This displays statistics regarding frame timings and number of pixels
rendered.
Timings are based on the time between draw_debug_overlay() invocations.
This measures actual number of frames presented to the user vs. wall
clock time so this also includes everything the app might do besides
rendering.
Triangles are counted after clipping. This number might actually be
higher than the number of triangles coming from LibGL.
Pixels are counted after the initial scissor and coverage test. Pixels
rejected here are not counted. Shaded pixels is the percentage of all
pixels that made it to the shading stage. Blended pixels is the
percentage of shaded pixels that were alpha blended to the color buffer.
Overdraw measures how many pixels were shaded vs. how many pixels the
render target has. e.g. a 640x480 render target has 307200 pixels. If
exactly that many pixels are shaded the overdraw number will read 0%.
614400 shaded pixels will read as an overdraw of 100%.
Sampler calls is simply the number of times sampler.sample_2d() was
called.
This modifies sys$chown to allow specifying whether or not to follow
symlinks and in which directory.
This was then used to implement lchown and fchownat in LibC and LibCore.
Add an option to enable NVMe storage device as the boot
drive.
To enable NVMe support, run the following:
$ SERENITY_NVME_ENABLE=1 Meta/serenity.sh run i686 root=/dev/nvme0n1
Add a basic NVMe driver support to serenity
based on NVMe spec 1.4.
The driver can support multiple NVMe drives (subsystems).
But in a NVMe drive, the driver can support one controller
with multiple namespaces.
Each core will get a separate NVMe Queue.
As the system lacks MSI support, PIN based interrupts are
used for IO.
Tested the NVMe support by replacing IDE driver
with the NVMe driver :^)
This commit adds support the following properties to theming:
Flags:
- IsTitleCenter: true if the title should be centered.
Metrics:
- BorderThickness: The border width.
- BorderRadius: The border corner radius.
LexicalPath is a 'heavier' object than a String that is mainly used for
path parsing and validation, we don't actually need any of that in
GitRepo and its related files, so let's move to String :^)
I've also done some east-const conversion in the files that I was
editing for the string change.
If we do not decrement `m_buffered_size` whenever we read data from the
buffer, we end up saying that there are more lines available when we
reach the end of file. This bug caused callers to read garbage data.
This also fixes an incorrect condition in an if statement. The separator
candidate is searched for in `remaining_buffer`, so the separator's
length should be compared against that.
This patch adds the bare bones of the new Filter Gallery.
For now, only the gml and the basic layout got added, a fairly boringw
indow pops up when "Filter Gallery" is called.
The code for the Model used by the TreeView is taken in large parts from
HackStudio's VariableModel.
Calls to link_up() in the E1000 driver would read the link state
directly from the hardware on every call. This had negative
performance impact in high throughput situations since link_up()
is called every time an IP packet's route is resolved.
This patch takes inspiration from the RTL8139 network adapter where
the link state is stored in a bool and only updated when the hardware
generates an interrupt related to link state change.
After this change I measured a ~9% increase in TCP Tx throughput
using:
cat /dev/zero | nc <host_IP> <host_port> from the Serenity VM to my
host machine
This exposed a missing exception check in parseWebAssemblyModule(),
which could throw but still return a normal completion (which currently
works as we check VM::exception() at the right point, but breaks when
moving everything to exceptions).
If the location started at 0, and / or the length was 0, it would
originally turn out to be a location of { -1, -1 } when LibDiff was
finished parsing, which was incorrect.
To fix this, we only subtract 1 if `start` or `length` isn't 0.
In certain cases, an index might be invalid in the unstaged files view.
We must check if this index is valid before attempting to read the
index's data.
Since years don't have a constant amount of seconds because they can be
leap years no constant will work in all cases. We now test a timezone in
both the positive and negative direction and check that at least one
worked. Assuming years are at least 2 days long this will always pass
at least one test.
This matches the text of the spec, and is more correct since the
variable is being updated, not defined it.
See: https://github.com/tc39/proposal-temporal/commit/5ab1822

I also changed `test_year += 1` to `test_year++` for consistency with
step 11.c that has the same description.
Naturally, this means that a command with a failing redirection will
not start, and so will terminate the pipeline (if any).
This also applies to the `exit` run when the shell is closed, fixing a
fun bug there as well (thanks to Discord user Salanty for pointing that
out) where closing the terminal (i.e. I/O error on the tty) with a
failing `exit` command would make the shell retry executing `exit` every
time, leading to an eventual stack overflow.
By using the binary from our build of binutils, we can be sure that `nm`
supports demangling symbols, so we can avoid spawning a separate
`c++filt` process.
