pnv/xive2: Configure Virtualization Structure Tables through the PC

Both the virtualization layer (VC) and presentation layer (PC) need to
be configured to access the VSTs. Since the information is redundant,
the xive model combines both into one set of tables and only the
definitions going through the VC are kept. The definitions through the
PC are ignored. That works well as long as firmware calls the VC for
all the tables.

For the NVG and NVC tables, it can make sense to only configure them
with the PC, since they are only used by the presenter. So this patch
allows firmware to configure the VST tables through the PC as well.
The definitions are still shared, since the VST tables can be set
through both the VC and/or PC, they are dynamically re-mapped in
memory by first deleting the memory subregion.

pnv/xive2: Add NVG and NVC to cache watch facility

The cache watch facility uses the same register interface to handle
entries in the NVP, NVG and NVC tables. A bit-field in the 'watchX
specification' register tells the table type. So far, that bit-field
was not read and the code assumed a read/write to the NVP table.

This patch allows to read/write entries in the NVG and NVC table as
well.

pnv/xive: Support cache flush and queue sync inject with notifications

Adds support for writing a completion notification byte in memory
whenever a cache flush or queue sync inject operation is requested by
software. QEMU does not cache any of the XIVE data that is in memory and
therefore it simply writes the completion notification byte at the time
that the operation is requested.

pnv/xive2: XIVE2 Cache Watch, Cache Flush and Sync Injection support

XIVE offers a 'cache watch facility', which allows software to read/update
a potentially cached table entry with no software lock. There's one such
facility in the Virtualization Controller (VC) to update the ESB and END
entries and one in the Presentation Controller (PC) to update the
NVP/NVG/NVC entries.

Each facility has 4 cache watch engines to control the updates and
firmware can request an available engine by querying the hardware
'watch_assign' register of the VC or PC. The engine is then reserved and
is released after the data is updated by reading the 'watch_spec' register
(which also allows to check for a conflict during the update).
If no engine is available, the special value 0xFF is returned and
firmware is expected to repeat the request until an engine becomes
available.

In this last queue for 8.1 we have a lot of fixes and improvements all
around: SMT support for powerNV, XIVE fixes, PPC440 cleanups, exception
handling cleanups and kvm_pph.h cleanups just to name a few.

Thanks everyone in the qemu-ppc community for all the contributions for

pnv/xive2: Always pass a presenter object when accessing the TIMA

The low-level functions to access the TIMA take a presenter object as
a first argument. When accessing the TIMA from the IC BAR,
i.e. indirect calls, we currently pass a NULL pointer for the
presenter argument. While it appears ok with the current usage, it's
dangerous. And it's pretty easy to figure out the presenter in that
context, so this patch fixes it.

pnv/xive2: Fix TIMA offset for indirect access

Direct TIMA operations can be done through 4 pages, each with a
different privilege level dictating what fields can be accessed. On
the other hand, indirect TIMA accesses on P10 are done through a
single page, which is the equivalent of the most privileged page of
direct TIMA accesses.

The offset in the IC bar of an indirect access specifies what hw
thread is targeted (page shift bits) and the offset in the
TIMA being accessed (the page offset bits). When the indirect
access is calling the underlying direct access functions, it is
therefore important to clearly separate the 2, as the direct functions
assume any page shift bits define the privilege ring level. For
indirect accesses, those bits must be 0. This patch fixes the offset
passed to direct TIMA functions.

It didn't matter for SMT1, as the 2 least significant bits of the page
shift are part of the hw thread ID and always 0, so the direct TIMA
functions were accessing the privilege ring 0 page. With SMT4/8, it is
no longer true.

The fix is specific to P10, as indirect TIMA access on P9 was handled
differently.

pnv/xive2: Allow indirect TIMA accesses of all sizes

Booting linux on the powernv10 machine logs a few errors like:

Invalid read at addr 0x38, size 1, region 'xive-ic-tm-indirect', reason: invalid size (min:8 max:8)
Invalid write at addr 0x38, size 1, region 'xive-ic-tm-indirect', reason: invalid size (min:8 max:8)
Invalid read at addr 0x38, size 1, region 'xive-ic-tm-indirect', reason: invalid size (min:8 max:8)

Those errors happen when linux is resetting XIVE. We're trying to
read/write the enablement bit for the hardware context and qemu
doesn't allow indirect TIMA accesses of less than 8 bytes. Direct TIMA
access can go through though, as well as indirect TIMA accesses on P9.
So even though there are some restrictions regarding the address/size
combinations for TIMA access, the example above is perfectly valid.

This patch lets indirect TIMA accesses of all sizes go through. The
special operations will be intercepted and the default "raw" handlers
will pick up all other requests and complain about invalid sizes as
appropriate.
