+This is a short introduction to the coding style that shall be used. The below
+rules are applicable for all C source files, except the Ethernet drivers, for
+which the Linux Kernel coding style shall be used to minimize the
+differences).
+
+* Lines shall not exceed 78 characters.
+
+* Indentation shall be done using 4 space characters
+
+* No whitespace shall be left at the end of a line.
+
+* After a comma, a single space shall be placed (if not followed by a
+ line break).
+
+* Braces shall be placed in the following way (K&R style):
+
+ if (...) {
+ ...
+ } else if (...) {
+ ...
+ } else {
+ ...
+ }
+
+ int function(...)
+ {
+ ...
+ }
+
+* Macros shall be named in CAPITAL letters. If a macro contains multiple
+ statements, they should be enclosed by a 'do {} while (0)' loop. Macro
+ parameters shall also be capital letters and shall be enclosed py parantheses
+ if necessary.
+
+ #define MACRO(A, B) \
+ do { \
+ if ((A) == 1) { \
+ statement(B); \
+ } while (0)

Realtime patches for the Linux kernel are supported, but not required. The

To avoid frame timeouts, deactivating DMA access for hard drives is
recommended (hdparm -d0 <DEV>).
