Also, duplicate data in dbg() and klog() calls were removed.
In addition, leakage of virtual address to kernel log is prevented.
This is done by replacing kprintf() calls to dbg() calls with the
leaked data instead.
Also, other kprintf() calls were replaced with klog().
Now the ACPI & PCI code is more safer, because we don't use raw pointers
or references to objects or data that are located in the physical
address space, so an accidental dereference cannot happen easily.
Instead, we use the PhysicalAddress class to represent those addresses.
System components that need an IRQ handling are now inheriting the
InterruptHandler class.
In addition to that, the initialization process of PATAChannel was
changed to fit the changes.
PATAChannel, E1000NetworkAdapter and RTL8139NetworkAdapter are now
inheriting from PCI::Device instead of InterruptHandler directly.
As suggested by Joshua, this commit adds the 2-clause BSD license as a
comment block to the top of every source file.
For the first pass, I've just added myself for simplicity. I encourage
everyone to add themselves as copyright holders of any file they've
added or modified in some significant way. If I've added myself in
error somewhere, feel free to replace it with the appropriate copyright
holder instead.
Going forward, all new source files should include a license header.
ACPI subsystem includes 3 types of parsers that are created during
runtime, each one capable of parsing ACPI tables at different level.
ACPIParser is the most basic parser which is essentialy a parser that
can't parse anything useful, due to a user request to disable ACPI
support in a kernel boot parameter.
ACPIStaticParser is a derived class from ACPIParser, which is able to
parse only static data (e.g. FADT, HPET, MCFG and other tables), thus
making it not able to parse AML (ACPI Machine Language) nor to support
handling of hardware events and power management. This type of parser
can be created with a kernel boot parameter.
ACPIDynamicParser is a derived class from ACPIStaticParser, which
includes all the capabilities of the latter, but *should* implement an
AML interpretation, (by building the ACPI AML namespace) and handling
power & hardware events. Currently the methods to support AML
interpretation are not implemented.
This type of parser is created automatically during runtime if the user
didn't specify a boot parameter related to ACPI initialization.
Also, adding strncmp function definition in StdLib.h, to be able to use
it in ACPIStaticParser class.
