2009-06-17Call piix4_reset() on system reset.Blue Swirl
Also zero pci_irq_levels on reset to avoid stuck irq after reset. Based on 15a1956af94e36105494f782a752698103addf63 by Gleb Natapov. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2009-06-17Revert "Update irqs on reset and device load"Blue Swirl
This reverts commit 3dcd219f09d6c1817bf9a132899e6b925f7a0914. It is incorrect to call qemu_irq functions (or any other functions that access other device state) during savevm/loadvm. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2009-06-16Fix vga_screen_dump_blank() PPM generationEduardo Habkost
vga_screen_dump_blank() was not generating a valid PPM file: the width of the image made no sense (why it was multiplied by sizeof(uint32_t)?), and there was only one sample per pixel, instead of three.

2009-06-16Prevent CD-ROM media eject while device is lockedMark McLoughlin
Section 10.8.25 ("START/STOP UNIT Command") of SFF-8020i states that if the device is locked we should refuse to eject if the device is locked. ASC_MEDIA_REMOVAL_PREVENTED is the appropriate return in this case. In order to stop itself from ejecting the media it is running from, Fedora's installer (anaconda) requires the CDROMEJECT ioctl() to fail if the drive has been previously locked.

2009-06-13Don't use cpu_index as apic_id.Gleb Natapov
(patch is on top of "Apic creation should not depend on pci" series) Currently cpu_index is used as cpu apic id on x86. This is incorrect since apic ids not have to be continuous (they can also encode cpu hierarchy information). This patch uses cpuid_apic_id for initial apic id value. For now cpuid_apic_id is set to be equal to cpu_index so behaviour is fully backward compatible, but it allows us to add qemu option to provide other values for cpu apic id.

2009-06-13Fix SDL include path.Stefan Weil
SDL header files can be included in two different ways: * like this: #include <SDL/SDL.h> * like this: #include <SDL.h> The 1st alternative is simple and works in many cases. The 2nd alternative needs sdl-config to get the correct compiler flags. It is the recommended way to write SDL includes and standard for QEMU. The patch fixes two non-standard SDL includes.

2009-06-09virtio-net: Increase filter and control limitsAlex Williamson
Increase the size of the perfect filter table and control queue depth. This should give us more headroom in the MAC filter and is known to be needed by at least one guest user. Increasing the control queue depth allows a guest to feed several commands back to back if they so desire rather than using the send and wait approach Linux uses.

2009-06-09virtio-net: Add new RX filter controlsAlex Williamson
Add a few new RX modes to better control the receive_filter. These are all fairly obvious features that hardware could provide. Signed-off-by: Alex Williamson <alex.williamson@hp.com> Signed-off-by: Mark McLoughlin <markmc@redhat.com>
2009-06-09virtio-net: MAC filter optimizationAlex Williamson
The MAC filter table is received from the guest as two separate buffers, one with unicast entries, the other with multicast entries. If we track the index dividing the two sets, we can avoid searching the part of the table with the wrong type of entries. We could store this index as part of the save image, but its trivially easy to discover it on load.

2009-06-09virtio-net: Fix MAC filter overflow handlingAlex Williamson
Overloading the promisc and allmulti flags for indicating filter table overflow makes it difficult to track the actual requested operating mode. Split these out into separate flags. Signed-off-by: Alex Williamson <alex.williamson@hp.com> Signed-off-by: Mark McLoughlin <markmc@redhat.com>
2009-06-09virtio-net: reorganize receive_filter()Alex Williamson
Reorganize receive_filter to better handle the split between unicast and multicast filtering. This allows us to skip the broadcast check on unicast packets and leads to more opportunities for optimization.

2009-06-09virtio-net: Use a byte to store RX mode flagsAlex Williamson
