b78aae9bb6 hw/arm/smmu-common: Fix devfn computation in smmu_iommu_mr
smmu_iommu_mr() aims at returning the IOMMUMemoryRegion corresponding
to a given sid. The function extracts both the PCIe bus number and
the devfn to return this data. Current computation of devfn is wrong
as it only returns the PCIe function instead of slot | function.

Fixes 32cfd7f39e ("hw/arm/smmuv3: Cache/invalidate config data")

a98ff0ec2b ppc patch queue 2018-07-09
Here's a final pull request before tomorrow's hard freeze.
 
 There are a number of fixes and improvements to the sm501 display
 driver (not strictly ppc related, but used only on ppc and SH).
 There's also a handful of unrelated fixes.
 
 Whether all the sm501 changes are bugfixes is somewhat debatable, but
 Peter has indicated he's ok with merging those for 3.0.

51b0d834c4 sam460ex: Make sam460ex_load_device_tree() handle all errors internally
sam460ex_load_device_tree() handles nearly all possible errors by simply
exiting (within helper functions and macros).  It handles two early error
cases by returning an error.

There's no particular point to this, so make it handle those directly as
well, removing the need for the caller to handle a failure.  As a bonus it
gives us more specific error messages.

ad633de6f5 sam460ex: Check for errors from libfdt functions
In a couple of places sam460ex_load_device_tree() calls "raw" libfdt
functions which can fail, but doesn't check for error codes.  At best,
if these fail the guest will be silently started in a non-standard state,
or it could fail entirely.

Fix this by using the _FDT() helper macro which aborts on a libfdt failure.

it missed setting the default display type to stdvga for both PReP machines

Update the MachineClass for both prep and 40p machines so that the default
std(vga) display adapter is the default if no options are specified

If we compare with the macro for ppc64le, we can see
sizeof(r->element[0]) should be used instead of sizeof(r->element).

And VINSERT uses only u8, u16, u32 and u64, so the maximum value
of sizeof(r->element[0]) is 8

e20122ff0f checkpatch: handle token pasting better
The mechanism to find possible type tokens can sometimes be confused and go into an
infinite loop.  This happens for example in QEMU for a line that looks like

         uint## BITS ##_t S = _S, T = _T;                            \
         uint## BITS ##_t as, at, xs, xt, xd;                        \

Because the token pasting operator does not have a space before _t, it does not
match $notPermitted.  However, (?x) is turned on in the regular expression for
modifiers, and thus ##_t matches the empty string.  As a result, annotate_values
goes in an infinite loop.

The solution is simply to remove token pasting operators from the string before
looking for modifiers.  In the example above, the string uintBITS_t will be
evaluated as a candidate modifier.  This is not optimal, but it works as long
as people do not write things like a##s##m, and it fits nicely into sub
possible.

For a similar reason, \# should be rejected always, even if it is not
at end of line or followed by whitespace.

The same patch was sent to the Linux kernel mailing list.

02693cc4f4 i386: fix '-cpu ?' output for host cpu type
Since commit d6dcc5583e, '-cpu ?' shows the description of the
X86_CPU_TYPE_NAME("max") for the host CPU model:

Enables all features supported by the accelerator in the current host

instead of the expected:

KVM processor with all supported host features

or

HVF processor with all supported host features

This is caused by the early use of kvm_enabled() and hvf_enabled() in
a class_init function. Since the accelerator isn't configured yet, both
helpers return false unconditionally.

A QEMU binary will only be compiled with one of these accelerators, not
both. The appropriate description can thus be decided at build time.

2729d79d49 pr-helper: Rework socket path handling
When reviewing Paolo's pr-helper patches I've noticed couple of
problems:

1) socket_path needs to be calculated at two different places
(one for printing out help, the other if socket activation is NOT
used),

2) even though the default socket_path is allocated in
compute_default_paths() it is the only default path the function
handles. For instance, pidfile is allocated outside of this
function. And yet again, at different places than 1)

ee8c13b814 pr-helper: avoid error on PR IN command with zero request size
After reading a PR IN command with zero request size in prh_read_request,
the resp->result field will be uninitialized and the resp.sz field will
be also uninitialized when returning to prh_co_entry.

If resp->result == GOOD (from a previous successful reply or just luck),
then the assert in prh_write_response might not be triggered and
uninitialized response will be sent.

The fix is to remove the whole handling of sz == 0 in prh_co_entry.
Those errors apply only to PR OUT commands and it's perfectly okay to
catch them later in do_pr_out and multipath_pr_out; the check for
too-short parameters in fact doesn't apply in the easy SG_IO case, as
it can be left to the target firmware even.

The result is that prh_read_request does not fail requests anymore and
prh_co_entry becomes simpler.

a428594042 RISC-V: SoCify SiFive boards and connect GEM
This series has three tasks:
  1. To convert the SiFive U and E machines into SoCs and boards
  2. To connect the Cadence GEM device to the SiFive U board
  3. Fix some device tree problems with the SiFive U board
 
 After this series the SiFive E and U boards have their SoCs split into
 seperate QEMU objects, which can be used on future boards if desired.
 
 The RISC-V Virt and Spike boards have not been converted. They haven't
 been converted as they aren't physical boards, so it doesn't make a
 whole lot of sense to split them into an SoC and board. The only
 disadvantage with this is that they now differ to the SiFive boards.
 
 This series also connect the Cadence GEM device to the SiFive U board.
 There are some interrupt line changes requried before this is possible.

19c9a18f45 docker: add linux-user powered cross builder for QEMU
We can't use cross compilers in the current Debian stable and Debian
sid is sketchy as hell. So for powerpc fall back to dog-fooding our
own linux-user to do the build.

As we can only build the base image with a suitably configured
source tree we fall back to checking for its existence when we can't
build it from scratch. However this does mean you don't have to keep
a static powerpc-linux-user in your active configuration just to
update the cross build image.

dc338fdb07 docker: add special rule for deboostrapped images
We might as well have a custom rule for this. For one thing the
dependencies are different. As the primary dependency for
docker-image-% could never be docker-image-debian-bootstrap we can
drop that test in the main rule as well.

Missing EXECUTABLE, DEB_ARCH and DEB_TYPE are treated as hard faults
now. We also error out if the EXECUTABLE file isn't there. We should
really do this with a dependency on any source rules but currently
subdir-FOO-linux-user isn't enough on a clean build.
