* Add new heap manager.
* Convert OHCI driver to use new heap manager.
* Convert UHCI driver to use new heap manager.
* Convert EHCI driver to use new heap manager.
* Convert XHCI driver to use new heap manager.
* Convert SMP to use new heap manager.
* Add a "usbinit" boot option to handle various buggy USB devices.
This replaces the "keyboard=buggy-usb" option, and adds a second
workaround to handle the problem seen in issue #107.
* Add preliminary support for TTY Serial/UART (#15)
* Use shadow_buffer instead of VGA buffer to get a framebuffer-agnostic TTY supprot
* Added menu browsing & inputs from Serial TTY (#15)
* Add fix for degree symbol on TTY. Correct serial.c & serial.h file created with CRLF (#15)
* Move tty_error_redraw() to insure correct redraw when a error occurs
* Many reindent / cleanup
* Various optimization from @martinwhitaker comments
The old barrier implementation was very slow when running on a multi-socket
machine (pcmemtest issue 16).
The new implementation provides two options:
- when blocked, spin on a thread-local flag
- when blocked, execute a HLT instruction and wait for a NMI
The first option might be faster, but we need to measure it to find out. A
new boot command line option is provided to select between the two, with a
third setting that uses a mixture of the two.
When using a legacy BIOS, the memory regions used by the BIOS are well
defined. This is not the case when using a UEFI BIOS. So include the
stack area in the BSS so the loader knows how much memory to allocate,
and check we have space to relocate the program to either low or high
memory.
There are still some assumptions in the USB driver code that need to
be fixed.
