Introduce programming interface based lookups for devices with different kinds of interfaces Signed-off-by: Ian Moffett <ian@osmora.org>
5 dayskern: pci: Get programming interface from deviceIan Moffett
Some devices are identified by very specific programming interfaces, therefore this is important to have. Signed-off-by: Ian Moffett <ian@osmora.org>
5 dayskern: pci: Use LU types instead of classrev fieldIan Moffett
Instead of using bitfields to say which kind identification we are doing, it is a better idea to just use the lookup type directly as it is more scalable Signed-off-by: Ian Moffett <ian@osmora.org>

7 dayslibc: iotap: Add I/O tap syscall interfaceIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
7 dayskern: iotap: Expose I/O taps to userlandIan Moffett
Expose I/O taps to userland using a tap message interface. An application may construct a tap message to send to the kernel requesting data from a specific tap, if there is data, the buffers will be safely populated, otherwise some error returned. An example is accessing the PS/2 keyboard tap: -- char name[] = "i8042.port.0"; char buf[2] = {0, 0}; struct iotap_msg msg = { .opcode = IOTAP_OPC_READ, .buf = buf, .len = len }; ... /* muxtap() may be used */ ... -- Signed-off-by: Ian Moffett <ian@osmora.org>
7 dayskern: security: Improve scalability of MAC checksIan Moffett
The concept of resource borders is mostly used for resources that can easily be mapped into memory, synced and contain attributes. However, some things (e.g., a network resource, keyboard input, etc) may not be great with raw memory mappings. This commit mitigates this problem. Signed-off-by: Ian Moffett <ian@osmora.org>
8 dayskern/amd64: isa: Add PS/2 keyboard prototypeIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
8 dayskern/amd64: Reserve 64 vectors for I/O APIC inputsIan Moffett
This commit reserves the first 64 vectors for the I/O APIC input lines. During an IRQ, each handler will be called to see which one handles it. Signed-off-by: Ian Moffett <ian@osmora.org>
