During interrupt handling the driver masked and cleared interrupts as
recommended in the spec to prevent spurious or unnecessary interrupts
from occurring.
Due to the way the current implementation operates new Block requests
got submitted while handling completions for already finished ones.
Since interrupts where masked at this point the controller did not
generate interrupts when the newly submitted requests got completed.
As the mask/clear optimization is apparently not strictly needed and
according to the spec undefined when using MSI-X it is removed.
Fixes#4684
200 TSC ticks for max measurement duration can get too small on platforms
with high TSC frequencies (e.g., >3GHz) and low CPU frequencies often
caused by HWP configurations. Therefore, we express the measurement
duration in NS (not ticks) and calculate max duration ticks using the
TSC frequency. This way the max duration becomes independent of the TSC
frequency.

This commit enables users of the VMM to define CPU type and count, RAM size,
kernel and initrd ROM names, GIC version, and Virtio devices to be used.
Derived from the configuration values a flattened device-tree blob (DTB) is
generated and transfered to the VM.

Lack of MSI-X support in DDE Linux causes a timeout when the Intel AX211
tries to call back into the driver while loading the PNVM file while
interrupts are still disabled.
With the patch picked up from QubesOS the card works on an X1 Nano G2:

Issue #4663
Until now, requesting optional blobs such as 'iwl-debug-yoyo.bin' has
just failed silently. To support desired blobs such as PNVM firmware,
implement the loading of optional firmware while preserving the nowarn
characteristics of the function.
Issue #4663
Try to allocate within constraint area first. In case the area is exhausted,
try allocation at other memory locations.
The motivation for this is to limit DMA allocations to 4GB (since some
devices require addresses below 4GB). On some platforms there is little
physical RAM in this area (<1GB) and the constrainted area exhausts. In
case an IOMMU is present, RAM at higher locations can still be mapped
below 4GB, which is done in the platform drivers.
issue #4665
Consume '<iommu/>' tag from 'devices' report. In case an IOMMU is
present map physical memory to arbitrary locations within IO page table
range 1K-4G. This way every device PD has access to ~4GB of DMA space.
issue #4665
The platform driver configuration is missing the required 'info'
attribute that allows the 'vesa_fb_drv' to map the proper I/O
memory address of the framebuffer. In addition the driver requires
at least '2' more CAPs, so raise the quota to '110'.
Fixes#4668.
There is one binder with one memory zone per OpenGL context. The patch was
needed before because Genode didn't have proper context support (separate page
tables) leading to binders from one or more context being allocated to the same
GPU address with the same page tables. This was clearly an error and is fixed
with context support.
issue #4664
'_env_ram' allocations can lead to
'Expanding_pd_session_client::try_alloc' quota upgrades, which in turn
may lead to a resource request by the platform driver. Therefore, we
check the available quota within the platform driver before allocations.
This is not an optimal solution.

This patch makes the component graph better reusable for the phone
version of Sculpt. In the phone version, the '+' menu does not exist.
So we need to omit the corresponding button. Furthermore, the storage
dialog is presented in a dedicate section of the GUI instead of
presenting it inside the 'storage' graph node. The phone version
also does not offer the inspect view. So we need to omit the
corresponding buttons.
To prevent caching side-effects of USB DMA memory taken from the packet stream
all allocations of USB packets need to be on separated cachelines at least.

To complement the GPIO support allow for setting and reading input
pins. So far this is needed by drivers that attempt to perform I2C
bit-banging via GPIO pins.
Fixes#4624.
In case the allocation fails for the largest possible connector mode,
try smaller modes. Additional add option to specify maximal resolution.

Increase "assumed" internal kernel memory size based on available memory
to support allocation of framebuffer larger than 16M, which was before
hardcoded.
