Roger Pau Monne fbcc8b2926 libxc: remove broken endianess gate on lz4 decompressor
The lz4 decompressor had wrongly implemented a gate between
little-endian and big-endian versions of get_unaligned_le{16/32},
which turns out to be broken on all architectures supported by Xen,
because __LITTLE_ENDIAN is not defined. Instead of trying to fix
this, just implement the little-endian version and remove the switch.

Wei Liu ab4440112b xl / libxl: push parsing of SSID and CPU pool ID down to libxl
This patch pushes parsing of "init_seclabel", "seclabel",
"device_model_stubdomain_seclabel" and "pool" down to libxl level.

Originally the parsing is done in xl level, which is not ideal because
libxl won't have the truely relevant information. With this patch libxl
holds important information by itself.

The libxl IDL is extended to hold the string of labels and pool name.
And if there those strings are present they take precedence over the
numeric representations.

As all relevant structures (libxl_dominfo etc) have a field called
X_name / X_label now, a string is also copied there so that callers
won't have to do ID to name / label translation.

In order to be compatible with users of older versions of libxl, this
patch also defines LIBXL_HAVE_SSID_LABEL and LIBXL_HAVE_CPUPOOL_NAME. If
they are defined, the respective strings are available. And if those
strings are not NULL, libxl will do the parsing and ignore the numeric
values.

Dario Faggioli 6e4ecc6d58 sched: DOMCTL_*vcpuaffinity works with hard and soft affinity
by adding a flag for the caller to specify which one he cares about.

At the same time, enable the caller to get back the "effective affinity"
of the vCPU. That is the intersection between cpupool's cpus, the (new)
hard affinity and, for soft affinity, the (new) soft affinity. In fact,
despite what has been successfully set with the DOMCTL_setvcpuaffinity
hypercall, the Xen scheduler will never run a vCPU outside of its hard
affinity or of its domain's cpupool.

This happens by adding another cpumap to the interface and making both
the cpumaps IN/OUT parameters (for DOMCTL_setvcpuaffinity, they're of
course out-only for DOMCTL_getvcpuaffinity).

Wei Liu 0ae765d434 libxl/gentypes.py: special-case KeyedUnion map handle generation
Generate JSON map handle according to KeyedUnion discriminator.

The original JSON output for a keyed union is like:
 {
   ...
   "u" : { FIELDS }
   ...
 }

The discriminator is not generated, so that the parser won't be able to
figure out the fields in the incoming stream.

So we need to change this to something more sensible. For example, for
keyed union libxl_domain_type, which has a discriminator called "type",
we generate following for HVM guest:
 {
   ...
   "type.hvm" : { HVM FIELDS }
   ...
 }

Parser then can know the type of this union and how to interpret the
incoming stream.

Note that we change the existing API here. However the original output is
quite broken anyway, we cannot make sensible use of it and I doubt that
there's existing user of existing API. So we are acutally fixing a
problem.

wrong.

Wei Liu c28219f035 xl: remove parsing of "vncviewer" option in xl domain config file
Print out a warning and suggest user use "-V" option when invoking "xl
create". Also remove that option in manpage. This will introduce a
minor functional regression but it's very easy to work around.

The rationale behind this change is that, this option is actually not
part of domain configuration. It just affects whether a vncviewer
should be automatically spawn, but has nothing to do with how a domain
should be constructed. And this option is also bogus, considering if you
migrate a domain to a remote host and the receiver spawns a vncviewer on
the receiving side then it either dies silently or occupies resource.

Since the domain build needs to know the size of the DTB we create placeholder

Ian Campbell 45d9867837 tools: arm: prepare domain builder for multiple banks of guest RAM
Prepare for adding more banks of guest RAM by renaming a bunch of defines
as RAM0 and replacing variables with arrays and introducing loops.

Also in preparation switch to using GUEST_RAM0_BASE explicitly instead of
implicitly via dom->rambase_pfn (while asserting that they must be the same).
This makes the multiple bank case cleaner (although it looks a bit odd for
now).

GUEST_RAM_BASE is defined as the address of the lowest RAM bank, it is used in
tools/libxl/libxl_dom.c to call xc_dom_rambase_init().

Lastly for now ramsize (total size) and rambank_size[0] (size of first bank)
are the same, but use the appropriate one for each context.

Ian Campbell db57c96dc0 tools: arm: refactor code to setup guest p2m and fill it with RAM
This will help when we have more guest RAM banks.

Mostly code motion of the p2m_host initialisation and allocation loop into the
new function populate_guest_memory, but in addition in the caller we now
initialise the p2m all the INVALID_MFN to handle any holes, although in this
patch we still fill in the entire allocated region.

Ian Campbell 180596a1eb tools: arm: move magic pfns out of guest RAM region
Because toolstacks (at least libxl) only allow RAM to be specified in 1M
increments these two pages were effectively costing 1M of guest RAM space.

Since these pages don't actually need to live in RAM just move them out.

With this a guest can now use the full 768M of the address space reserved
for RAM. (ok, not that impressive, but it simplifies things later)

Ian Campbell 5a959f44ed tools: arm: report an error if the guest RAM is too large
Due to the layout of the guest physical address space we cannot support more
than 768M of RAM before overrunning the area set aside for the grant table. Due
to the presence of the magic pages at the end of the RAM region guests are
actually limited to 767M.

Catch this case during domain build and fail gracefully instead of obscurely
later on.
