- * Major Caveats for using FIQ
- * ---------------------------
- *
- * 1) it CANNOT touch any vmalloc()'d memory, only memory
- * that was kmalloc()'d. Static allocations in the monolithic kernel
- * are kmalloc()'d so they are okay. You can touch memory-mapped IO, but
- * the pointer for it has to have been stored in kmalloc'd memory. The
- * reason for this is simple: every now and then Linux turns off interrupts
- * and reorders the paging tables. If a FIQ happens during this time, the
- * virtual memory space can be partly or entirely disordered or missing.
- *
- * 2) Because vmalloc() is used when a module is inserted, THIS FIQ
- * ISR HAS TO BE IN THE MONOLITHIC KERNEL, not a module. But the way
- * it is set up, you can all to enable and disable it from your module
- * and intercommunicate with it through struct fiq_ipc
- * fiq_ipc which you can define in
- * asm/archfiq_ipc_type.h. The reason is the same as above, a
- * FIQ could happen while even the ISR is not present in virtual memory
- * space due to pagetables being changed at the time.
- *
- * 3) You can't call any Linux API code except simple macros
- * - understand that FIQ can come in at any time, no matter what
- * state of undress the kernel may privately be in, thinking it
- * locked the door by turning off interrupts... FIQ is an
- * unstoppable monster force (which is its value)
- * - they are not vmalloc()'d memory safe
- * - they might do crazy stuff like sleep: FIQ pisses fire and
- * is not interested in 'sleep' that the weak seem to need
- * - calling APIs from FIQ can re-enter un-renterable things
- * - summary: you cannot interoperate with linux APIs directly in the FIQ ISR
- *
- * If you follow these rules, it is fantastic, an extremely powerful, solid,
- * genuine hard realtime feature.
