This allows referencing an arbitrary number of IOMMU devices within a
<devices> node, e.g.:
<device>
<io_mmu name="foobar"/>
</device>
The specified name is supposed to refer to an existing device in the
devices ROM. The platform driver automatically acquires known IOMMU
devices whenever they become available so that the device object can be
looked up from the platform-driver-owned devices.
genodelabs/genode#4761
With this change, platform-specific code is able to define factories that
acquire IOMMU devices to be used by the platform driver.
genodelabs/genode#4761
The method did not handle device changes properly. When a new policy
does not contain an owned device any more, we must consider this device
as changed and release it. Moreover, the warning messages were interchanged.
genodelabs/genode#4761
"-cpu phenom" does not support all CPU instructions necessary with
gcc 12 toolchain update issuing more SSSE3, e.g. pshufb.
Additionally, remove good/bad Qemu version check of outdated versions.
Issue genodelabs/genode-world#329
When a GPU session is destroyed, remove vgpu of session from scheduling
and as possible active vgpu. Otherwise, page faults might occur in case
already destroyed vgpu object is referenced during interrupt handling.

error: ‘void operator delete(void*, Genode::Deallocator&)’ called on pointer returned from a mismatched allocation function [-Werror=mismatched-new-delete]
Issue #4827Fixes#4848
An early version of nitpicker used a pointer as 'owner' with the null
pointer representing nitpicker's built-in views, which are nowadays
represented by 'Main::_global_view_ower'. The null-pointer check is a
left-over from the earlier days.
Fixes#4847
Since repos/base/board/pc/devices is empty, the run script no longer
works on PC. Nobody noticed because the use case of this run script -
as development test loop for the ps2 and fb_sdl - are better served by
other scenarios nowadays, e.g., using declaring 'build: ps2' for a
custom Sculpt OS build.
Removed in the context of issue #4860.
Bit 0:3 indicate which of the (up to) 16 supported LBA formats is
used for this namespace. Instead of only looking at those bits the
driver looked at the complete 0:7 bits. Those, however, also include
information on how metadata may be transferred. That leads to using
the wrong index for reading the LBA format.
Fixes#4832.
If the DMA memory allocation alignment is unfortunate (not natural size
aligned), the IOMMU (AMD/INTEL) may not use larger(super) pages with effects
on the page table walk frequency and TLB caching.
Issue #4820
Before scheduling we check if the execlist is empty. When many clients
are present, the bits might not be cleared by hardware yet. Before the
watchdog timer would trigger, because we scheduled nothing. Now we try
serval times, even if this fails, we still schedule because in the worst
case only a preemption would happen.
issue #4820
This patch promotes the event of an exiting child to become immediately
reported, reducing delays for management components that watch the exit
status of children.
Fixes#4814
