128k. Thus, ide_atapi_cmd_read_dma_cb() is called a second time when the read is > 128k. However, ahci_dma_rw_buf() restart the read from offset 0, instead of at 128k. Thus, resulting in a corrupted read. To fix this, I've introduced 'io_buffer_offset' field in IDEState to keep track of the offset. I've also modified ahci_populate_sglist() to take a new 3rd offset argument, so that the sglist is property initialized. I've tested this patch using 'dd' testing, and Fedora 17 now correctly boots and installs on q35 with the cdrom ahci controller.
