Also add slightly richer parse errors now that we can include a string
literal with returned errors.
This will allow us to use TRY() when working with JSON data.
The memory and CPU graphs fail to display anything when the memory size
is larger than 2**31 bytes, because of the small range of int. This
commit makes replaces the type with size_t. Hopefully nobody will have
18 quintillion bytes of memory before this gets replaced. :^)
This small patch allows SystemMonitor's Stack tab to show the name of
the ELF object to which the displayed address refers to. This gives a
bit more of contextual information to the viewer.
A better to show this is probably a table, but I'm not that familiar yet
with the GUI framework in general, so I'm keeping things simple.
Casting u64 to float is probably not a safe thing to do. Also, keep
time deltas in u64 values as they can easily wrap between calculations.
This fixes CPU usage calculation when a process is spinning in a loop.
Previously all memory values on the performance was formatted as KiB,
but with such formatting it can be quite hard to read large numbers
(as mentioned by Andreas on todays office hours livestream :^)).
This patch makes use of the human readable formatting utilies and
displays them in an easier to read format.
Combine the "PCI devices" and "Processors" tabs into a "Hardware" tab.
And then remove the "Interrupts" tab because the number of received
IRQ's per device is not really useful information to expose in this GUI.
If the user needs this, he can check lsirq.
This allows for typing [8] instead of [8, 8, 8, 8] to specify the same
margin on all edges, for example. The constructors follow CSS' style of
specifying margins. The added constructors are:
- Margins(int all): Sets the same margin on all edges.
- Margins(int vertical, int horizontal): Sets the first argument to top
and bottom margins, and the second argument to left and right margins.
- Margins(int top, int vertical, int bottom): Sets the first argument to
the top margin, the second argument to the left and right margins,
and the third argument to the bottom margin.
Previously the argument order for Margins was (left, top, right,
bottom). To make it more familiar and closer to how CSS does it, the
argument order is now (top, right, bottom, left).
In #9373, /usr/local/bin was added to the unveiled directories to make
symbolization work on ports. This directory only exists if at least one
port is installed, so unveil would fail with ENOENT if we had none.
Most of the models were just calling did_update anyway, which is
pointless since it can be unified to the base Model class. Instead, code
calling update() will now call invalidate(), which functions identically
and is more obvious in what it does.
Additionally, a default implementation is provided, which removes the
need to add empty implementations of update() for each model subclass.

Add a column named 'Link status' to the Network tab in SystemMonitor
showing the speed and duplex if the link is up.
Add the link speed behind the existing text in the applet or show
'down' if the link is down.
Since this was missing, ProcessStateModel never received
model_did_update, and it was possible for the ProcessModel index to go
stale and show another process.
Fixes#9129.
We can use kill(pid,0) to check for kill permissions instead of relying
on file path access. Using 0 as signal does error checking but does not
send a signal.
Applications previously had to create a GUI::Menubar object, add menus
to it, and then call GUI::Window::set_menubar().
This patch introduces GUI::Window::add_menu() which creates the menubar
automatically and adds items to it. Application code becomes slightly
simpler as a result. :^)
This switches tracking CPU usage to more accurately measure time in
user and kernel land using either the TSC or another time source.
This will also come in handy when implementing a tickless kernel mode.
As threads come and go, we can't simply account for how many time
slices the threads at any given point may have been using. We need to
also account for threads that have since disappeared. This means we
also need to track how many time slices we have expired globally.
However, because this doesn't account for context switches outside of
the system timer tick values may still be under-reported. To solve this
we will need to track more accurate time information on each context
switch.
This also fixes top's cpu usage calculation which was still based on
the number of context switches.
Fixes#6473
We already use PAE for the NX bit, but this changes the PhysicalAddress
structure to be able to hold 64 bit physical addresses. This allows us
to use all the available physical memory.
