-T
Perform timings of cache reads for benchmark and comparison
purposes. For meaningful results, this operation should be repeated
2-3 times on an otherwise inactive system (no other active processes)
with at least a couple of megabytes of free memory. This displays the
speed of reading directly from the Linux buffer cache without disk
access. This measurement is essentially an indication of the
throughput of the processor, cache, and memory of the system under
test. If the -t flag is also specified, then a correction factor based
on the outcome of -T will be incorporated into the result reported for
the -t operation.

-t
Perform timings of device reads for benchmark and comparison purposes.
For meaningful results, this operation should be repeated 2-3 times on
an otherwise inactive system (no other active processes) with at least
a couple of megabytes of free memory. This displays the speed of
reading through the buffer cache to the disk without any prior caching
of data. This measurement is an indication of how fast the drive can
sustain sequential data reads under Linux, without any filesystem
overhead. To ensure accurate measurments, the buffer cache is flushed
during the processing of -t using the BLKFLSBUF ioctl. If the -T flag
is also specified, then a correction factor based on the outcome of -T
will be incorporated into the result reported for the -t operation.

from improved performance using a command sequence similar to this:

ASC39160/64bitPCI + Atlas10KIII/18GBです。
10000rpmsだけど今まで使ってたIBM DNES309170より
遥かに静か、かつ無茶苦茶速いです。(シーク音は箱に入った
砂をざーっと何かに出すような音ですが、慣れればIBMより
静かです)

なるる。 10000rpm/64bit PCI クラスですか。
うぅ、あちきのような素人には高価で手が出せませぬ。。。

やっと、udma5が使えるようになりました。

気づかなかったけど、VIA VT82* South Bridge 使ってる場合、
RedHat7.2、付属のドライバ(via82cxxx.o)ではudma3/4/5が使えないみたい。
より新しいカーネルのドライバを使うと良いと思います。

(RedHat7.2のカーネルソース持ってる人は、
linux/drivers/ide/via82cxxx.c の436行目、
via_80w = 0;
っていうのをコメントアウトするとうまくいくかもしれません。
見たかんじ、これがケーブルの検出を無効にしてるみたいなので…
責任は持てませんが、私の場合はうまく動いるみたいです)

やっぱりサウスの責任かなぁ。
CPU は k6-III と Pen3-700 で hdparm -t の数値ぜんぜん

hdparm -I で見ると /dev/hdc は udma4 に * が付くので ATA66

udma2 のままでいい。
実は ATA100 用ケーブル繋いだ /dev/hdc を udma4 で使ってみて
ぜんぜん改善しなかったので /dev/hda のほうを udma4 化する気力を
なくしてる ...

指摘どうもありがとうございました。たしかにDMA off でした。しかし、

ははは。そりゃ、いくら俺でも root でやっとるよ。ついでに umount してやって
みたがそれでもダメ。root じゃなければ Permission denied ってでるわな。

おれも Intel 845GE, Intel ICH4 なマザボで DMA on に出来なかった。
kernel に -ac patch あてたら DMA on になったよ。

>>114
サンクス。言われて思いついて調べてみた。俺の場合 KT333
なんだけど 2.4.19-pre5 以上でないと dma つかえないらしい。
原因わかったんでそのうち kernel を新しくするわ。

>>107
それは、-Tの数値を理解していないと思われ。
manにもわりと詳しくかいてある。読め。

ヲレも2.4.19のときDMA onに出来なかったのでパッチあてたよ
2.4.20でカーネル作り直したら，そのままでDMA使用できた．

ケーブルがふるいタイプのものだと、実力が出せなかったりするし、
なぜかしらないがVine2.5だと、/etc のしたにあるコンフィグレーション
ファイルでDMAをオンにしないと、デフォルトではPIOでHDDがつながっている。

>>118
どのファイルですか? fstab? 俺もしかしたらそれに当っているかも知れない。

>>119
/etc/sysconfig/harddisks

>>120 サンクス。たしかに comment out されてるね。しらんかった。安全の為らしいが。

ここはpureIDE限定デスカー？

>>105
pupu.
strerror()がSUCCESS（藁

>>114-117
そういうのは大概，パッチ無くともDeviceID書き加えるだけでOKと成り候。

>>122
チップセットが新しい場合でも？
ちなみに自分の場合は845Gだったんだけど
パッチ当てる，もしくは2.4.20でカーネルをつくり直さないと
DMAをONに出来なかった．
時間があればDeviceIDをどのように書き加えればいいのか
ポインタだけでもいいから教えて.

VIA の VT82* チップの載ったマザーを使っているんだけど、
どうしても udma3/4/5 が有効にならないんです。

2.4.20 に ac パッチ当てて使ってみてるんですが。
それとも何かカーネルの設定で必要な項目とかあるのですかね。

DupliDisk IDE RAID-1 Adapter の先にATA100対応のディスクが付いてます。
DupliDisk って製品は ATA66 対応を謳ってるRAIDコントローラです。

今気づいたんですが、Cable Type が 40w として認識されて
しまってるのが原因っぽいですね。Dupli Diskに付属のケーブル
を使っているのですが、マニュアルに通常のATAケーブルじゃ駄目だ
と書いていたので素直に従ってるんですけどね。

一応、製品仕様には 80wire - 40pin Connector とあります。

もしかすると、カーネルの問題かもしれず。

/usr/src/linux/drivers/ide/via82cxxx.c

の中で、無条件に via_80w に 0 を入れている場面があれば、犯人はカーネルです。
変なパッチが当てられてると思うので、そのパッチを抜いて再構築ですな。

# ちなみに、Vine-2.5 の　kernel-2.4.18-0vl3 はその問題を抱えてました。

>>123
最高に手抜きな方法。
まったくの新設計チップだとちと困るが，同系統のチップが以前にある場合…
2.4系カーネルなら
linux/include/pci_ids.h
にある同系統チップのDeviceIDを自前のものに書き換える。

845GのICH4ならICH3のDeviceIDを置き換えてしまうといいだろう。

>>130
どうも
でも、厨なんでいまいちよく分からない、もうちょっと教えとくれ
dmesg見たら
---------------------------
Transparent bridge - Intel Corp. 82801BA/CA/DB PCI Bridge
.......
i810: Intel ICH4 found at IO 0xe400 and 0xe000, IRQ 11
.......

のように書かれていたので
pci_ids.hの
#define ....INTEL_82801BA_[0-9] hoge
のところの hogeの値を 0xe400 0xe000とかに替えて
カーネル作りなおしたらいいの?

のぉ、厨にわかるよう説明するの下調べが面倒臭い。。。

自分のIDEコントローラの調べ方：
* PCI_IDE: unknown IDE controller on PCI bus xx device xx, VID=xxxx, DID=xxxx

対応してない(unknown)なコントローラなら、VID=xxxx DID=xxxx として
Vendor、Deviceの各IDが表示される。

置換元のDeviceの調べ方:
linux/drivers/pci/pci.ids
や
http://pciids.sf.net/
を見て、旧世代のIDEコントローラのIDを探す。

* (VID)8086 (DIV)244b (Desc.)82801BA IDE U100

今回はこのICH2 UDMA100コントローラを生贄にしてみようか。

実際に置換する：
linux/include/linux/pci_ids.h内で、先の置換元を探すと

#define PCI_DEVICE_ID_INTEL_82801BA_9 0x244b

とある。これを書き換え。
#define PCI_DEVICE_ID_INTEL_82801BA_9 0xXXXX
(DID:244b->XXXX)
とすれば良い。

わが国のＩＴはユーザに使用法を十分説明する時間がありません。
このため、初心者がベテランに疑問についてたずねる光景を目にすることがあります。
しかし本来は事故（情報漏えいなど）が発生した場合の責任は、
接続業者、サーバ運営者、システムを開発したエンジニアにあります。
メーカあるいは購入店にたずねるべきです。
利用者の仕事は自治（掲示板の秩序を守ること）です。助言を行ってはなりません。
素人が専門技術に言及するのは「親切」ではありません。「無責任」です。
海外のプロフェッショナルは、「私の仕事ではない」と答えるはずです。

Intel の SSD 80G だよん。
思えば遠くへ来たもんだ。

>>389
おおー速い
よさそうだね
起動速度も凄い？

起動はメチャ速くなりました。
要らんモジュールは削ってるけど、それでも速いです。
躊躇せず再起動できます。

まだあまり使い込んでるわけではないので、アレですけど
read は速くて write は期待したほどじゃない感じでしょうか。
tar の展開とか遅いなあって感じが、なんとなく。
ただ、これは気のせいかもしれません。
