212Description:
213 A raw device name of a disk does not always point a same disk
214 each boot-up time. Therefore, users have to use persistent
215 device names, which udev creates when the kernel finds a disk,
216 instead of raw device name. However, kernel doesn't show those
217 persistent names on its messages (e.g. dmesg).
218 This file can store an alias of the disk and it would be
219 appeared in kernel messages if it is set. A disk can have an
220 alias which length is up to 255bytes. Users can use alphabets,
221 numbers, "-" and "_" in alias name. This file is writeonce.

8 * 11/07/96: rewritten interrupt handling, irq lists are exists now only for

10 * be careful that dev_id for this sources is unique since this the
11 * only possibility to distinguish between different handlers for
12 * free_irq. irq lists also have different irq flags:
13 * - IRQ_FLG_FAST: handler is inserted at top of list (after other
14 * fast handlers)
15 * - IRQ_FLG_SLOW: handler is inserted at bottom of list and before
16 * they're executed irq level is set to the previous
17 * one, but handlers don't need to be reentrant, if

24 * interrupts, normal and fast handlers, fast handlers being
25 * marked with IRQF_DISABLED and runs with all other interrupts
26 * disabled. Normal interrupts disable their own source but
27 * run with all other interrupt sources enabled.

64 * Each interrupt can be of three types:
65 *
66 * - SLOW: The handler runs with all interrupts enabled, except the one it
67 * was called by (to avoid reentering). This should be the usual method.
68 * But it is currently possible only for MFP ints, since only the MFP
69 * offers an easy way to mask interrupts.
70 *
71 * - FAST: The handler runs with all interrupts disabled. This should be used
72 * only for really fast handlers, that just do actions immediately
73 * necessary, and let the rest do a bottom half or task queue.
74 *
75 * - PRIORITIZED: The handler can be interrupted by higher-level ints
76 * (greater IPL, no MFP priorities!). This is the method of choice for ints
77 * which should be slow, but are not from a MFP.
78 *
79 * The feature of more than one handler for one int source is still there, but

81 * processing of ints with only one handler by the chaining feature, the list
82 * calling function atari_call_irq_list() is only plugged in at the time the
83 * second handler is registered.
84 *
85 * Implementation notes: For fast-as-possible int handling, there are separate
86 * entry points for each type (slow/fast/prio). The assembler handler calls
87 * the irq directly in the usual case, no C wrapper is involved. In case of
88 * multiple handlers, atari_call_irq_list() is registered as handler and calls
89 * in turn the real irq's. To ease access from assembler level to the irq
90 * function pointer and accompanying data, these two are stored in a separate
91 * array, irq_handler[]. The rest of data (type, name) are put into a second
92 * array, irq_param, that is accessed from C only. For each slow interrupt (32
93 * in all) there are separate handler functions, which makes it possible to
94 * hard-code the MFP register address and value, are necessary to mask the
95 * int. If there'd be only one generic function, lots of calculations would be
96 * needed to determine MFP register and int mask from the vector number :-(
97 *
98 * Furthermore, slow ints may not lower the IPL below its previous value
99 * (before the int happened). This is needed so that an int of class PRIO, on
100 * that this int may be stacked, cannot be reentered. This feature is
101 * implemented as follows: If the stack frame format is 1 (throwaway), the int
102 * is not stacked, and the IPL is anded with 0xfbff, resulting in a new level
103 * 2, which still blocks the HSYNC, but no interrupts of interest. If the
104 * frame format is 0, the int is nested, and the old IPL value can be found in
105 * the sr copy in the frame.

14 * 11/07/96: Changed all add_/remove_isr() to request_/free_irq() calls.
15 * Removed irq list support, if any machine needs an irq server
16 * it must implement this itself (as it's already done), instead
17 * only default handler are used with mach_default_handler.
18 * request_irq got some flags different from other architectures:
19 * - IRQ_FLG_REPLACE : Replace an existing handler (the default one
20 * can be replaced without this flag)
21 * - IRQ_FLG_LOCK : handler can't be replaced
22 * There are other machine depending flags, see there

174# to config variables will be seen by top level config files. Including
175# a file is processed just like the contents of the file was cut and pasted
176# into the top level file, except, that include files that end with
177# TEST_START sections will have that section ended at the end of
178# the include file. That is, an included file is included followed
179# by another DEFAULT keyword.
180#
181# Unlike other files referenced in this config, the file path does not need
182# to be absolute. If the file does not start with '/', then the directory
183# that the current config file was located in is used. If no config by the
184# given name is found there, then the current directory is searched.
185#
186# INCLUDE myfile
187# DEFAULT
188#
189# is the same as:

191# INCLUDE myfile
192#
193# Note, if the include file does not contain a full path, the file is
194# searched first by the location of the original include file, and then
195# by the location that ktest.pl was executed in.
