1As of the Linux 2.6.10 kernel, it is now possible to change the
2IO scheduler for a given block device on the fly (thus making it possible,
3for instance, to set the CFQ scheduler for the system default, but
4set a specific device to use the anticipatory or noop schedulers - which
5can improve that device's throughput).
6
7To set a specific scheduler, simply do this:
8
9echo SCHEDNAME > /sys/block/DEV/queue/scheduler
10
11where SCHEDNAME is the name of a defined IO scheduler, and DEV is the
12device name (hda, hdb, sga, or whatever you happen to have).
13
14The list of defined schedulers can be found by simply doing
15a "cat /sys/block/DEV/queue/scheduler" - the list of valid names
16will be displayed, with the currently selected scheduler in brackets:
17
18# cat /sys/block/hda/queue/scheduler
19noop anticipatory deadline [cfq]
20# echo anticipatory > /sys/block/hda/queue/scheduler
21# cat /sys/block/hda/queue/scheduler
22noop [anticipatory] deadline cfq

16/* A lot of complication here is taken away because:
17 *
18 * 1) We handle one interrupt and return, sitting in a loop and moving across
19 * all the pending IRQ bits in the cause register is _NOT_ the answer, the
20 * common case is one pending IRQ so optimize in that direction.
21 *
22 * 2) We need not check against bits in the status register IRQ mask, that
23 * would make this routine slow as hell.
24 *
25 * 3) Linux only thinks in terms of all IRQs on or all IRQs off, nothing in
26 * between like BSD spl() brain-damage.
27 *
28 * Furthermore, the IRQs on the INDY look basically (barring software IRQs
29 * which we don't use at all) like:
30 *
31 * MIPS IRQ Source
32 * -------- ------
33 * 0 Software (ignored)
34 * 1 Software (ignored)
35 * 2 Local IRQ level zero
36 * 3 Local IRQ level one
37 * 4 8254 Timer zero
38 * 5 8254 Timer one
39 * 6 Bus Error
40 * 7 R4k timer (what we use)
41 *
42 * We handle the IRQ according to _our_ priority which is:
43 *
44 * Highest ---- R4k Timer
45 * Local IRQ zero
46 * Local IRQ one
47 * Bus Error
48 * 8254 Timer zero
49 * Lowest ---- 8254 Timer one
50 *
51 * then we just return, if multiple IRQs are pending then we will just take
52 * another exception, big deal.

626 * the target IXMT and set a software interrupt, but an IXMT-based

629 * A more gonzo approach within a VPE is to halt the TC, extract
630 * its Restart, Status, and a couple of GPRs, and program the Restart
631 * address to emulate an interrupt.
632 *
633 * Within a VPE, one can be confident that the target TC isn't in
634 * a critical EXL state when halted, since the write to the Halt
635 * register could not have issued on the writing thread if the
636 * halting thread had EXL set. So k0 and k1 of the target TC
637 * can be used by the injection code. Across VPEs, one can't
638 * be certain that the target TC isn't in a critical exception
639 * state. So we try a two-step process of sending a software

46/* A lot of complication here is taken away because:
47 *
48 * 1) We handle one interrupt and return, sitting in a loop and moving across
49 * all the pending IRQ bits in the cause register is _NOT_ the answer, the
50 * common case is one pending IRQ so optimize in that direction.
51 *
52 * 2) We need not check against bits in the status register IRQ mask, that
53 * would make this routine slow as hell.
54 *
55 * 3) Linux only thinks in terms of all IRQs on or all IRQs off, nothing in
56 * between like BSD spl() brain-damage.
57 *
58 * Furthermore, the IRQs on the MIPS board look basically (barring software
59 * IRQs which we don't use at all and all external interrupt sources are
60 * combined together on hardware interrupt 0 (MIPS IRQ 2)) like:
61 *
62 * MIPS IRQ Source
63 * -------- ------
64 * 0 Software (ignored)
65 * 1 Software (ignored)
66 * 2 Combined hardware interrupt (hw0)
67 * 3 Hardware (ignored)
68 * 4 Hardware (ignored)
69 * 5 Hardware (ignored)
70 * 6 Hardware (ignored)
71 * 7 R4k timer (what we use)
72 *
73 * Note: On the SEAD board thing are a little bit different.
74 * Here IRQ 2 (hw0) is wired to the UART0 and IRQ 3 (hw1) is wired
75 * wired to UART1.
76 *
77 * We handle the IRQ according to _our_ priority which is:
78 *
79 * Highest ---- R4k Timer
80 * Lowest ---- Combined hardware interrupt
81 *
82 * then we just return, if multiple IRQs are pending then we will just take
83 * another exception, big deal.

13/* A lot of complication here is taken away because:
14 *
15 * 1) We handle one interrupt and return, sitting in a loop and moving across
16 * all the pending IRQ bits in the cause register is _NOT_ the answer, the
17 * common case is one pending IRQ so optimize in that direction.
18 *
19 * 2) We need not check against bits in the status register IRQ mask, that
20 * would make this routine slow as hell.
21 *
22 * 3) Linux only thinks in terms of all IRQs on or all IRQs off, nothing in
23 * between like BSD spl() brain-damage.
24 *
25 * Furthermore, the IRQs on the INDY look basically (barring software IRQs
26 * which we don't use at all) like:
27 *
28 * MIPS IRQ Source
29 * -------- ------
30 * 0 Software (ignored)
31 * 1 Software (ignored)
32 * 2 Local IRQ level zero
33 * 3 Local IRQ level one
34 * 4 8254 Timer zero
35 * 5 8254 Timer one
36 * 6 Bus Error
37 * 7 R4k timer (what we use)
38 *
39 * We handle the IRQ according to _our_ priority which is:
40 *
41 * Highest ---- R4k Timer

45 * 8254 Timer zero
