+ *      Hardware SPP (a.k.a. compatibility), EPP, and ECP modes are

+ *      SPP/ECP FIFO can be driven in PIO or DMA mode.  PIO mode can work with
+ *      or without interrupt support.
+ *
+ *      Hardware ECP mode is not fully implemented (ecp_read_data and
+ *      ecp_write_addr are actually missing).
+ *
+ * To do:
+ *
+ *      Fully implement ECP mode.
+ *      EPP and ECP mode need to be tested.  I currently do not own any
+ *      peripheral supporting these extended mode, and cannot test them.
+ *      If DMA mode works well, decide if support for PIO FIFO modes should be
+ *      dropped.
+ *      Use the io{read,write} family functions when they become available in
+ *      the linux-mips.org tree.  Note: the MIPS specific functions readsb()
+ *      and writesb() are to be translated by ioread8_rep() and iowrite8_rep()

+/*
+ * The internal buffer is meant to store obaque blobs of data, so it doesn't
+ * know of higher level concepts like triggers.
+ * It consists of a number of pages that are used as a ringbuffer. Each data
+ * blob is stored in a simple record that consists of an integer, which
+ * contains the size of the following data, and the data bytes themselfes.
+ *
+ * To allow for multiple independent readers we create one internal buffer
+ * each time the device is opened and destroy the buffer when the file is
+ * closed again.
+ *
+ * One record can be written to a buffer by using the functions
+ * - dasd_eer_start_record (one time per record to write the size to the buffer
+ *                          and reserve the space for the data)
+ * - dasd_eer_write_buffer (one or more times per record to write the data)
+ * The data can be written in several steps but you will have to compute
+ * the total size up front for the invocation of dasd_eer_start_record.
+ * If the ringbuffer is full, dasd_eer_start_record will remove the required
+ * number of old records.
+ *
+ * A record is typically read in two steps, first read the integer that
+ * specifies the size of the following data, then read the data.
+ * Both can be done by
+ * - dasd_eer_read_buffer
+ *
+ * For all mentioned functions you need to get the bufferlock first and keep it
+ * until a complete record is written or read.
+ */
+
+
+/*
+ * Alle information necessary to keep track of an internal buffer is kept in
+ * a struct eerbuffer. The buffer specific to a file pointer is strored in
+ * the private_data field of that file. To be able to write data to all
+ * existing buffers, each buffer is also added to the bufferlist.
+ * If the user doesn't want to read a complete record in one go, we have to
+ * keep track of the rest of the record. residual stores the number of bytes
+ * that are still to deliver. If the rest of the record is invalidated between
+ * two reads then residual will be set to -1 so that the next read will fail.
+ * All entries in the eerbuffer structure are protected with the bufferlock.
+ * To avoid races between writing to a buffer on the one side and creating
+ * and destroying buffers on the other side, the bufferlock must also be used
+ * to protect the bufferlist.

+ * When a DASD device driver wants to report an error, it calls the
+ * function dasd_eer_write_trigger (via a notifier mechanism) and gives the
+ * respective trigger ID as parameter.
+ * Currently there are four kinds of triggers:
+ *
+ * DASD_EER_FATALERROR:  all kinds of unrecoverable I/O problems
+ * DASD_EER_PPRCSUSPEND: PPRC was suspended
+ * DASD_EER_NOPATH:      There is no path to the device left.
+ * DASD_EER_STATECHANGE: The state of the device has changed.
+ *
+ * For the first three triggers all required information can be supplied by
+ * the caller. For these triggers a record is written by the function
+ * dasd_eer_write_standard_trigger.
+ *
+ * When dasd_eer_write_trigger is called to write a DASD_EER_STATECHANGE
+ * trigger, we have to gather the necessary sense data first. We cannot queue
+ * the necessary SNSS (sense subsystem status) request immediatly, since we
+ * are likely to run in a deadlock situation. Instead, we schedule a
+ * work_struct that calls the function dasd_eer_sense_subsystem_status to
+ * create and start an SNSS  request asynchronously.
+ *
+ * To avoid memory allocations at runtime, the necessary memory is allocated
+ * when the extended error reporting is enabled for a device (by
+ * dasd_eer_probe). There is one private eer data structure for each eer
+ * enabled DASD device. It contains memory for the work_struct, one SNSS cqr
+ * and a flags field that is used to coordinate the use of the cqr. The call
+ * to write a state change trigger can come in at any time, so we have one flag
+ * CQR_IN_USE that protects the cqr itself. When this flag indicates that the
+ * cqr is currently in use, dasd_eer_sense_subsystem_status cannot start a
+ * second request but sets the SNSS_REQUESTED flag instead.
+ *
+ * When the request is finished, the callback function dasd_eer_SNSS_cb
+ * is called. This function will invoke the function
+ * dasd_eer_write_SNSS_trigger to finally write the trigger. It will also
+ * check the SNSS_REQUESTED flag and if it is set it will call
+ * dasd_eer_sense_subsystem_status again.
+ *
+ * To avoid race conditions during the handling of the lock, the flags must
+ * be protected by the snsslock.
