status = "okay" means the device is operational. We should ignore
devices that have a different status property value.
The BCM2835TimerDriver force disable hack can be removed, since that
timer is disabled in the Pi 4 devicetree.
But we have to introduce another hack that force enables the Pi 3 system
timer, as we otherwise wouldn't have any timer that we support for the
Pi 3.
Make the MemoryType used by mmap() configurable by
File::vmobject_and_memory_type_for_mmap overrides (previously called
vmobject_for_mmap).
All mmap()s were previously MemoryType::Normal.
If we're drawing a transform with a negative scale, we have to go
through the slow path since draw_scaled_bitmap() is unable to flip
images.
Fixes a regression from the 2nd commit in #24465.
Some assembly files were previously inconsistently formatted.
- Use 4 spaces for indentation
- Use `.L` as the local label prefix
- Remove trailing whitespace
We don't have any text relocations in the kernel anymore.
This linker argument was added in bd6dc5ccec as a temporary workaround.
Removing this argument won't cause text relocations to be reported for
aarch64 and riscv64, as we currently compile the kernel with `--no-pie`
on those architectures.
This pseudoinstruction causes text relocations, as it stores the target
address in literal pools inside .text.
The bss clearing code now also matches the RISC-V implementation.
This writes a bitmap that has pixels that are identical between
the two input images blended with 0.5 alpha against white, and
differing pixels are highlighted in red.
Use like so:
imgcmp --write-diff-image diff.webp image1.png image2.webp
This option causes the window to not resize automatically on guest
display resolution changes.
QEMU has this option enabled by default when using virtio-gpu.
Due to optimiser shenanigans in the tree alternative form, some
JumpNonEmpty ops might be moved before their Checkpoint instruction.
It is safe to assume the distance between the nonexistent checkpoint and
the current op is zero, so just do that.

Repeat's 'offset' field is a bit odd in that it is treated as a negative
offset, causing a backwards jump when positive; the optimizer didn't
correctly model this behaviour, which caused crashes and misopts when
dealing with Repeats.
This commit fixes that behaviour.
