-This README escorted the skystar2-driver rewriting procedure. It describes the
-state of the new flexcop-driver set and some internals are written down here
-too.
-
-This document hopefully describes things about the flexcop and its
-device-offsprings. Goal was to write an easy-to-write and easy-to-read set of
-drivers based on the skystar2.c and other information.
-
-Remark: flexcop-pci.c was a copy of skystar2.c, but every line has been
-touched and rewritten.
-
-History & News
-==============
- 2005-04-01 - correct USB ISOC transfers (thanks to Vadim Catana)
-
-
-
-
-General coding processing
-=========================
-
-We should proceed as follows (as long as no one complains):
-
-0) Think before start writing code!
-
-1) rewriting the skystar2.c with the help of the flexcop register descriptions
-and splitting up the files to a pci-bus-part and a flexcop-part.
-The new driver will be called b2c2-flexcop-pci.ko/b2c2-flexcop-usb.ko for the
-device-specific part and b2c2-flexcop.ko for the common flexcop-functions.
-
-2) Search for errors in the leftover of flexcop-pci.c (compare with pluto2.c
-and other pci drivers)
-
-3) make some beautification (see 'Improvements when rewriting (refactoring) is
-done')
-
-4) Testing the new driver and maybe substitute the skystar2.c with it, to reach
-a wider tester audience.
-
-5) creating an usb-bus-part using the already written flexcop code for the pci
-card.
-
-Idea: create a kernel-object for the flexcop and export all important
-functions. This option saves kernel-memory, but maybe a lot of functions have
-to be exported to kernel namespace.
-
-
-Current situation
-=================
-
-0) Done :)
-1) Done (some minor issues left)
-2) Done
-3) Not ready yet, more information is necessary
-4) next to be done (see the table below)
-5) USB driver is working (yes, there are some minor issues)
-
-What seems to be ready?
------------------------
-
-1) Rewriting
-1a) i2c is cut off from the flexcop-pci.c and seems to work
-1b) moved tuner and demod stuff from flexcop-pci.c to flexcop-tuner-fe.c
-1c) moved lnb and diseqc stuff from flexcop-pci.c to flexcop-tuner-fe.c
-1e) eeprom (reading MAC address)
-1d) sram (no dynamic sll size detection (commented out) (using default as JJ told me))
-1f) misc. register accesses for reading parameters (e.g. resetting, revision)
-1g) pid/mac filter (flexcop-hw-filter.c)
-1i) dvb-stuff initialization in flexcop.c (done)
-1h) dma stuff (now just using the size-irq, instead of all-together, to be done)
-1j) remove flexcop initialization from flexcop-pci.c completely (done)
-1l) use a well working dma IRQ method (done, see 'Known bugs and problems and TODO')
-1k) cleanup flexcop-files (remove unused EXPORT_SYMBOLs, make static from
-non-static where possible, moved code to proper places)
-
-2) Search for errors in the leftover of flexcop-pci.c (partially done)
-5a) add MAC address reading
-5c) feeding of ISOC data to the software demux (format of the isochronous data
-and speed optimization, no real error) (thanks to Vadim Catana)
-
-What to do in the near future?
---------------------------------------
-(no special order here)
-
-5) USB driver
-5b) optimize isoc-transfer (submitting/killing isoc URBs when transfer is starting)
-
-Testing changes

-Known bugs and problems and TODO
---------------------------------
-
-1g/h/l) when pid filtering is enabled on the pci card
-
-DMA usage currently:
- The DMA is splitted in 2 equal-sized subbuffers. The Flexcop writes to first
- address and triggers an IRQ when it's full and starts writing to the second
- address. When the second address is full, the IRQ is triggered again, and
- the flexcop writes to first address again, and so on.
- The buffersize of each address is currently 640*188 bytes.
-
- Problem is, when using hw-pid-filtering and doing some low-bandwidth
- operation (like scanning) the buffers won't be filled enough to trigger
- the IRQ. That's why:
-
- When PID filtering is activated, the timer IRQ is used. Every 1.97 ms the IRQ
- is triggered. Is the current write address of DMA1 different to the one
- during the last IRQ, then the data is passed to the demuxer.
-
- There is an additional DMA-IRQ-method: packet count IRQ. This isn't
- implemented correctly yet.
-
- The solution is to disable HW PID filtering, but I don't know how the DVB
- API software demux behaves on slow systems with 45MBit/s TS.
-
-Solved bugs :)
---------------
-1g) pid-filtering (somehow pid index 4 and 5 (EMM_PID and ECM_PID) aren't
-working)
-SOLUTION: also index 0 was affected, because net_translation is done for
-these indexes by default
-
-5b) isochronous transfer does only work in the first attempt (for the Sky2PC
-USB, Air2PC is working) SOLUTION: the flexcop was going asleep and never really
-woke up again (don't know if this need fixes, see
-flexcop-fe-tuner.c:flexcop_sleep)
-
-NEWS: when the driver is loaded and unloaded and loaded again (w/o doing
-anything in the while the driver is loaded the first time), no transfers take
-place anymore.
-
-Improvements when rewriting (refactoring) is done
-=================================================
-
-- split sleeping of the flexcop (misc_204.ACPI3_sig = 1;) from lnb_control
- (enable sleeping for other demods than dvb-s)
-- add support for CableStar (stv0297 Microtune 203x/ALPS) (almost done, incompatibilities with the Nexus-CA)
-
-Debugging
----------
-- add verbose debugging to skystar2.c (dump the reg_dw_data) and compare it
- with this flexcop, this is important, because i2c is now using the
- flexcop_ibi_value union from flexcop-reg.h (do you have a better idea for
- that, please tell us so).
-
-Everything which is identical in the following table, can be put into a common
-flexcop-module.
-
- PCI USB
--------------------------------------------------------------------------------
-Different:
-Register access: accessing IO memory USB control message
-I2C bus: I2C bus of the FC USB control message
-Data transfer: DMA isochronous transfer
-EEPROM transfer: through i2c bus not clear yet
-
-Identical:
-Streaming: accessing registers
-PID Filtering: accessing registers
-Sram destinations: accessing registers
-Tuner/Demod: I2C bus
-DVB-stuff: can be written for common use
-

-
-
-Locking
--------
-
-Each runqueue has its own lock, rq->lock. When multiple runqueues need
-to be locked, lock acquires must be ordered by ascending &runqueue value.
-
-A specific runqueue is locked via
-
- task_rq_lock(task_t pid, unsigned long *flags)
-
-which disables preemption, disables interrupts, and locks the runqueue pid is
-running on. Likewise,
-
- task_rq_unlock(task_t pid, unsigned long *flags)
-
-unlocks the runqueue pid is running on, restores interrupts to their previous
-state, and reenables preemption.
-
-The routines
-
- double_rq_lock(runqueue_t *rq1, runqueue_t *rq2)
-
-and
-
- double_rq_unlock(runqueue_t *rq1, runqueue_t *rq2)
-
-safely lock and unlock, respectively, the two specified runqueues. They do
-not, however, disable and restore interrupts. Users are required to do so
-manually before and after calls.
-
-
-Values
-------
-
-MAX_PRIO
- The maximum priority of the system, stored in the task as task->prio.
- Lower priorities are higher. Normal (non-RT) priorities range from
- MAX_RT_PRIO to (MAX_PRIO - 1).
-MAX_RT_PRIO
- The maximum real-time priority of the system. Valid RT priorities
- range from 0 to (MAX_RT_PRIO - 1).
-MAX_USER_RT_PRIO
- The maximum real-time priority that is exported to user-space. Should
- always be equal to or less than MAX_RT_PRIO. Setting it less allows
- kernel threads to have higher priorities than any user-space task.
-MIN_TIMESLICE
-MAX_TIMESLICE
- Respectively, the minimum and maximum timeslices (quanta) of a process.
-
-Data
-----
-
-struct runqueue
- The main per-CPU runqueue data structure.
-struct task_struct
- The main per-process data structure.
-
-
-General Methods
----------------
-
-cpu_rq(cpu)
- Returns the runqueue of the specified cpu.
-this_rq()
- Returns the runqueue of the current cpu.
-task_rq(pid)
- Returns the runqueue which holds the specified pid.
-cpu_curr(cpu)
- Returns the task currently running on the given cpu.
-rt_task(pid)
- Returns true if pid is real-time, false if not.
-
-
-Process Control Methods
------------------------
-
-void set_user_nice(task_t *p, long nice)
- Sets the "nice" value of task p to the given value.
-int setscheduler(pid_t pid, int policy, struct sched_param *param)
- Sets the scheduling policy and parameters for the given pid.
-int set_cpus_allowed(task_t *p, unsigned long new_mask)
- Sets a given task's CPU affinity and migrates it to a proper cpu.
- Callers must have a valid reference to the task and assure the
- task not exit prematurely. No locks can be held during the call.
-set_task_state(tsk, state_value)
- Sets the given task's state to the given value.
-set_current_state(state_value)
- Sets the current task's state to the given value.
-void set_tsk_need_resched(struct task_struct *tsk)
- Sets need_resched in the given task.
-void clear_tsk_need_resched(struct task_struct *tsk)
- Clears need_resched in the given task.
-void set_need_resched()
- Sets need_resched in the current task.
-void clear_need_resched()
- Clears need_resched in the current task.
-int need_resched()
- Returns true if need_resched is set in the current task, false
- otherwise.
-yield()
- Place the current process at the end of the runqueue and call schedule.

+ * CONFIG_LATENCYTOP enables a kernel latency tracking infrastructure that is
+ * used by the "latencytop" userspace tool. The latency that is tracked is not
+ * the 'traditional' interrupt latency (which is primarily caused by something
+ * else consuming CPU), but instead, it is the latency an application encounters
+ * because the kernel sleeps on its behalf for various reasons.
+ *
+ * This code tracks 2 levels of statistics:
+ * 1) System level latency
+ * 2) Per process latency
+ *
+ * The latency is stored in fixed sized data structures in an accumulated form;
+ * if the "same" latency cause is hit twice, this will be tracked as one entry
+ * in the data structure. Both the count, total accumulated latency and maximum
+ * latency are tracked in this data structure. When the fixed size structure is
+ * full, no new causes are tracked until the buffer is flushed by writing to
+ * the /proc file; the userspace tool does this on a regular basis.
+ *
+ * A latency cause is identified by a stringified backtrace at the point that
+ * the scheduler gets invoked. The userland tool will use this string to
+ * identify the cause of the latency in human readable form.
+ *
+ * The information is exported via /proc/latency_stats and /proc/<pid>/latency.
+ * These files look like this:
+ *
+ * Latency Top version : v0.1
+ * 70 59433 4897 i915_irq_wait drm_ioctl vfs_ioctl do_vfs_ioctl sys_ioctl

+ * | | +---------> The maximum latency for this entry in microseconds
+ * | +--------------> The accumulated latency for this entry (microseconds)
+ * +-------------------> The number of times this entry is hit

+ * (note: the average latency is the accumulated latency divided by the number
+ * of times)
