[PATCH 1/2] move host drivers for VLB IDE controllers to staging/out

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Bartlomiej Zolnierkiewicz <bzolnier@xxxxxxxxx>
Subject: [PATCH] move host drivers for VLB IDE controllers to staging/out

- they are for really old hardware that nobody has any longer
- they all require 'magic' parameters to work
- many controllers are also supported by pata_legacy driver

so move them to staging/out and schedule for removal in 2.6.36
unless somebody steps in to work on them.

- * ALI M14xx chipset EIDE controller

- * Adapted from code developed by derekn@xxxxxxxxxxxxxxx  -ml
- * Derek's notes follow:
- *
- * I think the code should be pretty understandable,

- *
- * The critical part is in the setupDrive function.  The initRegisters
- * function doesn't seem to be necessary, but the DOS driver does it, so
- * I threw it in.
- *
- * I've only tested this on my system, which only has one disk.  I posted

- * out.

- * Update 96-jul-13:
- *
- * I've since upgraded to two disks and a CD-ROM, with no trouble, and
- * I've also heard from several others who have used it successfully.
- * This driver appears to work with both the 1443/1445 and the 1487/1489
- * chipsets.  I've added support for PIO mode 4 for the 1487.  This
- * seems to work just fine on the 1443 also, although I'm not sure it's
- * advertised as supporting mode 4.  (I've been running a WDC AC21200 in

- * From: andy@xxxxxxxxxxxxxx (Dyan Wile)
- *
- * Below is a patch for DTC-2278 - alike software-programmable controllers
- * The code enables the secondary IDE controller and the PIO4 (3?) timings on
- * the primary (EIDE). You may probably have to enable the 32-bit support to
- * get the full speed. You better get the disk interrupts disabled ( hdparm -u0
- * /dev/hd.. ) for the drives connected to the EIDE interface. (I get my
- * filesystem  corrupted with -u1, but under heavy disk load only :-)
- *
- * This card is now forced to use the "serialize" feature,
- * and irq-unmasking is disallowed.  If io_32bit is enabled,
- * it must be done for BOTH drives on each interface.
- *
- * This code was written for the DTC2278E, but might work with any of these:
- *
- * DTC2278S has only a single IDE interface.
- * DTC2278D has two IDE interfaces and is otherwise identical to the S version.
- * DTC2278E also has serial ports and a printer port
- * DTC2278EB: has onboard BIOS, and "works like a charm" -- Kent Bradford <kent@xxxxxxxxxxxxxxxxxx>
- *
- * There may be a fourth controller type. The S and D versions use the
- * Winbond chip, and I think the E version does also.

- * ht6560b Timing values:
- *
- * I reviewed some assembler source listings of htide drivers and found
- * out how they setup those cycle time interfacing values, as they at Holtek
- * call them. IDESETUP.COM that is supplied with the drivers figures out
- * optimal values and fetches those values to drivers. I found out that
- * they use Select register to fetch timings to the ide board right after
- * interface switching. After that it was quite easy to add code to
- * ht6560b.c.
- *
- * IDESETUP.COM gave me values 0x24, 0x45, 0xaa, 0xff that worked fine
- * for hda and hdc. But hdb needed higher values to work, so I guess
- * that sometimes it is necessary to give higher value than IDESETUP
- * gives.   [see cmd640.c for an extreme example of this. -ml]
- *
- * Perhaps I should explain something about these timing values:
- * The higher nibble of value is the Recovery Time  (rt) and the lower nibble
- * of the value is the Active Time  (at). Minimum value 2 is the fastest and
- * the maximum value 15 is the slowest. Default values should be 15 for both.
- * So 0x24 means 2 for rt and 4 for at. Each of the drives should have
- * both values, and IDESETUP gives automatically rt=15 st=15 for CDROMs or
- * similar. If value is too small there will be all sorts of failures.
- *
- * Timing byte consists of
- *	High nibble:  Recovery Cycle Time  (rt)
- *	     The valid values range from 2 to 15. The default is 15.
- *
- *	Low nibble:   Active Cycle Time	   (at)
- *	     The valid values range from 2 to 15. The default is 15.
- *
- * You can obtain optimized timing values by running Holtek IDESETUP.COM
- * for DOS. DOS drivers get their timing values from command line, where
- * the first value is the Recovery Time and the second value is the
- * Active Time for each drive. Smaller value gives higher speed.
- * In case of failures you should probably fall back to a higher value.

+ * The code enables the secondary IDE controller and the PIO4 (3?) timings on
+ * the primary (EIDE). You may probably have to enable the 32-bit support to
+ * get the full speed. You better get the disk interrupts disabled ( hdparm -u0
+ * /dev/hd.. ) for the drives connected to the EIDE interface. (I get my

+ *
+ * This card is now forced to use the "serialize" feature,
+ * and irq-unmasking is disallowed.  If io_32bit is enabled,
+ * it must be done for BOTH drives on each interface.
+ *
+ * This code was written for the DTC2278E, but might work with any of these:
+ *
+ * DTC2278S has only a single IDE interface.
+ * DTC2278D has two IDE interfaces and is otherwise identical to the S version.
+ * DTC2278E also has serial ports and a printer port
+ * DTC2278EB: has onboard BIOS, and "works like a charm" -- Kent Bradford <kent@xxxxxxxxxxxxxxxxxx>

+ * There may be a fourth controller type. The S and D versions use the

+ * ht6560b Timing values:
+ *
+ * I reviewed some assembler source listings of htide drivers and found
+ * out how they setup those cycle time interfacing values, as they at Holtek
+ * call them. IDESETUP.COM that is supplied with the drivers figures out
+ * optimal values and fetches those values to drivers. I found out that
+ * they use Select register to fetch timings to the ide board right after
+ * interface switching. After that it was quite easy to add code to
+ * ht6560b.c.
+ *
+ * IDESETUP.COM gave me values 0x24, 0x45, 0xaa, 0xff that worked fine
+ * for hda and hdc. But hdb needed higher values to work, so I guess
+ * that sometimes it is necessary to give higher value than IDESETUP
+ * gives.   [see cmd640.c for an extreme example of this. -ml]
+ *
+ * Perhaps I should explain something about these timing values:
+ * The higher nibble of value is the Recovery Time  (rt) and the lower nibble
+ * of the value is the Active Time  (at). Minimum value 2 is the fastest and
+ * the maximum value 15 is the slowest. Default values should be 15 for both.
+ * So 0x24 means 2 for rt and 4 for at. Each of the drives should have
+ * both values, and IDESETUP gives automatically rt=15 st=15 for CDROMs or
+ * similar. If value is too small there will be all sorts of failures.
+ *
+ * Timing byte consists of
+ *	High nibble:  Recovery Cycle Time  (rt)
+ *	     The valid values range from 2 to 15. The default is 15.
+ *
+ *	Low nibble:   Active Cycle Time	   (at)
+ *	     The valid values range from 2 to 15. The default is 15.
+ *
+ * You can obtain optimized timing values by running Holtek IDESETUP.COM
+ * for DOS. DOS drivers get their timing values from command line, where
+ * the first value is the Recovery Time and the second value is the
+ * Active Time for each drive. Smaller value gives higher speed.
+ * In case of failures you should probably fall back to a higher value.
