2010-06-01migration: Fix calculation of bytes_transferredPierre Riteau
When a page with all identical bytes is transferred, it is counted as a full page (TARGET_PAGE_SIZE) although only one byte is actually sent. Fix this by changing ram_save_block() to return the number of bytes sent instead of a boolean value. This makes bandwidth estimation, and consequently downtime estimation, more precise.

2010-06-01vnc: tight: add palette encodingCorentin Chary
Add palette tight encoding. Palette encoding will try to count the number of colors for a given rectangle, and if this number is low enough (< 256) it will send the palette + the rectangle with indexed colors.

2010-06-01vnc: add basic tight supportCorentin Chary
Add support for tight encoding [1]. This patch only add support for "basic" tight compression without any filter. [1] http://tigervnc.org/cgi-bin/rfbproto#tight-encoding. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-06-01vnc: return the number of rectanglesCorentin Chary
Some encodings like tight supports tiling (spliting in multiple sub-rectangles). So we needed a way to tell vnc_update_client() how much rectangles are in the buffer. zlib, raw and hextile always send a full rectangle.

2010-06-01vnc: don't clear zlib stream on set_encodingCorentin Chary
On init, values are already NULL, but we shouldn't try to reset them each time a client send a set encoding command because this break everything. For example, libvncclient re-send a set encoding command if the framebuffer is resized. This fix framebuffer resizing for zlib encoding.

2010-06-01vnc: only use a single zlib streamCorentin Chary
According to http://tigervnc.org/cgi-bin/rfbproto#zlib-encoding zlib encoding only uses a single stream. Current implementation defines 4 streams but only uses the first one. Remove them and only use a single stream. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-06-01vnc: really call zlib if we want zlibCorentin Chary

2010-06-01Revert "vnc: set the right prefered encoding"Corentin Chary
This patch was wrong, because the loop was already reversed, so the first encoding was correctly set at the end of the loopp. This reverts commit 14eb8b6829ad9dee7035de729e083844a425f274. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2010-05-31Fix leul_to_cpu on big endian hostsAlexander Graf
Commit 213acd2e introduced leul_to_cpu with a special code path for big endian hosts. Unfortunately that code used preprocessor magic that didn't work. This patch replaces the explicit ##s by glue() which is proven to work reliably, enabling me to compile qemu on ppc again.

2010-05-31arm: fix arm kernel boot for non zero start addrLars Munch
Booting an arm kernel has been broken a while when booting from non zero start address. This is due to the order of events: board init loads the kernel and sets register 15 to the start address and then qemu_system_reset reset the cpu making register 15 zero again. This patch fixes the usage of the register 15 start address trick in combination with arm_load_kernel. Signed-off-by: Lars Munch <lars@segv.dk> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-05-31target-ppc: fix RFI by clearing some bits of MSRThomas Monjalon
Since commit 2ada0ed, "Return From Interrupt" is broken for PPC processors because some interrupt specifics bits of SRR1 are copied to MSR. SRR1 is a save of MSR during interrupt. During RFI, MSR must be restored from SRR1. But some bits of SRR1 are interrupt-specific and are not used for MSR saving. This is the specification (ISA 2.06) at chapter 6.4.3 (Interrupt Processing): "2. Bits 33:36 and 42:47 of SRR1 or HSRR1 are loaded with information specific to the interrupt type. 3. Bits 0:32, 37:41, and 48:63 of SRR1 or HSRR1 are loaded with a copy of the corresponding bits of the MSR." Below is a representation of MSR bits which are not saved: 0:15 16:31 32 33:36 37:41 42:47 48:63 ——— | ——— | — X X X X — — — — — X X X X X X | ———— 0000 0000 | 7 | 8 | 3 | F | 0000 History: In the initial Qemu implementation (e1833e1), the mask 0x783F0000 was used for saving MSR in SRR1. But all the bits 32:47 were cleared during RFI restoring. This was wrong. The commit 2ada0ed explains that this breaks Altivec. Indeed, bit 38 (for Altivec support) must be saved and restored. The change of 2ada0ed was to restore all the bits of SRR1 to MSR. But it's also wrong. Explanation: As an example, let's see what's happening after a TLB miss. According to the e300 manual (E300CORERM table 5-6), the TLB miss interrupts set the bits 44-47 for KEY, I/D, WAY and S/L. These bits are specifics to the interrupt and must not be copied into MSR at the end of the interrupt. With the current implementation, a TLB miss overwrite bits POW, TGPR and ILE. Fix: It shouldn't be needed to filter-out bits on MSR saving when interrupt occurs. Specific bits overwrite MSR ones in SRR1. But at the end of interrupt (RFI), specifics bits must be cleared before restoring MSR from SRR1. The mask 0x783F0000 apply here. Discussion: The bits of the mask 0x783F0000 are cleared after an interrupt. I cannot find a specification which talks about this but I assume it is the truth since Linux can run this way. Maybe it's not perfect but it's better (works for e300).

2010-05-26Add cache=unsafe parameter to -driveAlexander Graf
Usually the guest can tell the host to flush data to disk. In some cases we don't want to flush though, but try to keep everything in cache. So let's add a new cache value to -drive that allows us to set the cache policy to most aggressive, disabling flushes. We call this mode "unsafe", as guest data is not guaranteed to survive host crashes anymore. This patch also adds a noop function for aio, so we can do nothing in AIO fashion.
