Commit 32761257c0b9fa7ee04d2871a6e48a41f119c469 enabled qemu_ld/st optimization unconditionally for some hosts. The TCG interpreter still does not support this kind of optimization.

2012-11-18build: replace weak symbols with a static libraryPaolo Bonzini18-89/+89
Weak symbols were a nice idea, but they turned out not to be a good one. Toolchain support is just too sparse, in particular llvm-gcc is totally broken. This patch uses a surprisingly low-tech approach: a static library. Symbols in a static library are always overridden by symbols in an object file. Furthermore, if you place each function in a separate source file, object files for unused functions will not be taken in. This means that each function can use all the dependencies that it needs (especially QAPI stuff such as error_setg). Thus, all stubs are placed in separate object files and put together in a static library. The library then is linked to all programs.

2012-11-16virtio-rng: add rate limiting supportAnthony Liguori3-8/+64
This adds parameters to virtio-rng-pci to allow rate limiting the entropy a guest receives. An example command line: $ qemu -device virtio-rng-pci,max-bytes=1024,period=1000 Would limit entropy collection to 1Kb/s. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-11-16virtio-rng: hardware random number generator deviceAmit Shah9-0/+341
The Linux kernel already has a virtio-rng driver, this is the device implementation. When the guest asks for entropy from the virtio hwrng, it puts a buffer in the vq.

2012-11-16ehci: handle dma errorsGerd Hoffmann3-19/+62
Starting with commit 1c380f9460522f32c8dd2577b2a53d518ec91c6d dma transfers can actually fail. This patch makes ehci keep track of the busmaster bit in pci config space, by setting/clearing the dma_context pointer. Attempts to dma without context will result in raising HSE (Host System Error) interrupt and stopping the host controller. This patch fixes WinXP not booting with a usb stick attached to ehci. Root cause is seabios activating ehci so you can boot from the stick, and WinXP clearing the busmaster bit before resetting the host controller, leading to ehci actually trying dma while it is disabled.

2012-11-16ehci: Don't verify the next pointer for periodic qh-s and qtd-sHans de Goede1-3/+6
While testing the move to async packet handling for interrupt endpoints I noticed that Windows-XP likes to play tricks with the next pointer for periodic qh-s, so we should not fail qh / qtd verification when it changes.

2012-11-16ehci: Better detection for qtd-s linked in circlesHans de Goede1-3/+6
Windows links interrupt qtd-s in circles, which means that when interrupt endpoints return USB_RET_ASYNC, combined with the recent "ehci: Retry to fill the queue while waiting for td completion" patch, we keep adding the tds to the queue over and over again, as we detect the circle from fill_queue, but we call it over and over again ... This patch fixes this by changing the circle detection to also detect circling into tds already queued up previously.

2012-11-16ehci: Fixup q->qtdaddr after cancelling an already completed packetHans de Goede1-0/+4
This avoids the q->qtdaddr == p->qtdaddr asserts we have triggering, when a queue contains multiple completed packages when we cancel the queue. I triggered this with windows7 + async interrupt endpoint handling (*) + not detecting circles in ehci_fill_queue() properly, which makes the qtd validation in ehci_fill_queue fail, causing cancellation of the queue on every mouse event ... *) Which is not going upstream as it will cause loss of interrupt events on migration.

2012-11-16ehci: Don't access packet after freeing itHans de Goede1-4/+5

2012-11-16vga: fix mmio vga register mappingGerd Hoffmann1-3/+4
2012-11-16vga: fix bochs alignment issueGerd Hoffmann2-3/+3
The bochs dispi interface traditionally uses port 0x1ce as 16bit index register and port 0x1cf as 16bit data register. The later is unaligned, and probably for that reason the the data register was moved to 0x1d0 for non-x86 archs. This patch makes the data register available at 0x1d0 on x86 too. The old x86 location is kept for compatibility reasons, so both 0x1cf and 0x1d0 can be used as data register on x86. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-11-16usb-host: scan for usb devices when the vm startsGerd Hoffmann1-0/+11
Commit a844ed842d9a9d929645c09ae0f52f753d7a02e0 leads to usb-host detecting devices not right after qemu startup because the guest isn't running yet. Instead they are found on the first of the regular usb device poll runs. Which is too late for seabios to see them, so booting from usb sticks fails. Fix this by adding a vm state change handler which triggers a device scan when the vm is started. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
