aliguori [Fri, 12 Dec 2008 16:41:40 +0000 (16:41 +0000)]
Replace posix-aio with custom thread pool

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).

pci: add default pci subsystem id for all devices (Gerd Hoffman)

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.

Fix handling of disk-only snapshots (Kevin Wolf)

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.

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.

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

Thomas Bogendoerfer (from #mipslinux) tested the behaviour of a real

even addresses for data register.

parameter by a mask one.
Incidentally, keyboard now works on OpenBSD 2.3, which accesses i8042

at target-sh4/helper.c:449, using new mmio rule introduced by #5849
This masking is a nice trick to realize P4/A7 duality of SH registers.
But, IMHO, it is logically wrong.

Most of SH4 cpu control registers in P4 area(0xfc000000...0xffffffff) have
one more address called A7 which is usually P4 address with upper 3bits masked.
This is an address only appears in TLB's physical address part.

Current code use trick writing drivers as if they are really in A7
(that's why you see many *_A7 in hw/sh*.c), and using translation P4 to A7.

LSI53C895A: Handle empty SCRIPTS opcode (Justin Chevrier)

Basically after each DMA transfer the Openserver driver would issue an
empty (0) SCRIPTS opcode. As the opcode is essentially a NOP it has no
second DWORD and therefore the DSP should only be incremented by 4 bytes
instead of the 8 bytes we currently do.

Here's a snippet of the log:

lsi_scsi: Data ready tag=0x100d9 len=16384
...
lsi_scsi: SCRIPTS dsp=068c5e50 opcode 01000400 arg 07a09000

lsi_scsi: SCRIPTS dsp=068c5e58 opcode 00000000 arg 01000400
lsi_scsi: Wrong phase got 1 expected 0

Note the 2nd DWORD after the empty opcode; the next opcode in the DMA
transfer sequence. As can be expected the address after that has the next
DMA address to use.

After the attached patch the DMA transfer is able to complete successfully:
