- <title>Driver Compatibility</title>
-
-<para>
-This device driver is designed for the DECchip "Tulip", Digital's
-single-chip ethernet controllers for PCI (now owned by Intel).
-Supported members of the family
-are the 21040, 21041, 21140, 21140A, 21142, and 21143. Similar work-alike
-chips from Lite-On, Macronics, ASIX, Compex and other listed below are also
-supported.
-</para>
-
-<para>
-These chips are used on at least 140 unique PCI board designs. The great
-number of chips and board designs supported is the reason for the
-driver size and complexity. Almost of the increasing complexity is in the
-board configuration and media selection code. There is very little
-increasing in the operational critical path length.
-</para>
- </chapter>
-
- <chapter id="board-settings">
- <title>Board-specific Settings</title>
-
-<para>
-PCI bus devices are configured by the system at boot time, so no jumpers
-need to be set on the board. The system BIOS preferably should assign the
-PCI INTA signal to an otherwise unused system IRQ line.
-</para>
-
-<para>
-Some boards have EEPROMs tables with default media entry. The factory default
-is usually "autoselect". This should only be overridden when using
-transceiver connections without link beat e.g. 10base2 or AUI, or (rarely!)
-for forcing full-duplex when used with old link partners that do not do
-autonegotiation.
-</para>
- </chapter>

- <title>Driver Operation</title>
-
-<sect1><title>Ring buffers</title>
-
-<para>
-The Tulip can use either ring buffers or lists of Tx and Rx descriptors.
-This driver uses statically allocated rings of Rx and Tx descriptors, set at
-compile time by RX/TX_RING_SIZE. This version of the driver allocates skbuffs
-for the Rx ring buffers at open() time and passes the skb->data field to the
-Tulip as receive data buffers. When an incoming frame is less than
-RX_COPYBREAK bytes long, a fresh skbuff is allocated and the frame is
-copied to the new skbuff. When the incoming frame is larger, the skbuff is
-passed directly up the protocol stack and replaced by a newly allocated
-skbuff.
-</para>
-
-<para>
-The RX_COPYBREAK value is chosen to trade-off the memory wasted by
-using a full-sized skbuff for small frames vs. the copying costs of larger
-frames. For small frames the copying cost is negligible (esp. considering
-that we are pre-loading the cache with immediately useful header
-information). For large frames the copying cost is non-trivial, and the
-larger copy might flush the cache of useful data. A subtle aspect of this
-choice is that the Tulip only receives into longword aligned buffers, thus
-the IP header at offset 14 isn't longword aligned for further processing.
-Copied frames are put into the new skbuff at an offset of "+2", thus copying
-has the beneficial effect of aligning the IP header and preloading the
-cache.
-</para>
-
-</sect1>
-
-<sect1><title>Synchronization</title>
-<para>
-The driver runs as two independent, single-threaded flows of control. One
-is the send-packet routine, which enforces single-threaded use by the
-dev->tbusy flag. The other thread is the interrupt handler, which is single
-threaded by the hardware and other software.
-</para>
-
-<para>
-The send packet thread has partial control over the Tx ring and 'dev->tbusy'
-flag. It sets the tbusy flag whenever it's queuing a Tx packet. If the next
-queue slot is empty, it clears the tbusy flag when finished otherwise it sets
-the 'tp->tx_full' flag.
-</para>
-
-<para>
-The interrupt handler has exclusive control over the Rx ring and records stats
-from the Tx ring. (The Tx-done interrupt can't be selectively turned off, so
-we can't avoid the interrupt overhead by having the Tx routine reap the Tx
-stats.) After reaping the stats, it marks the queue entry as empty by setting
-the 'base' to zero. Iff the 'tp->tx_full' flag is set, it clears both the
-tx_full and tbusy flags.
-</para>

- <title>Errata</title>
-
-<para>
-The old DEC databooks were light on details.
-The 21040 databook claims that CSR13, CSR14, and CSR15 should each be the last
-register of the set CSR12-15 written. Hmmm, now how is that possible?
-</para>
-
-<para>
-The DEC SROM format is very badly designed not precisely defined, leading to
-part of the media selection junkheap below. Some boards do not have EEPROM
-media tables and need to be patched up. Worse, other boards use the DEC
-design kit media table when it isn't correct for their board.
-</para>
-
-<para>
-We cannot use MII interrupts because there is no defined GPIO pin to attach
-them. The MII transceiver status is polled using an kernel timer.

+ * User helpers.
+ *
+ * These are segment of kernel provided user code reachable from user space
+ * at a fixed address in kernel memory. This is used to provide user space
+ * with some operations which require kernel help because of unimplemented
+ * native feature and/or instructions in many ARM CPUs. The idea is for
+ * this code to be executed directly in user mode for best efficiency but
+ * which is too intimate with the kernel counter part to be left to user
+ * libraries. In fact this code might even differ from one CPU to another
+ * depending on the available instruction set and restrictions like on
+ * SMP systems. In other words, the kernel reserves the right to change
+ * this code as needed without warning. Only the entry points and their
+ * results are guaranteed to be stable.
+ *
+ * Each segment is 32-byte aligned and will be moved to the top of the high
+ * vector page. New segments (if ever needed) must be added in front of
+ * existing ones. This mechanism should be used only for things that are
+ * really small and justified, and not be abused freely.
+ *
+ * User space is expected to implement those things inline when optimizing
+ * for a processor that has the necessary native support, but only if such
+ * resulting binaries are already to be incompatible with earlier ARM
+ * processors due to the use of unsupported instructions other than what
+ * is provided here. In other words don't make binaries unable to run on
+ * earlier processors just for the sake of not using these kernel helpers
+ * if your compiled code is not going to use the new instructions for other
