20 hourskern/amd64: Attempt to dequeue on a cores first goIan Moffett
When a CPU core first starts up, it has no proceses to assign to itself. This commit ensures that the processor will right away start trying to find tasks to grab from its runqueue. Signed-off-by: Ian Moffett <ian@osmora.org>

Signed-off-by: Ian Moffett <ian@osmora.org>
41 hourskern: 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>
43 hourskern: 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>
3 dayskernel/amd64: Add PS/2 scancode buffering + IO tapIan Moffett
This commit introduces scancoding buffering as well as an I/O tap so that it may be exposed outside of the driver Signed-off-by: Ian Moffett <ian@osmora.org>

Signed-off-by: Ian Moffett <ian@osmora.org>
3 dayskernel/amd64: cpu: Implement 'ioapic_common' stubIan Moffett
This implementation walks through the entire table of registered interrupt handlers and calls each driver handler. The driver is to return a value of 1 if the interrupt is theirs and has been handled, otherwise it is to return 0. The handling core is to respoond to a 1 by exiting the table walk early, and responds to a 0 by continuing. Signed-off-by: Ian Moffett <ian@osmora.org>

3 dayskernel/amd64: intr: Make interrupt table globalIan Moffett
This commit makes the interrupt table global so it can be accessed through assembly. Signed-off-by: Ian Moffett <ian@osmora.org>
3 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>
3 dayskern/amd64: Add interrupt registration frameworkIan Moffett
This commit introduces the interrupt registration framework for L5 and accounts for I/O APIC IRQ inputs, and interrupt priority levels encoded within bits 7:4 of the interrupt vector Signed-off-by: Ian Moffett <ian@osmora.org>
3 dayskern/amd64: ioapic: Add ISA IRQ to GSI conversionIan Moffett
Introduce a helper function to convert legacy ISA IRQ numbers to the GSI numbers assigned to an I/O APIC pin Signed-off-by: Ian Moffett <ian@osmora.org>

Signed-off-by: Ian Moffett <ian@osmora.org>
4 dayskern: os: Add I/O tap frameworkIan Moffett
The I/O tap framework provides a way to bypass the typical device filesystem interface for applications where more direct access would be beneficial. Signed-off-by: Ian Moffett <ian@osmora.org>
