      tcp/mips: Change TCG_AREG0 (fp -> s0) · d80e20a1
      由 Stefan Weil 提交于 
      Register fp (frame pointer) is a bad choice for compilations
without optimisation, because the compiler makes heavy use
of this register (so the resulting code crashes).

Register s0 had been used for TCG_AREG1 in earlier releases,
but was no longer used and is now free for TCG_AREG0.

The resulting code works for compilations without
optimisation (tested with qemu mips in qemu mips
on x86 host).

      sh_pci: fix memory and I/O access · 1ce4fad9
      由 Aurelien Jarno 提交于 
      Since commit 8da3ff18 ("MMIO callback
interface changes"), the addresses passed to the I/O functions are an
offset to the start of the area. As a consequence, there is no need to
correct the address using the value of IOBR. This make possible the use
of the default MMIO functions. Moreover the addresses are now remaped
when the value if IOBR change.

The memory area corresponds to the devices behing the PCI bus, it should
not be mapped by the PCI controller. Remove the corresponding code.

      Fix SIGFPE for vnc display of width/height = 1 · 09e96924
      由 Chris Webb 提交于 
      During boot, the screen gets resized to height 1 and a mouse click at this
point will cause a division by zero when calculating the absolute pointer
position from the pixel (x, y). Return a click in the middle of the screen
instead in this case.

      net: remove broken net_set_boot_mask() boot device validation · 69ff4e9d
      由 Eduardo Habkost 提交于 
      There are many problems with net_set_boot_mask():

1) It is broken when using the device model instead of "-net nic". Example:
   $ qemu-system-x86_64 -device rtl8139,vlan=0,id=net0,mac=52:54:00:82:41:fd,bus=pci.0,addr=0x4 -net user,vlan=0,name=hostnet0 -vnc 0.0.0.0:0 -boot n
   Cannot boot from non-existent NIC
   $
2) The mask was previously used to set which boot ROMs were supposed to be
   loaded, but this was changed long time ago. Now all ROM images are loaded,
   and SeaBIOS takes care of jumping to the right boot entry point depending on
   the boot settings.
3) Interpretation and validation of the boot parameter letters is done on
   the machine type code. Examples: PC accepts only a,b,c,d,n as valid boot
   device letters. mac99 accepts only a,b,c,d,e,f.

As a side-effect of this change, qemu-kvm won't abort anymore if using "-boot n"
on a machine with no network devices. Checking if the requested boot device is
valid is now a task for the BIOS or the machine-type code.

      tcg/arm: correctly save/restore registers in prologue/epilogue · 5c689207
      由 Aurelien Jarno 提交于 
      Since commit 6113d6d3 QEMU crashes
on ARM hosts. This is not a bug of this commit, but a latent bug
revealed by this commit.

The TCG code is called through a procedure call using the prologue
and epilogue code. This code does not save and restore enough registers.
The "Procedure Call Standard for the ARM Architecture" says:

  A subroutine must preserve the contents of the registers r4-r8, r10,
  r11 and SP (and r9 in PCS variants that designate r9 as v6).

The current code only saves and restores r9 to r11, and misses r4 to
r8. The patch fixes that by saving r4 to r12. Theoretically there is
no need to save and restore r12, but an even number of registers have
to be saved as per EABI.

      workaround for cmd646 bmdma register access while no dma is active · 18a21890
      由 Igor V. Kovalenko 提交于 
      This is a workaround only, and is a partial revert
of a few changes to BMDMAState which removed pci_dev
field on the way.

- cmd646 pci_from_bm() expects bm->unit value to
correspond with bm data being passed to callback
as opaque pointer. This breaks when write to dma
control register of second channel happens when no
dma operation is in progress, so bm->unit is zero
for second channel, and pci_from_bm() returns garbage
pointer. Crash happens shortly after that while
dereferencing that pointer.

v0->v1: cleaned up dead code from pci_from_bm.
