- *  18-Nov-2004 BJD  Removed error for loading onto stopped channel
- *  10-Nov-2004 BJD  Ensure all external symbols exported for modules

- *  08-Aug-2004 BJD  Apply rmk's suggestions
- *  21-Jul-2004 BJD  Ported to linux 2.6
- *  12-Jul-2004 BJD  Finished re-write and change of API
- *  06-Jul-2004 BJD  Rewrote dma code to try and cope with various problems
- *  23-May-2003 BJD  Created file
- *  19-Aug-2003 BJD  Cleanup, header fix, added URL
- *
- * This file is based on the Sangwook Lee/Samsung patches, re-written due
- * to various ommisions from the code (such as flexible dma configuration)
- * for use with the BAST system board.
- *
- * The re-write is pretty much complete, and should be good enough for any
- * possible DMA function

-/* This function must be called with xtime_lock held.
- * It was inspired by Steve McCanne's microtime-i386 for BSD.  -- jrs
- * 
- * However, the pc-audio speaker driver changes the divisor so that
- * it gets interrupted rather more often - it loads 64 into the
- * counter rather than 11932! This has an adverse impact on
- * do_gettimeoffset() -- it stops working! What is also not
- * good is that the interval that our timer function gets called
- * is no longer 10.0002 ms, but 9.9767 ms. To get around this
- * would require using a different timing source. Maybe someone
- * could use the RTC - I know that this can interrupt at frequencies
- * ranging from 8192Hz to 2Hz. If I had the energy, I'd somehow fix
- * it so that at startup, the timer code in sched.c would select
- * using either the RTC or the 8253 timer. The decision would be
- * based on whether there was any other device around that needed
- * to trample on the 8253. I'd set up the RTC to interrupt at 1024 Hz,
- * and then do some jiggery to have a version of do_timer that 
- * advanced the clock by 1/1024 s. Every time that reached over 1/100
- * of a second, then do all the old code. If the time was kept correct
- * then do_gettimeoffset could just return 0 - there is no low order
- * divider that can be accessed.
- *
- * Ideally, you would be able to use the RTC for the speaker driver,
- * but it appears that the speaker driver really needs interrupt more
- * often than every 120 us or so.
- *
- * Anyway, this needs more thought....		pjsg (1993-08-28)

- *
- * 1) We handle one interrupt and return, sitting in a loop and moving across
- *    all the pending IRQ bits in the cause register is _NOT_ the answer, the
- *    common case is one pending IRQ so optimize in that direction.
- *
- * 2) We need not check against bits in the status register IRQ mask, that
- *    would make this routine slow as hell.
- *
- * 3) Linux only thinks in terms of all IRQs on or all IRQs off, nothing in
- *    between like BSD spl() brain-damage.
- *
- * Furthermore, the IRQs on the MIPS board look basically (barring software
- * IRQs which we don't use at all and all external interrupt sources are
- * combined together on hardware interrupt 0 (MIPS IRQ 2)) like:
- *
- *	MIPS IRQ	Source
- *      --------        ------
- *             0	Software (ignored)
- *             1        Software (ignored)

- *             7        R4k timer (what we use)
- *
- * Note: On the SEAD board thing are a little bit different.
- *       Here IRQ 2 (hw0) is wired to the UART0 and IRQ 3 (hw1) is wired
- *       wired to UART1.
- *
- * We handle the IRQ according to _our_ priority which is:
- *
- * Highest ----     R4k Timer
- * Lowest  ----     Combined hardware interrupt
- *
- * then we just return, if multiple IRQs are pending then we will just take
