      hw/intc/arm_gic: Create outbound FIQ lines · 44f55296
      由 Fabian Aggeler 提交于 
      Create the outbound FIQ lines from the GIC to the CPUs; these are
used if the GIC has security extensions or grouping support.

      hw/sd: Don't pass BlockBackend to sd_reset() · 16b781aa
      由 Peter Maydell 提交于 
      The only valid BlockBackend to pass to sd_reset() is the one for
the SD card, which is sd->blk. Drop the second argument from this
function in favour of having it just use sd->blk.

      armv7m_nvic: systick: Reload the RELOAD value and count down only if ENABLE bit is set · 165cdaf8
      由 Adrian Huang 提交于 
      Consider the following pseudo code to configure SYSTICK (The
recommended programming sequence from "the definitive guide to the
arm cortex-m3"):
    SYSTICK Reload Value Register = 0xffff
    SYSTICK Current Value Register = 0
    SYSTICK Control and Status Register = 0x7

The pseudo code "SYSTICK Current Value Register = 0" leads to invoking
systick_reload(). As a consequence, the systick.tick member is updated
and the systick timer starts to count down when the ENABLE bit of
SYSTICK Control and Status Register is cleared.

The worst case is that: during the system initialization, the reset
value of the SYSTICK Control and Status Register is 0x00000000.
When the code "SYSTICK Current Value Register = 0" is executed, the
systick.tick member is accumulated with "(s->systick.reload + 1) *
systick_scale(s)". The systick_scale() gets the external_ref_clock
scale because the CLKSOURCE bit of the SYSTICK Control and Status
Register is cleared. This is the incorrect behavior because of the
code "SYSTICK Control and Status Register = 0x7". Actually, we want
the processor clock instead of the external reference clock.

This incorrect behavior defers the generation of the first interrupt.

The patch fixes the above-mentioned issue by setting the systick.tick
member and modifying the systick timer only if the ENABLE bit of
the SYSTICK Control and Status Register is set.

In addition, the Cortex-M3 Devices Generic User Guide mentioned that
"When ENABLE is set to 1, the counter loads the RELOAD value from the
SYST RVR register and then counts down". This patch adheres to the
statement of the user guide.

      qemu-nbd: only send a limited number of errno codes on the wire · ca441480
      由 Paolo Bonzini 提交于 
      Right now, NBD includes potentially platform-specific error values in
the wire protocol.

Luckily, most common error values are more or less universal: in
particular, of all errno values <= 34 (up to ERANGE), they are all the
same on supported platforms except for 11 (which is EAGAIN on Windows and
Linux, but EDEADLK on Darwin and the *BSDs).  So, in order to guarantee
some portability, only keep a handful of possible error codes and squash
everything else to EINVAL.

This patch defines a limited set of errno values that are valid for the
NBD protocol, and specifies recommendations for what error to return
in specific corner cases.  The set of errno values is roughly based on
the errors listed in the read(2) and write(2) man pages, with some
exceptions:

- ENOMEM is added for servers that implement copy-on-write or other
  formats that require dynamic allocation.

- EDQUOT is not part of the universal set of errors; it can be changed
  to ENOSPC on the wire format.

- EFBIG is part of the universal set of errors, but it is also changed
  to ENOSPC because it is pretty similar to ENOSPC or EDQUOT.

Incoming values will in general match system errno values, but not
on the Hurd which has different errno values (they have a "subsystem
code" equal to 0x10 in bits 24-31).  The Hurd is probably not something
to which QEMU has been ported, but still do the right thing and
reverse-map the NBD errno values to the system errno values.

The corresponding patch to the NBD protocol description can be found at
http://article.gmane.org/gmane.linux.drivers.nbd.general/3154.

      rules.mak: Force CFLAGS for all objects in DSO · d24697e1
      由 Fam Zheng 提交于 
      Because of the trick of process-archive-undefs, all .mo objects, even
with --enable-modules, are dependencies of executables.

This breaks CFLAGS propogation because the compiling of module object
will happen too early before building for DSO.

With GCC 5, the linking would fail because .o doesn't have -fPIC. Also,
BUILD_DSO will be missed. (module-common.o will have it, so the stamp
symbol was still liked in .so).

Fix the problem by forcing the CFLAGS on individual .o-cflags during
unnest-vars.
