Popular glibc based distributions[1] require minimum 2.6.32 as kernel version. For some targets 2.6.18 would be enough, but dropping so low would mean some suboptimal system calls could get used.

2014-03-10ui/vnc: optimize dirty bitmap trackingPeter Lieven2-71/+88
vnc_update_client currently scans the dirty bitmap of each client bitwise which is a very costly operation if only few bits are dirty. vnc_refresh_server_surface does almost the same. this patch optimizes both by utilizing the heavily optimized function find_next_bit to find the offset of the next dirty bit in the dirty bitmaps. The following artifical test (just the bitmap operation part) running vnc_update_client 65536 times on a 2560x2048 surface illustrates the performance difference: All bits clean - vnc_update_client_new: 0.07 secs vnc_update_client_old: 10.98 secs All bits dirty - vnc_update_client_new: 11.26 secs vnc_update_client_old: 20.19 secs Few bits dirty - vnc_update_client_new: 0.08 secs vnc_update_client_old: 10.98 secs The case for all bits dirty is still rather slow, this is due to the implementation of find_and_clear_dirty_height.

2014-03-10vnc: Fix qemu crashed when vnc client disconnect suddenlyGonglei (Arei)1-0/+5
Hi, When I use RealVNC viewer client (http://www.realvnc.com/) to connect vnc server, the client disconnect suddenly, and I click reconnect button immediately, then the Qemu crashed. In the function vnc_worker_thread_loop, will call vnc_async_encoding_start to set the local vs->output buffer by global queue's buffer. Then send rectangles to the vnc client call function vnc_send_framebuffer_update. Finally, Under normal circumstances, call vnc_async_encoding_end to set the global queue'buffer by the local vs->output conversely. When the vnc client disconnect, the job->vs->csock will be set to -1. And the current prcoess logic will goto disconnected partion without call function vnc_async_encoding_end. But, the function vnc_send_framebuffer_update will call buffer_reserve, which maybe call g_realloc reset the local vs's buffer, meaning the global queue's buffer is modified also. If anyone use the original global queue's buffer memory will cause corruption and then crash qemu. This patch assure the function vnc_async_encoding_end being called even though the vnc client disconnect suddenly.

VncTight member uint8_t quality is either (uint8_t)-1 for lossless or less than 10 for lossy. tight_detect_smooth_image() first promotes it to int, then compares with -1. Always unequal, so we always execute the lossy code. Reads beyond tight_conf[] and returns crap when quality is actually lossless. Compare to (uint8_t)-1 instead, like we do elsewhere.

2014-03-09qemu: x86: ignore ioapic polarityGabriel L. Somlo1-3/+0
Both QEMU and KVM have already accumulated a significant number of optimizations based on the hard-coded assumption that ioapic polarity will always use the ActiveHigh convention, where the logical and physical states of level-triggered irq lines always match (i.e., active(asserted) == high == 1, inactive == low == 0). QEMU guests are expected to follow directions given via ACPI and configure the ioapic with polarity 0 (ActiveHigh). However, even when misbehaving guests (e.g. OS X <= 10.9) set the ioapic polarity to 1 (ActiveLow), QEMU will still use the ActiveHigh signaling convention when interfacing with the emulated ioapic. This patch modifies the emulated ioapic to completely ignore polarity as set by the guest OS, enabling misbehaving guests to work alongside those which comply with the ActiveHigh polarity specified by QEMU's ACPI tables.

2014-03-09pam: partly fix write-only modeHervé Poussineau1-1/+1
In write-only mode, writes are forwarded to RAM, while reads should not be handled (ie should return 0xff). Assume that in this mode, no read access is ever done, as they shouldn't give any sensible result. So, in write-only mode, alias PAM region to RAM, instead of PCI memory (which can even be mapped to some device!) This fixes Award BIOS, which use this mode to shadow system BIOS and video BIOS.

2014-03-09memory_region_present: return false if address is not found in child ↵Igor Mammedov2-4/+4
MemoryRegion Windows XP shows COM2 port as non functional in "Device Manager" although no COM2 port backing device is present in QEMU. This regression is really due to 3bb28b7208b349e7a1b326e3c6ef9efac1d462bf? memory: Provide separate handling of unassigned io ports accesses That is caused by the fact that QEMU reports to OSPM that device is present by setting 5th bit in PII4XPM.pci_conf[0x67] register when COM2 doesn't exist. It happens due to memory_region_present(io_as, 0x2f8) returning false positive since 0x2f8 address eventually translates into catchall io_as address space. Fix memory_region_present(parent, addr) by returning true only if addr maps into a MemoryRegion within parent (excluding parent itself), to match its doc comment. While at it fix copy/paste error in memory_region_present() doc comment. Note: this is a temporary hack: we really need better handling for unassigned regions, we should avoid fallback regions since they are bad for performance (breaking radix tree assumption that the data structure is sparsely populated); for memory we need to fix this to implement PCI master abort properly, anyway.

2014-03-09acpi-build: append description for non-hotplugMichael S. Tsirkin7-264/+500
As reported in http://article.gmane.org/gmane.comp.emulators.qemu/253987 Mac OSX actually requires describing all occupied slots in ACPI - even if hotplug isn't enabled. I didn't expect this so I dropped description of all non hotpluggable slots from ACPI. As a result: before commit 99fd437dee468609de8218f0eb3b16621fb6a9c9 (enable hotplug for pci bridges), PCI cards show up in the "device tree" of OS X (System Information). E.g., on MountainLion users have: Hardware -> PCI Cards: Card Type Driver Installed Slot *ethernet Ethernet Controller Yes PCI Slot 2 pci8086,2934 USB UHC Yes PCI Slot 29 ethernet: Type: Ethernet Controller Driver Installed: Yes MSI: No Bus: PCI Slot PCI Slot 2 Vendor ID: 0x8086 Device ID: 0x100e Subsystem Vendor ID: 0x1af4 Subsystem ID: 0x1100 Revision ID: 0x0003 Hardware -> Ethernet Cards ethernet: Type: Ethernet Controller Bus: PCI Slot PCI Slot 2 Vendor ID: 0x8086 Device ID: 0x100e Subsystem Vendor ID: 0x1af4 Subsystem ID: 0x1100 Revision ID: 0x0003 BSD name: en0 Kext name: AppleIntel8254XEthernet.kext Location: /System/Library/Extensions/...
