To support device-less protocol-stacks only ports, we can use a
Virt I/O Linux kernel flavor, and export the lx_kit/lx_emul parts
not depending on platform API and devices.
Ref #4397
* Drivers have to use lx_kit/memory_dma.cc
* Protocol-stacks use lx_kit/memory_non_dma.cc
* Moreover the device-dependent lx_emul parts get removed
from the common lx_emul import rules
Fix#4443
* Unifies the declaration of callbacks which manage driver/client
shared dataspaces
* Move the Linux driver-specific callback implementation to the
lx_emul library from the PC's USB host driver
Fixgenodelabs/genode#4439
The logic got accidentally reversed during the transition from the
legacy USB driver.
Since the function drops error details, this patch adds a diagnostic
message with the error code as returned by the Linux driver.
This patch declares that the pseudo target virtualbox6/services/ does
not produce any build artifact. This allows the adding of virtualbox6
to Sculpt's 'build:' list.
The run script uses core, ld.lib.so, and init from depot packages, thus
these cannot be integrated in the image explicitly from the build
directory.
Also, removed special build of report_rom, which is not subject of the
test.
Fixes#4437
* The problem occured only on OKL4, seL4, and L4/Fiasco
* The test used to continue submitting packets regardless of how many were in
flight
* This commit limits the in-flight packets at the Uplink/Nic connections to 40
each
Ref #4419
This commit changes the touch-click filter to adhere the following
sequence:
touch (physical)
press (artifically generated)
release (artificially generated)
release_touch (physical)
This order is important because nitpicker's focus handling takes
press/release events into account. If the release-touch event appears
before the release event, nitpicker subsumes the release-touch event
to the sequence that started with the press event, instead of handling
it as a free-standing event.
Issue #4332
By assigning CPU budgets, base-hw's priorities come into effect.
Even though the chosen values are rather guessed than informed, they
yield a visibly improved responsiveness on the Pinephone.
When committing a new entry, the buffer wrapped if the last entry fit
perfectly into the buffer. Otherwise, the length field of the next entry
was set to 0 to mark the new head. Yet, if there was still some padding but not
enough to hold the length field of another entry, we ended up with a
headless buffer.
genodelabs/genode#4430
Since the head of the buffer is marked by a zero-length entry, we must
only write the length field if a new head was set. Otherwise, the
consumer might already read the new entry and not find the new head as a stop
condition.
genodelabs/genode#4430
When a device got already acquired by a platform session client, do not
return the same capability again, even if the same platform session
client requested it. Therefore, make doubtful behaviour of client components
visible, and do not have to struggle with Platform::Device instances
instantiated multiple times, which care of the lifetime of the device
capability internally.
Fixgenodelabs/genode#4379
Genode code already expects MMU to be disabled when starting the
kernel. It is enabled eventually in Bootstrap::Platform::enable_mmu,
after setting up translation tables. Unfortunately nothing ensures
this is actually the case. If MMU happens to be enabled when entering
the kernel things go downhill pretty fast after we start messing with
TTBR.
This patch ensures MMU is disabled for EL1, EL2, EL3 dependent on the
exception level of the CPU core, which is entering the kernel.
This should allow base-hw to start correctly on Quartz64 A board.
The `lookup_translation` function got introduced and is used only in the
context to proof whether a cache maintainance function can be executed
safely by the kernel. Unfortunately, it did not checked write permissions,
which can lead to permission faults. This commit restricts the lookup
function to only succeed when the target page is writeable. Consequently,
the lookup function gets renamed to `lookup_rw_translation`.
Fixgenodelabs/genode#4348
* Switch from the legacy usb_host driver to the new PC version
in recipes and automated tests
* Update documentation snippets
* Remove outdated, unused usb_rndis run-script
