Not having seen much of all the work, this sounds like it is a sad day,
for Martin who contributed a lot of his time to work on the issues,
while people seemed not to be too grateful, screaming from either end of
the road, this must wear people out.

Is there a way how the improvements that parts of the stuff have
received can be rescued somehow? Or at least the knowledge of which can
be used somewhat directly for a IDE-TNG driver? I'd find it really sad
to just let go of so much time that had been invested into the project

I will hand it to you guys on a silver platter IDE-TNG.

Below yields modular chipsets and channel index registration.
Selectable IOPS for arch independent Taskfile Transport layers.
Now to finish the job with device class link lists to address fully
modular subdrivers.  It also includes 1st generation of device open and
select calls of subdrivers.

You have ide-cd registered on a cdrw and you want to burn a cd?
open(/dev/hdX) transform_subdriver_scsi close(/dev/hdX)
open(/dev/sg) and burn baby burn.
close(/dev/sg) releases transform_subdriver_scsi
open(/dev/hdX) load native atapi transport.

Will do it for TAPE-FLOPPY-DVDCD/RW ...

Re: IDE? IDE-TNG driver

You can do the switch (one way only right now) in 2.4.20-pre2-ac3.
Ultimately for 2.4 I want to get to the point where open() tries to
switch between srfoo and hdfoo and locks out the other user. For 2.5 we
can get more esoteric. 2.4 has to continue to just work

Andre, I see the thought, but surely this is prine to races and other 
difficulties.

Wouldn't it be better to provide an IDE ioctl() that enables the caller to use 
set the SCSI transport on an open FD, so your sequence becomes:

 open(/dev/hdX)
 ioctl(transform_subdriver_scsi)
 ioctl(scsi_ops)
 write(data)
 close(/dev/hdX)

Re: IDE? IDE-TNG driver

[Andre Hedrick]

ide_ioctl(fd, HDIO_SET_IDE_SCSI, bool)

Where bool does the subdriver switch.
Just that ioctl's are being blasted and people using are frowned upon.

This was a feature Alan Cox poked me for to try and move away from how
modules are basically an all or nothing grab-all.

? so how is cdrecord (or whatever) supposed to do its stuff -- is it ioctl()  
-> fcntl()? If so, I suppose that's ok, but the basic premise still exists,
surely?

I don't think modules are the answer to any of this:
 a) some people want basically module-less kernels
 b) in some environments, you need to be able to select the IO mechanism 
    without the ability to select the module to load.

anyway...

This is designed to work regardless.

/dev/hdc == ide-cd builtin
insmod ide-scsi

ide_ioctl(fd, HDIO_SET_IDE_SCSI, bool)

converts /dev/hdc == ide-cd builtin to ide-scsi(add-in-module).

See above, I think it solves the problem.
Once ide-scsi is added to the ide_module link list it is as good as
built-in.

Me too, because I do not know the direction goal so I am doing the very
best I can.  What I really need is an active development team.

Before me:

Mark Lord, Gadi Oxman, Eric Anderson worked well.

ML ide-disk and ide.c global.
GO ide-floppy, ide-tape, ide-scsi
EA ide-cd

Anyways that was long before transport layer w/ all the hardware issues
began to dominate things.

If that's the case, won't a kernel parameter suffice?  Can you

Wouldn't the logic be a lot simpler if kernel developers didn't have to 
worry about whether their module was built in or inserted at some point in 
the future?  All the bits could be assembled and symbols would be resolved 
at compile time.

ICBW but it appears the largest percentage of users have modules inserted 
at boot time, never to be ejected or disturbed.  The modules might as well 
be built in.

I've never really grokked the whole initrd anyway.  What is the point of 
building a kernel minus the bits it needs to actually boot the system?  
That just forces this ludicrous jerry-rigged mess to provide the 
capabilities that should have been built in at compile time.

Of course, we're never going to get away from modules now anyway, so the 
argument is probably moot.  With PCCARD, USB, Firewire, and Hotplug PCI 
there are too many ways to add components not present when the system is 
built on an adhoc basis.  The alternative would be a bloated monstrosity 
with dead code not needed by most people.  I remember my early days of 
Linux and seeing literally dozens of kernels compiled with different 
options, with no clue how to choose the right one for my system.

Because I shouldn't have to use a feature if I don't need to use a
feature?

I dunno... I've not once heard a decent argument as to why I should
modulerise the ide subsystem, or ext3 or the video drivers and so on.

Where I -do- need to use it though, I do happily use it. One case is to
reset the eepro100 driver so that it works after my computer is brought
out of suspend mode (either RAM or disk).

But why should I -not- make a monolithic kernel when I don't have any
reason to do so? If you can provide me with some decent ones, I'll
happily start...

Re: IDE? IDE-TNG driver

[David Lang]

A couple things in favor of a monlithic kernel.

there is a slight performance advantage becouse the calls don't
have to be far calls

there is a slight memory advantage becouse you don't have the fraction of
a page of ram lost per module

with a monolithic kernel there's no chance of making a mistake and trying
to use incompatable modules with your kernel (and before you say that this
can be fixed with the kernel build remember that for many people the build
machine is not where the kernel will be run)

1. "No need".  Doesn't apply to everybody of course, but
   many have enough memory and don't plug in much new stuff.
   Recompiling & booting for the rare occation where you
   bought a new usb device is ok.  

2. A simpler setup.  No /etc/modules.conf to worry about.
   Compiling ALSA into the kernel surely made life easier.
   even more so when also using devfs...

3. Performance.  Compiled-in stuff is always there, and
   on x86 it exists in the kernel's 4M page so no
   TLB loading overhead either.

> Someone replied off-list saying that initrds are too hard to create.
Actually, that isn't an argument for linking everything in.
All you need is the drivers for your root fs and root device.
The rest may still be modular, loaded from /lib/modules on
that root fs.

Will it support DISCONNECT/RECONNECT ( of course named differently
in ATA, "overlapped command feature" if I'm not mistaken ) ?

If not, consider this as a request for implementation :-)
I can offer (beta)testing ( I have two ATAPI CD-ROMs ( one is a
rewriter ) and a HD , that all claim ( according to hdparm -I output )
to support overlapped commands ) and maybe money, if everything else
fails :-)

I expect this to improve performance ( latency actually ) on the ATA
channel when slow devices are involved ( and even fast devices can have
slow moments, like a read of a slightly broken sector ).
