+
+IrDA Cache last LSAP
+CONFIG_IRDA_CACHE_LAST_LSAP
+ Say Y here if you want IrLMP to cache the last LSAP used. This makes
+ sense since most frames will be sent/received on the same connection.
+ Enabling this option will save a hash-lookup per frame.
+
+ If unsure, say Y.
+
+IrDA Fast RR's
+CONFIG_IRDA_FAST_RR
+ Say Y here is you want IrLAP to send fast RR (Receive Ready) frames
+ when acting as a primary station. This will make IrLAP send out a RR
+ frame immediately when receiving a frame if its own transmit queue is
+ currently empty. This will give a lot of speed improvement when
+ receiving much data since the secondary station will not have to
+ wait the max. turn around time before it is allowed to transmit the
+ next time. If the transmit queue of the secondary is also empty the
+ primary will back off waiting longer for sending out the RR frame
+ until the timeout reaches the normal value. Enabling this option
+ will make the IR-diode burn more power and thus reduce your battery
+ life.
+
+ If unsure, say N.
+
+IrDA Recycle RR's
+CONFIG_IRDA_RECYCLE_RR
+ In the normal life of the IrLAP protocol, it sends a lot of small RR
+ (Receive Ready) frames over the link (at least when it has nothing
+ else to do). Saying Y to this option will make IrLAP recycle these
+ frames thus avoiding many alloc_skb's and kfree_skb's. To do this it
+ will only buffer one of these frame which is enough for the normal
+ case.
+
+ If unsure, say Y.
+
+IrLAP Compression support
+CONFIG_IRDA_COMPRESSION
+ Compression is _not_ part of the IrDA(tm) protocol specification,
+ but its working great! Linux is the first to try out compresson
+ support at the IrLAP layer. This means that you will only benefit
+ from compression if you are running a Linux <-> Linux configuration

+CONFIG_IRDA_DEFLATE
+ Say Y here if you want to build support for the Deflate compression
+ protocol. If you want to compile it as a module, say M here and read

+
+IrLAN Server Protocol
+CONFIG_IRLAN_SERVER
+ Say Y here if you want to build support for infrared LAN access. If
+ you want to compile it as a module, say M here and read
+ Documentation/modules.txt. The IrLAN server protocol makes it
+ possible to set up a wireless LAN with a machine running the IrLAN
+ client protocol. Notice that the IrLAN server protocol currently
+ only emulates an access point and does not implement the ad-hoc
+ specification of IrLAN, but this will not be noticeable for the
+ user.
+
+IrOBEX Protocol
+CONFIG_IROBEX
+ Say Y here if you want to build support for the IrOBEX protocol. If
+ you want to compile it as a module, say M here and read
+ Documentation/modules.txt. The module does not actually implement
+ the IrOBEX protocol since that protocol lives in userspace, but it
+ contains the necessary functions to interface the user-space stuff
+ with the kernel. So you will need to have the user-space library and
+ programs that can use this library installed as well to be able to
+ use the IrOBEX protocol. This module will hopefully be replaced by
+ IrDA sockets in the future.
+
+IrCOMM Protocol
+CONFIG_IRCOMM
+ Say Y here if you want to build support for the IrCOMM protocol. If
+ you want to compile it as a module, say M here and read
+ Documentation/modules.txt. IrCOMM implements serial port emulation,
+ and makes it possible to use all existing applications that
+ understands TTY's with an infrared link. Thus you should be able to
+ use application like PPP, minicom and others. Enabling this option
+ will create two modules called ircomm and ircomm_tty. For more

+IrTTY IrDA Device Driver
+CONFIG_IRTTY_SIR
+ Say Y here if you want to build support for the IrTTY line
+ discipline. If you want to compile it as a module, say M here and
+ read Documentation/modules.txt. IrTTY makes it possible to use
+ Linux's own serial driver for all IrDA ports that are 16550
+ compatible. Most IrDA chips are 16550 compatible so you should
+ probably say Y to this option. Using IrTTY will however limit the

+Tekram IrMate 210B dongle
+CONFIG_TEKRAM_DONGLE
+ Say Y here if you want to build support for the Tekram IrMate 210B
+ dongle. If you want to compile it as a module, say M here

+
+VME (Motorola and BVM) support
+CONFIG_VME
+ Say Y here if you want to build a kernel for a 680x0 based VME
+ board. Boards currently supported include Motorola boards MVME162,
+ MVME166, MVME167, MVME172, and MVME177. BVME4000 and BVME6000
+ boards from BVM Ltd are also supported.
+
+MVME162, 166 and 167 support
+CONFIG_MVME16x
+ Say Y to include support for Motorola VME boards. This will build a
+ kernel which can run on MVME162, MVME166, MVME167, MVME172, and

+
+Use write-through caching for 68060 supervisor accesses
+CONFIG_060_WRITETHROUGH
+ The 68060 generally uses copyback caching of recently accessed data.
+ Copyback caching means that memory writes will be held in an on-chip
+ cache and only written back to memory some time later. Saying Y
+ here will force supervisor (kernel) accesses to use writethrough
+ caching. Writethrough caching means that data is written to memory
+ straight away, so that cache and memory data always agree.
+ Writethrough caching is less efficient, but is needed for some
+ drivers on 68060 based systems where the 68060 bus snooping signal
+ is hardwired on. The 53c710 SCSI driver is known to suffer from
+ this problem.
+
+NCR53C710 SCSI driver for MVME16x
+CONFIG_MVME16x_SCSI
+ The Motorola MVME162, 166, 167, 172 and 177 boards use the NCR53C710

- * INET An implementation of the TCP/IP protocol suite for the LINUX

- * IP/TCP/UDP checksumming routines
- *
- * Authors: Jorge Cwik, <jorge@laser.satlink.net>

- * Tom May, <ftom@netcom.com>
- * Pentium Pro/II routines:

- * Finn Arne Gangstad <finnag@guardian.no>
- * Lots of code moved from tcp.c and ip.c; see those files
- * for more names.
- *
- * Changes: Ingo Molnar, converted csum_partial_copy() to 2.1 exception
- * handling.
- * Andi Kleen, add zeroing on error, fix constraints.
- *
- * To fix:
- * Convert to pure asm, because this file is too hard

* This will allow us to get automagically notified when the media changes
* on ATAPI drives (something the stock ATAPI spec is lacking). Looks
* very cool. I discovered its existance the other day at work...
- * -Fix ide_cdrom_reset so that it works (it does nothing right now)
* -Query the drive to find what features are available before trying to
* use them (like trying to close the tray in drives that can't).
* -Make it so that Pioneer CD DR-A24X and friends don't get screwed up on
* -Handle older drives that can't report their speed. (i.e. check if they
* support a version of ATAPI where they can report their speed before
* checking their speed and believing what they return).
- * -It seems we do not always honor it when Uniform gets a request to change
- * the cdi->options. We should _always_ check the options before doing stuff.
- * This must be fixed.

the next revisions will be 2.0a to 2.0X (stable), 2.1a to 2.1X (experimental),

compiling.
-If you got an older kernel with an old version of this driver included, you

-You should apply the three patches included in dc390-20-kernel.diff
-(Applying them: cd /usr/src; patch -p0 <~/dc390-20-kernel.diff)

If you got a very old kernel without the tmscsim driver (pre 2.0.31)
I recommend upgrading your kernel. However, if you don't want to, please
contact me to get the appropriate patches.

3.Features
----------
- SCSI
- * Tagged queueing
+ * Tagged command queueing
* Sync speed up to 10 MHz
* Disconnection
* Multiple LUNs
- General / Linux interface
- * Support for up to 4 adapters.
+ * Support for up to 4 AM53C974 adapters.
* DC390 EEPROM usage or boot/module params
* Information via cat /proc/scsi/tmscsim/?
* Dynamically configurable by writing to /proc/scsi/tmscsim/?
* Dynamic allocation of resources
- * SMP support: Adapter specific locks (Linux 2.1.x)
+ * SMP support: Locking on io_request lock (Linux 2.1/2.2) or adapter
+ specific locks (Linux 2.3)
* Uniform source code for Linux-2.x.y
* Support for dyn. addition/removal of devices via add/remove-single-device
(Try: echo "scsi add-single-device H C I L" >/proc/scsi/scsi
Further investigation on these problems:
-* TagQ and Disconnection (Resel: SRB Tag Seleection)
-* Problems with IRQ sharing (IO-APIC on SMP Systems) (??)
-* Driver crashes with readcdda (xcdroast)
+* Driver hangs with sync readcdda (xcdroast) (most probably VIA PCI error)
Known problems:
Richard Waltham <dormouse@farsrobt.demon.co.uk> or Doug Ledford
<dledford@dialnet.net>, if you want to help further debugging it.
* 2.0.35: CD changers (e.g. NAKAMICHI MBR-7.{0,2}) have problems because
- the mid-level code doesn't handle BLIST_SINGLELUN correctly. Apply
- the patch 2035-scsi-singlelun.diff. Thanks to Chiaki Ishikawa.
- I was told that this fix will be in 2.0.36, so you don't need it for
- 2.0.36.
-[The patch file is contained in the dc390-XXX.tar.gz files which can be found
-on the ftp server. See below.]
+ the mid-level code doesn't handle BLIST_SINGLELUN correctly. There used

7. Bug reports, debugging and updates
Please append the output of /proc/scsi/scsi, /proc/scsi/tmscsim/? and
maybe the DC390 log messages to the report.
-Bug reports should be send to me (Kurt Garloff <K.Garloff@ping.de>) as well
+Bug reports should be send to me (Kurt Garloff <dc390@garloff.de>) as well
as to the linux-scsi list (<linux-scsi@vger.rutgers.edu>), as sometimes bugs
are caused by the SCSI mid-level code.

+ *
+ * Further notes on refinement (Christoph Rohland, December 1998):
+ * - The POSIX standard says, that the undo adjustments simply should
+ * redo. So the current implementation is o.K.
+ * - The previous code had two flaws:
+ * 1) It actively gave the semaphore to the next waiting process
+ * sleeping on the semaphore. Since this process did not have the
+ * cpu this led to many unnecessary context switches and bad
+ * performance. Now we only check which process should be able to
+ * get the semaphore and if this process wants to reduce some
+ * semaphore value we simply wake it up without doing the
+ * operation. So it has to try to get it later. Thus e.g. the
+ * running process may reaquire the semaphore during the current
+ * time slice. If it only waits for zero or increases the semaphore,
+ * we do the operation in advance and wake it up.
+ * 2) It did not wake up all zero waiting processes. We try to do
+ * better but only get the semops right which only wait for zero or
+ * increase. If there are decrement operations in the operations
+ * array we do the same as before.
