90e151e2c4 gpu: add 'complete' RPC call
This call allows for checking if the given execution buffer has been
completed and complements the completion signal. Initially the GPU
multiplexer always sent such a signal when the currently scheduled
execution buffer has been completed. During enablement of the 'iris'
driver it became necessary to properly check of sequence number.

In case of the Intel GPU multiplexer the sequence numbers are
continous, which prompted the greater-than-or-equal check in the
DRM back end. By hidding this implementation detail behind the
interface, GPU drivers are free to deal with sequence numbers any
way they like and allows for polling in the client, where the
completion signal is now more of a progress signal.

e37792ce94 gpu: introduce information dataspace
The current info implementation (as RPC) is limited in a few ways:

  * The amount of data that may be transferred is constrained by the
    underlying base platform
  * Most information never changes during run time but is copied
    nonetheless
  * The information differs depending on the used GPU device and
    in its current implementation only contains Intel GPU specific
    details

With this commit the 'info' RPC call is replaced with the
'info_dataspace' call that transfers the capability for the dataspace
containing the information only. This is complemented by a client
local 'attached_info' call that allows for getting typed access to
the information. The layout of the information is moved to its own
and GPU-specific header file, e.g., 'gpu/info_intel.h'

3b40790e02 gpu: use Buffer_id to identify buffers

choose its own local identifier that is linked to the underlying
capability.

b157256a2b uplink client: Add missing space in warning message.
Right now the warning about failure to forward packet from driver to
uplink RX connection reads:

  "exception while trying to forward packet from driverto Uplink
   connection TX"

Add missing space between "driver" and "to".

60980045ea virtio_nic: Increase default TX & RX virtqueue sizes.
32KB is a rather small value. The driver can cope with it now, but
it does not perform as well as it should. This visible especially
in scenarions like nic_router_flood where we still often hit
synchronous wait path. Bump the size to 256kB.

880cd3a490 virtio_nic: Fix packet transmission handling.
The problem can be seen when running nic_router_flood scenarion on arm
qemu_virt boards. With the amount of data this scenario tries to send
the driver quickly complains it has failed to push data into TX VirtIO
queue. After this warning message is printed nothing really happens and
after a while the test scenario fails.

The fact that we can't write all available data to the device is not
unexpected. VirtIO queue size is slected at initialization time and we
don't change it during driver lifetime. It can be tweaked via driver
config, but this does not change the fact that we'll always be able to
produce more data packets than we have free space in the VirtIO queue.

IMO the expected behavior of the driver in such case should be to:
1. Notify the device there is data to process.
2. Wait for the device to process at least part of it.
3. Retry sending queued packets.

One could expect returning Transmit_result::RETRY from _drv_transmit_pkt
would produce such result. Unfortunately it seems that Uplink_client_base
treats RETRY return value as indication of link being down. It'll retry
sending the packet only after the device notifies it the link is once
again up. This is the reason why nothing happens when running
nic_router_flood on top of virtio_nic driver. The link never goes down
in this case so once we fill the TX VirtIO queue and tell the base class
to retry the send, we'll be stuck waiting for link up change event
which will never arrive.

To fix this problem, when sending a packet to the device fails, do a
synchrnonus TX VirtIO queue flush (tell device there is data to process
and wait until its done with it).

With this fix in place nic_router_flood test scenario passes on both arm
qemu_virt boards.

c0a7696c71 tool/dts/extract: convert regex strings to latin1
The former encoding was UTF-8, which works quite well if LC_CTYPE is
ensured to be an UTF-8 codeset (e.g., en_US.UTF-8 or C.UTF-8 . But, if
LC_CTYPE is set to C or latin1 for example, the Tcl regex library enters
an infinite loop because of unexpected characters used as markers
n the strings (e.g., SECTION SIGN U+00A7).

Therefore, the extract tool was converted to latin1 with the following
commands and now works for LC_CTYPE C and UTF-8 codesets.

   iconv -f utf-8 -t latin1 tool/dts/extract > /tmp/e
   cp /tmp/e tool/dts/extract

3daa94ff2e gpu/intel: Add support for Gen9+
This commit contains features and buf fixes:

* Catch errors during resource allocation

* Because Mesa tries to allocate fence (hardware) registers for each
  batch buffer execution, do not allocate new fences for buffer objects
  that are already fenced

* Add support for global hardware status page. Each context additionally
  has a per-process hardware status page, which we used to set the
  global hardware status page during Vgpu switch. This was obviously
  wrong. There is only one global hardware status page (set once during
  initialization) and a distinct per-process page for contexts.

* Write the sequence number of the currently executing batch buffer to
  dword 52 of the per-process hardware status page. We use the pipe line
  command with QW_WRITE (quad word write), GLOBAL_GTT_IVB disabled
  (address space is per-process address space), and STORE_DATA_INDEX
  enabled (write goes to offset of hardware status page). This command
  used to write to the scratch page. But Linux now uses the first
  reserved word of the per-process hardware status page.

* Add Gen9+ WaEnableGapsTsvCreditFix workaround. This sets the "GAPS TSV
  Credit fix Enable" bit of the Arbiter control register (GARBCNTLREG)
  as described by the documentation this bit should be set by the BIOS
  but is not on most Gen9/9.5 platforms. Not setting this bit leads to
  random GPU hangs.

* Increase the context size from 20 to 22 pages for Gen9. On Gen8 the
  hardware context is 20 pages (1 hardware status page + 19 ring context
  register pages). On Gen9 the size of the ring context registers has
  increased by two pages to 21 pages or 81.3125 KBytes as the IGD
  documentation states.

* The logical ring size in the ring buffer control of the execlist
  context has to be programmed with number of pages - 1. So 0 is 1 page.
  We programmed the actual number of pages before, leading to ring
  buffer execution of NOOPs if page behind our ring buffer was empty or
  GPU hangs if there was data on the page.

59b23bc7e1 libdrm: Iris - execute batch buffer synchronous
* Wait for for completion before return from 'execbuffer2'. This makes
  buffer execution synchronous.

* Because the Iris driver manages the virtual address space of the GPU
  and creates one GEM context for each batch buffer we have to map/unmap
  all buffer objects before and after batch buffer execution.

d072c408ab dde_linux: call init_page_count for each page
The lx_emul_virt_to_pages implementation initialized the page ref
counter only for the first page, leaving the remaining elements in
uninitialized state. This, in turn, rendered the Linux page_pool (as
used by the emac network driver) ineffective, ultimately leading the a
memory leak. The fix changes the call of 'init_page_count' to take the
loop variable as argument.

e6c915ae06 libssh port: immediate mode for ssh poll
This patch adds a switch to internal poll function in libssh that
allows to force this function to immediately return without actually
polling for data and in consequence processing this data. This switch
is used to avoid calling callback functions when flushing output
streams which caused locks due to recursive access to internal
ssh_terminal sessions registry.

f1b72d0281 cxx: define delete operator with alignm. arg
Using 'alignas' in declarations might cause GCC to request for an
implementation of 'operator delete(void*, unsigned long, std::align_val_t)'
although it might actually never be called. This commit adds a dummy
implementation to 'cxx/new_delete.cc' that does nothing more than printing an
error to the log that a proper implementation is missing. This approach is
coherent with our treatment of other global delete operators.

ebd140cacb reconstructible: respect alignment of payload
If one has an object X that has a minimum alignment requirement specified
through 'alignas' this requirement is normally inherited by objects that have
object X as member, and by those that have objects as member that have X as
member, and so on... . However, this chain used to get silently interrupted
(dropping the minimum alignment requirement to 8 again) at objects that are
managed with Genode::Reconstructible or Genode::Constructible. In order to fix
this, the commit ensures that Genode::Reconstructible (and therefore also
Genode::Constructible) has at least the minimum alignment requirement (using
'alignas') as the object it manages.
