This adds a counter to the debug overlay that displays the average
percentage of SIMD lane utilization.
This number represents the number of pixels that were output for each
quad. A utilization of 100% means that all 4 SIMD lanes were used and
no pixels were masked out before being written to the color buffer.
Now, each new filter only has to describe how to actually change
the bitmaps, and the common logic of pulling out the bitmap from the
layer, and marking the action as done, etc is all handled in the
`Filter` base class.
This also makes it possible to apply filters to external bitmaps,
which are not embedded in a `Layer` (which we can use to preview
filters in the future!)
This makes interrupting `sleep 10; echo hi` not print `hi` anymore,
which is the expected behaviour anyway.
Also fixes the problem with fast-running loops "eating" interrupts and
not quitting.
Running `./package.sh interactive` in a port directory will
spawn a new shell with the serenity build environment set up.
This makes porting software much easier as build commands can
be run interactively instead of having to modify package.sh
just to test things.
Add them in `<Kernel/API/Device.h>` and use these to provides
`{makedev,major,minor}` in `<sys/sysmacros.h>`. It aims to be more in
line with other Unix implementations and avoid code duplication in user
land.
The documentation tooltip and parameters hint tooltip initialization
functions are now fallible and now call try_set_main_widget
instead of set_main_widget. They are only called by Editor's new
custom try_create function.
build_process_window now uses try_set_main_widget and might return an
error. process_properties_action handles a possible error by simply
not updating the process window if an error occured while building it.
Briefly flash the menubar menu containing the keyboard shortcut action
to give the user immediate visual feedback on their interaction with the
system.
Pressing the F2 key on files that the user doesn't have permission was
opening the file name for editing.
This patch fixes the issue disabling the file name editing when the user
doesn't have permission to do it.
To reproduce the issue:
1) Open the File Manager
2) Click on the /etc directory
3) Select any file
4) Press the F2 key
5) Update the file name
Not all drivers need the PhysicalPage output parameter while creating
a DMA buffer. This overload will avoid creating a temporary variable
for the caller
The cacheable parameter to allocate_kernel_region should be explicitly
set to No as this region is used to do physical memory transfers. Even
though most architectures ignore this even if it is set, it is better
to make this explicit.
