-This README briefly explains how to use the pci and pci_auto
-code in arch/mips/kernel. The code was ported from PowerPC and
-modified slightly. It has been tested pretty well on PPC on some
-rather complex systems with multiple bridges and devices behind
-each bridge. However, at the time this README was written, the
-mips port was tested only on boards with a single pci bus and
-no P2P bridges. It's very possible that on boards with P2P
-bridges some modifications have to be made. The code will
-evolve, no doubt, but currently every single mips board
-is doing its own pcibios thing and it has become a big
-mess. This generic pci code is meant to clean up the mips
-pci mess and make it easier to add pci support to new boards.
-
-inside the define for your board in arch/mips/config.in.
-For example, the Galileo EV96100 board looks like this:
-
-if [ "$CONFIG_MIPS_EV96100" = "y" ]; then
- define_bool CONFIG_PCI y
- define_bool CONFIG_MIPS_GT96100 y
- define_bool CONFIG_NEW_PCI y
- define_bool CONFIG_SWAP_IO_SPACE y
-fi
-
-
-Next, if you want to use the arch/mips/kernel/pci code, which has the
-pcibios_init() function, add
-
-define_bool CONFIG_NEW_PCI y
-
-inside the define for your board. Again, the EV96100 example above
-show NEW_PCI turned on.
-
-
-Now you need to add your files to hook in your pci configuration
-cycles. Usually you'll need only a couple of files named something
-like pci_fixups.c and pci_ops.c. You can copy the templates
-provided and fill in the code.
-
-The file pci_ops.c should contain the pci configuration cycles routines.
-It also has the mips_pci_channels[] array which contains the descriptors
-of each pci controller.
-
-The file pci_fixups.c contains a few routines to do interrupt fixups,
-resources fixups, and, if needed, pci bios fixups.
-
-Usually you'll put your pci_fixups.c file in your board specific directory,
-since the functions in that file are board specific. The functions in
-pci_ops.c, on the other hand, are usually pci controller specific so that
-file could be shared among a few different boards using the same
-pci controller.

+ * IRQ stack entry and exit:
+ *
+ * Unlike i386, UML doesn't receive IRQs on the normal kernel stack
+ * and switch over to the IRQ stack after some preparation. We use
+ * sigaltstack to receive signals on a separate stack from the start.
+ * These two functions make sure the rest of the kernel won't be too
+ * upset by being on a different stack. The IRQ stack has a
+ * thread_info structure at the bottom so that current et al continue
+ * to work.
+ *
+ * to_irq_stack copies the current task's thread_info to the IRQ stack
+ * thread_info and sets the tasks's stack to point to the IRQ stack.
+ *
+ * from_irq_stack copies the thread_info struct back (flags may have
+ * been modified) and resets the task's stack pointer.
+ *
+ * Tricky bits -
+ *
+ * What happens when two signals race each other? UML doesn't block
+ * signals with sigprocmask, SA_DEFER, or sa_mask, so a second signal
+ * could arrive while a previous one is still setting up the
+ * thread_info.
+ *
+ * There are three cases -
+ * The first interrupt on the stack - sets up the thread_info and
+ * handles the interrupt
+ * A nested interrupt interrupting the copying of the thread_info -
+ * can't handle the interrupt, as the stack is in an unknown state
+ * A nested interrupt not interrupting the copying of the
+ * thread_info - doesn't do any setup, just handles the interrupt
+ *
+ * The first job is to figure out whether we interrupted stack setup.
+ * This is done by xchging the signal mask with thread_info->pending.
+ * If the value that comes back is zero, then there is no setup in
+ * progress, and the interrupt can be handled. If the value is
+ * non-zero, then there is stack setup in progress. In order to have
+ * the interrupt handled, we leave our signal in the mask, and it will
+ * be handled by the upper handler after it has set up the stack.
+ *
+ * Next is to figure out whether we are the outer handler or a nested
+ * one. As part of setting up the stack, thread_info->real_thread is
+ * set to non-NULL (and is reset to NULL on exit). This is the
+ * nesting indicator. If it is non-NULL, then the stack is already
+ * set up and the handler can run.

+/*
+ * This is my current (2007-04-25) understanding of how this dongle is supposed
+ * to work. This is based on reverse-engineering and examination of the packet
+ * data sent and received by the WinXP driver using USBSnoopy. Feel free to
+ * update here as more of this dongle is known:
+ *
+ * General: Unlike the other USB IrDA dongles, this particular dongle exposes,
+ * not two bulk (in and out) endpoints, but two *interrupt* ones. This dongle,
+ * like the bulk based ones (stir4200.c and mcs7780.c), requires polling in
+ * order to receive data.
+ * Transmission: Just like stir4200, this dongle uses a raw stream of data,
+ * which needs to be wrapped and escaped in a similar way as in stir4200.c.
+ * Reception: Poll-based, as in stir4200. Each read returns the contents of a
+ * 8-byte buffer, of which the first byte (LSB) indicates the number of bytes
+ * (1-7) of valid data contained within the remaining 7 bytes. For example, if
+ * the buffer had the following contents:
+ * 06 ff ff ff c0 01 04 aa
+ * This means that (06) there are 6 bytes of valid data. The byte 0xaa at the
+ * end is garbage (left over from a previous reception) and is discarded.
+ * If a read returns an "impossible" value as the length of valid data (such as
+ * 0x36) in the first byte, then the buffer is uninitialized (as is the case of
+ * first plug-in) and its contents should be discarded. There is currently no
+ * evidence that the top 5 bits of the 1st byte of the buffer can have values
+ * other than 0 once reception begins.
+ * Once valid bytes are collected, the assembled stream is a sequence of
+ * wrapped IrDA frames that is unwrapped and unescaped as in stir4200.c.
+ * BIG FAT WARNING: the dongle does *not* reset the RX buffer in any way after
+ * a successful read from the host, which means that in absence of further
+ * reception, repeated reads from the dongle will return the exact same
+ * contents repeatedly. Attempts to be smart and cache a previous read seem
+ * to result in corrupted packets, so this driver depends on the unwrap logic
+ * to sort out any repeated reads.
+ * Speed change: no commands observed so far to change speed, assumed fixed
+ * 9600bps (SIR).
