2008-12-13TCG x86/x86-64: use move with zero-extend for loads/storesaurel32
Starting with version 4.3, gcc returns the result of a function in rax/eax/ax/al instead of rax/eax, depending of the return type. As a consequence we should use a zero extend moe in TCG loads/stores. See http://gcc.gnu.org/ml/gcc/2008-01/msg00052.html for more details. A big thanks to malc who founds the problem and wrote the x86 patch.

2008-12-13target-i386: SVM: acknowledge interrupt only after it is takenaurel32
SVM specifies that the V_IRQ mask is only to be removed, if the interrupt that is to be delivered actually is delivered. As of the SVM rewrite, this mask is always unmasked when the main cpu loop is processed, leaving a corner case where calling the interrupt handler causes a #PF. In that case (booting Linux / starting gfxboot) the current implementation tells the VMM the interrupt is taken, even though it is not. This patch modifies the VIRQ unmasking to occur after do_interrupt, making gfxboot work again.

2008-12-13x86 cleanupblueswir1
Remove some unnecessary includes, add needed includes, move prototypes to cpu.h to suppress missing prototype warnings. Remove unused functions and prototypes (cpu_x86_flush_tlb, cpu_lock, cpu_unlock, restore_native_fp_state, save_native_fp_state). Make some functions and data static (f15rk, parity_table, rclw_table, rclb_table, raise_interrupt, fpu_raise_exception), they are not used outside op_helper.c anymore. Make some x86_64 and user only code conditional to avoid warnings.

2008-12-12Replace posix-aio with custom thread poolaliguori
glibc implements posix-aio as a thread pool and imposes a number of limitations. 1) it limits one request per-file descriptor. we hack around this by dup()'ing file descriptors which is hideously ugly 2) it's impossible to add new interfaces and we need a vectored read/write operation to properly support a zero-copy API. What has been suggested to me by glibc folks, is to implement whatever new interfaces we want and then it can eventually be proposed for standardization. This requires that we implement our own posix-aio implementation though. This patch implements posix-aio using pthreads. It immediately eliminates the need for fd pooling. It performs at least as well as the current posix-aio code (in some circumstances, even better).

2008-12-11pci: add default pci subsystem id for all devices (Gerd Hoffman)aliguori
This sets a default PCI subsystem ID for all emulated PCI devices. PCI specs require this, so do it. In many cases it is enougth to know the PCI ID to handle a device correctly. Sometimes a device driver must identify the exact piece of hardware (via PCI Subsystem ID) though. What does this patch to qemu devices: Right now the emulated PCI devices have no PCI subsystem ID, only the PCI ID. The discussed patch sets a default PCI subsystem ID for all emulated devices. Which will make the qemu devices look pretty much like in the laptop case: all PCI subsystem IDs will point to qemu by default. If a driver emulates a very specific piece of hardware where it has to emulate more than just the PCI chip, it can overwrite the PCI subsystem ID without problems. The es1370 driver does that for example.

2008-12-11Fix handling of disk-only snapshots (Kevin Wolf)aliguori
When creating a snapshot with multiple qcow2 disks attached, the current behaviour is that qemu creates a disk snapshot on all of them and chooses one to write the VM state to. Despite having the state only in one image, loadvm tries to restore the VM state from the middle of nowhere if you run qemu a second time with only one of the other images attached. In the lucky case it will fail because there simply is no state, but it also can happen that it loads the state of a different snapshot (the one this new one is based upon). The fix is to write a zero VM state size to the images which don't contain the state, and check this in loadvm. I agree that you probably have to provoke such things intentionally to get in a state like this with qemu itself. However, with my second patch that adds snapshot support to qemu-img it could become a reasonable use case to have snapshots with and without VM states on the same image.

This patch adds SH bit handling to sh4's TLB, which is a part of MMU functionality that had not been implemented in qemu.

Even though URC is not needed to be strictly same as HW because it is a random number, this condition is not negligible.

2008-12-10Add 64-bit Block Move support (Direct & Table Indirect) (Ryan Harper)aliguori
This patch adds support for 64-bit Block Move instructions. There are multiple modes for 64-bit Block moves, direct, indirect, and table indirect. This patch implements Direct and Table indirect moves which are needed by 64-bit windows and SYM_CONF_DMA_ADDRESSING_MODE=2 for the Linux sym53c8xx_2 driver respectively. Two helper functions are included to check which mode the guest is using. For 64-bit direct moves, we fetch a 3rd DWORD and store the value in the DBMS register. For Table Indirect moves, we look into the table for which register contains the upper 32-bits of the 64-bit address. This selector value indicates which register to pull the value from and into dnad64 register. Finally, lsi_do_dma is updated to use the approriate register to build a 64-bit DMA address if required. With this patch, Windows XP x64, 2003 SP2 x64, can now install to scsi devices. Linux SYM_CONF_DMA_ADDRESSING_MODE=2 need a quirk fixup in Patch 4 to function properly.

2008-12-10MIPS Magnum: fix memory-mapped i8042aurel32
Current implementation of memory-mapped i8042 controller is atm implemented with an interface shift (it_shift) parameter, like most all memory-mapped devices in Qemu. However, this isn't suitable for MIPS Magnum, where i8042 controller is at 0x80005000 up to 0x80005fff. Thomas Bogendoerfer (from #mipslinux) tested the behaviour of a real machine, and found that odd addresses are for status/command register, and even addresses for data register. Attached patch implements this behaviour by replacing the it_shift parameter by a mask one. Incidentally, keyboard now works on OpenBSD 2.3, which accesses i8042 controller at 0x80005060 and 0x80005061.
