...
Right now, only the framebuffer supports this system call, to query its dimensions.

Kernel: Remove /dev/uptime
...
This information can now be fetched with clock_gettime.

Devices: Return EOF after first read for some devices
...
Still not optimal.

This is a huge step forward!! bc actually runs now, without echo or backspace, but it runs!!

This file contains how many milliseconds have passed since boot at the time of reading it :)

Devices: Add a new RandomDevice :)
...
This new device uses the seeded Mersenne PRNG we use in the kernel.
This device is not meant for regular userspace use, but more for userspace to seed their own PRNGs from.
If the DeviceFS is mounted at /dev, this device can be found at /dev/random.

VFS: Implement a new type of Node, VFS_DEVICE
...
This is used to differentiate normal files from devices.
2022-10-12 15:22:34 +02:00

Devices: Tell a device which name you want it to be instantiated with
...
This allows us to create a device in any path, with any filename.

Devices: Add a new Serial device
...
This device permits userspace to interface with the serial port.
2022-10-12 10:44:30 +02:00
e764647133
Devices: add a new ConsoleDevice
...
This new device is the userspace interface to the text console/tty.

VersionDevice: Ignore offset instead of erroring out + set flags to 0
2022-10-11 21:04:14 +02:00

VFS, DeviceFS: Implement a device filesystem
...
For now, we just have a version device. (this will allow us to get rid of sys_getversion!!)
More should be implemented soon.
