Tests: Improve munmap-test
We now Unmap page aligned and check if the regions were really unmappped etc.
Tests: Cleanup Munmap-test
added a cleanup and removed a useless cast
This implements a fallback to munmap that unmaps multiple regions at a
time, with splitting some when needed.
The way it is implemented is possibly not optimal, due to it searching
without looking into the cache
Instead of blindly resetting every AHCI port, let's just reset only the
controller by default. The user can still request to reset everything
with a new kernel boot argument called ahci_reset_mode which is set
by default to "controller", so the code will only invoke an HBA reset.
This kernel boot argument can be set to 3 different values:
1. "controller" - reset the HBA and skip resetting AHCI ports
2. "none" - don't reset anything, so we rely on the firmware to
initialize the AHCI HBA and ports for us.
3. "complete" - reset the AHCI HBA and ports.
Instead of waiting for the AHCI HBA to reset the signature after SATA
reset sequence, let's just check if the Port x Serial ATA Status
register was set to value 3, indicating that device was detected
and phy communication was established.
The intention is to make the boot to be faster, therefore we should
decrease the time deltas in timeout loops to allow earlier break
from these.
Also, there's no need to wait 10 milliseconds before setting
the interface state to "no action request" during the reset sequence.
Running the tests will be moved to a separate test command which can
then leverage the availability of different targets and run either unit
tests on the host or the image in QEMU in self-test mode. :^)
- Only call ensure_toolchain for non-lagom targets
- Use host addr2line, we can't expect the i686 toolchain's addr2line to
support the host's binary executable format
- Don't export SERENITY_ARCH and TOOLCHAIN_DIR, don't need them anymore
When multiple images are dragged and dropped onto the image widget,
QuickShow will use LibDesktop::Launcher to launch a new instance
of QuickShow for each item, rather than spawn a child QuickShow
process for each item with posix_spawn.
This allows `proc` and `exec` pledges to be removed :^)
