[patch] s390 kconfig cleanup, 2nd version.

[patch] s390 kconfig cleanup, 2nd version.

[Martin Schwidefsky]

Hi folks,
it has been a few weeks since the s390 kconfig discussion died down.
I have put together a new patch that includes all of the suggestions
made so far. With this patch "make allyesconfig" and "make allmodconfig"
now works on s390.

Please check that it does not break anything on your favorite 
architecture. It really shouldn't but you never know. I want to push
this patch soon.

blue skies,
  Martin.

[patch] s390: kconfig cleanup.

Use common drivers/Kconfig instead of making copies of the required
options in drivers/s390/Kconfig. Since that would add a lot of other
options that do not make sense for a s390 machine, add "depends"
statements to all options and menues that should not be there for
s390.

-	---help---
-	  A pseudo terminal (PTY) is a software device consisting of two
-	  halves: a master and a slave. The slave device behaves identical to
-	  a physical terminal; the master device is used by a process to
-	  read data from and write data to the slave, thereby emulating a
-	  terminal. Typical programs for the master side are telnet servers
-	  and xterms.
-
-	  Linux has traditionally used the BSD-like names /dev/ptyxx for
-	  masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
-	  has a number of problems. The GNU C library glibc 2.1 and later,
-	  however, supports the Unix98 naming standard: in order to acquire a
-	  pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
-	  terminal is then made available to the process and the pseudo
-	  terminal slave can be accessed as /dev/pts/<number>. What was
-	  traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
-
-	  The entries in /dev/pts/ are created on the fly by a virtual
-	  file system; therefore, if you say Y here you should say Y to
-	  "/dev/pts file system for Unix98 PTYs" as well.
-
-	  If you want to say Y here, you need to have the C library glibc 2.1
-	  or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
-	  Read the instructions in <file:Documentation/Changes> pertaining to
-	  pseudo terminals. It's safe to say N.

-	  machines which support incoming telnet/rlogin/ssh connections and/or
-	  serve several X terminals may want to increase this: every incoming
-	  connection and every xterm uses up one PTY.

Perhaps just `depends on PCI || BROKEN' (cfr. IEEE1394), so the whole menu will
be hidden for other non-PCI platforms?

I haven't implemented it yet. But it is on my list of things to do.

Ok, fine with me. One less depends on !S390.

Well, I don't like these negative !S390 depends as well. But I can't
help it, there is no other existing config symbol that can be used for a
positive dependency. Hardware that is built into the machine and is not
attached via some kind of bus does not have any dependency. The only
possible way to deal with it would be a positive list of architecture
that have that piece of hardware. But the feeling was that a negative
list is better in that case. So until you have one of your clever ideas
we are pretty much stuck, aren't we ?

But one can be invented. 

DESKTOP_HARDWARE
SMALL_IRON
END_USER_PCI
...

Chose one.

What stops users from plugging a PCI sound card into your PCI slots 
BTW?

Initially it can be set dependent on !S390 and then later migrated
into all the architectures (you can probably recruit someone on l-k
to do it if you don't want to do it yourself ...)

Since Martin added several `depends on PCI', it seems like big iron doesn't
have PCI (or perhaps PCI depends on !S390 now? :-).

None of them seems appropriate. The things the patch deactives for s390
are vastly different (ATA/IDE, Parallel port, Plug and Play, I2C, I2O
and so on). You will end up adding a lot of new config options.

Which PCI slot? s390 doesn't have PCI slots.

ATA/IDE, parallel port, PNP could be PC_STYLE_HARDWARE. 

I2O should be definitely PCI

I2C is an oddball.

Ah I thought it had. If not you can just make most of that stuff

INPUT, LEDs, GRAPHICS, SOUND could depend on USER_INTERACTION?

So basically, an s390 is a (virtual) box with only s390-specific drivers, and
the only possible generic user interaction is through the network?

Sounds like a plan. To have a clean patch from the start that new config
option PC_STYLE_HARDWARE needs to be added to almost all architectures.

> I2O should be definitely PCI

That is good to know, so I will add a "depends on PCI" for I2O.

> I2C is an oddball. 

So I leave "depends on !S390" for now.

There are still a few more config options:
  IPMI
  VT
  SERIAL_NONSTANDARD
  SCSI_SATA

and numerous menues:
  "TPM devices" - PC_STYLE_HARDWARE
  "EDAC - error detection and reporting" - PC_STYLE_HARDWARE
  "Hardware monitoring support" - PC_STYLE_HARDWARE
  "InfiniBand support" - don't think this is pc style hardware
  "Input device support" - ??
  "ISDN subsystem" - PC_STYLE_HARDWARE
  "LED devices" - PC_STYLE_HARDWARE
  "Multimedia devices" - PC_STYLE_HARDWARE
  "Misc devices" - PC_STYLE_HARDWARE
  "MMC/SD Card support" - PC_STYLE_HARDWARE
  "Memory Technology Devices (MTD)" - PC_STYLE_HARDWARE
  "PHY device support" - PC_STYLE_HARDWARE
  "Wireless LAN (non-hamradio)" - PC_STYLE_HARDWARE
  "Real Time Clock" - PC_STYLE_HARDWARE
  "Serial drivers" - PC_STYLE_HARDWARE
  "SPI support" - PC_STYLE_HARDWARE
  "Telephony Support" - PC_STYLE_HARDWARE
  "USB support" - PC_STYLE_HARDWARE
  "Graphics support" - PC_STYLE_HARDWARE
  "Dallas's 1-wire bus" - PC_STYLE_HARDWARE
  "Amateur Radio support" - PC_STYLE_HARDWARE
  "Bluetooth subsystem support" - PC_STYLE_HARDWARE
  "IrDA (infrared) subsystem support" - PC_STYLE_HARDWARE
  "Sound" - PC_STYLE_HARDWARE

Looks like PC_STYLE_HARDWARE is the clever idea I've been looking for.

It would be more general to do

	depends on !DISABLE_VT

then define DISABLE_VT over in arch/s390/Kconfig.

In fact we could adopt that as a convention and use the CONFIG_DISABLE_foo
namespace for this purpose.



Even better would be to teach the Kconfig sytem about this, so in
arch/s390/Kconfig we do

disable	VT

and the Kconfig system knows not to offer VT, so there's no need to go
adding `depends on !DISABLE_foo' all over the place.  The above DISABLE_foo
convention just simulates that missing feature.

That would be a very useful feature to have. There are some border cases
where no real positive dependency exist. For that a "disable xxx" would
be perfect. But we still should use positive dependencies where possible
to keep the disable lists short.

I was after the options that can be dealt with an existing positive
dependency, e.g. "depends on PCI", or "depends on ISA". I have a handful
of these in my patch.

I would assume that all of these depend on memory mapped I/O
access. So they might be more correctly depend on CONFIG_MMIO.

For these, it's not so clear, so maybe just let the HW drivers
depend on CONFIG_MMIO, but not the architecture in dependant
parts.

We don't (yet) have a CONFIG_MMIO.  If we were to have one, I would
expect it to be akin to SCSI_SYM53C8XX_MMIO, VIA_RHINE_MMIO,
SUNDANCE_MMIO and TULIP_MMIO.  ie indicating a preference between PIO
and MMIO rather than indicating the availability of MMIO.

Hmm, maybe my terminology wasn't so good, at least you misunderstood
what I wanted to express. PIO is more or less a 386ism, so I tend to
view that as a special case of MMIO. The point with  s390 is that there
is neither PIO nor MMIO, which really makes it impossible to use most
of the device drivers, even if you could connect the hardware ;-).

So why aren't readb() and friends in <asm/io.h> empty defines?

I understood what you wanted; I was just explaining why it's a bad name.
CONFIG_STD_IO might be a good name.  CONFIG_PCI_IO might be confusing.

I've given this a try and implemented the "disable" command. Seems to
work fine for me. The command would certainly make my life easier in
regard to the s390 Kconfig stuff.

[Kconfig] add disable command.

This patch adds the "disable <name> [if <expr>]" Kconfig command. The
purpose of the command is to allow architectures to disable specific
configuration options. For example "disable GEN_RTC" will disable
the GEN_RTC option, "disable RTC if !EXPERIMENTAL" will disable the
RTC option if the EXPERIMENTAL option is not selected.

There is one limitation of the disable command, it needs to be defined
prio to the config option it disables. The reason is that the additional
depends clause is added in menu_end_entry.

Neat.  Now we all need to cower in fear at Roman's reaction ;)

One would expect that doing "/VGA_CONSOLE" in menuconfig would answer the
question "ytf can't I enable VGA_CONSOLE".

Yes, but that's one which simply needs its conditions inverted.  eg:

Making this depend on the CPU is grosly simplifying things - and wrong.  On
MIPS the MC146818 is used in several systems but not all and chances are
the driver will crash the system if selected on some of the systems.  So
in the end I would suggeste something like in drivers/char/Kconfig:

config RTC
	tristate "Enhanced Real Time Clock Support"
	depends on SYS_HAS_MC146818

config SYS_HAS_MC146818
	bool

and somewhere from arch/*/Kconfig SYS_HAS_MC146818 will have to be selected.

The other rant of course is that the symbol CONFIG_RTC looks like it is
generic RTC support while it really only is for MC146818 and lookalikes.
So it should be renamed to something like CONFIG_MC146818.
