Kernel Compilation Project – Status update
——————————————-
This document tries to give a brief update about the Kernel
Compilation Project.

In the last weeks, a lot of small but anoying bugs are fixed
(bug thanks to Alan Cox for pointing me in the right direction) and
a most fixes are in the AC-series. For some problems I have a
solution but it is not “nice enough” to be in mainstream
kernel.

Results
——-
Yesterday, I ran a series of compiles on 2.1.131ac7 + my fixes, and
about 75% of the compiles was succesfull (BIG improvement, for
example 2.1.125 compiled in about 3%). For the Kernel Compilation
Project to work, this has to go up to (at least) 95%. Until that
time, no distributed system is workable since a _LOT_ of the same
bugs will be reported.

Remaining bugs
————–

• ISDN subsystem
  • The ISDN-subsystem calls icmp_send for a broken link; it
    shouldn’t since TCP/IP is not always available (violation of
    OSI-layers)
  • Several HiSax-drivers depend on PPP for a CRC-table. This table
    is used very often, I think it should get it’s own file
  • There is a nameclash between the act2000-isdn card and the
    hisax-drivers about a “cards” structure
  • ISDN_PPP depends on TCP/IP for VJ-header compression. Shouldn’t
    since TCP/IP isn’t always available (for example, for
    security-reasons)
  • The ISDN-subsytem doesn’t compile if CONFIG_NET isn’t set
    (Would be great for an old 386 to serve as answering machine)
• PPP
  • PPP depends on TCP/IP for header-compression; same reasons as
    for ISDN
• HFMODEM
  • several drivers depend on the CRC-table of PPP; needs it’s own
    file
  • “hfmodem_refclock_setscale” is called but neither I nor my
    compiler can find it
• IrDA
  • Has several strange things (ac8 should fix; my machine is busy
    🙂
• HDLCdrv
  • Fails if AX25 is compiled as a module but hdlcdrv isn’t
• linking-order
  • Several drivers depend on a linking order in the toplevel
    Makefile. Strange things going on here… Can give examples if
    someone feels like fixing these.
• Radio-MIROPCM20
  • depends on the lowlevel-sound ACI-driver, but this one is asked
    later in the ‘make config’ process (yuck!)
• Misc config
  • CONFIG_SDLA must be compiled as a Module
  • Promise DC4030 depends on CONFIG_BLK_DEV_IDEDISK
  • HIPPI depends on TCP/IP

Time to go fix 🙂
Help appriciated! (.config-files available on request)
