Userland can now interface with processes by writing/reading from
`/proc/<pid>/<entry>`
It can send signals, for example `echo 15 > /proc/1/signal`
|
|
Incomplete but still very cool
|

Current method is also really bad since it uses multiple copies when it
should instead just copy to the send buffer of the network card
directly. But I have other things that I want to prioritize first.

Apparently getting the current TSC is a expensive operation. This change
had a significant improvements for I/O heavy applications.

The incorrect timer was being used for TCP ACK flush
|
|
Now it appears to be sufficiently good at producing a distinct seed at
each boot without using a /etc/seed file. Previously it did not do this.
Of course this is nowhere near cryptographically secure but randomness
does assist with things such as kmalloc.

This can speed up boot times since CMOS would otherwise have to wait
before it could perform a read/write call. Now it gets triggered by a
interrupt.
|
|
This makes use of TSC and now provides a file system interface for
userland programs to change the system time.

This caused certain addreses which where not RAM memory to be assigned
to virtual addresses incorrectly. This caused a significant slowdown
when running it with KVM due to constantly having to exit the VM if the
OS writes to memory that is not RAM.
This fix increased the performance of KVM significantly and improved TCG
performance.

Now all interrupts go through a common stub which will make certain
signal handlers easier to implement

It will now also create a corresponding /dev/sd* device for each
detected SATA drive. The filesystem still writes using the ATA driver.
This should be fixed soon.

Currently certain parts of the code are taken from osdev wiki as there
seems to be very little documentation that I can find on how H2D FIS is
structured. Those parts, especially some of the uglier parts of the
example code will be rewritten/changed.

Previously this would be hardcoded but now it can be detected by the
bootloader and passed in via the multiboot header.
|
|
This is to allow both the kernel and the userland to share certain
header files and to make the folder structure a bit more clear.
