[parisc-linux] ? New status of MUX or SCSI driver on E-series (and other...)

[parisc-linux] ? New status of MUX or SCSI driver on E-series (and other...)

[Christoph Plattner]

After such long time, I want to ask, if there any news?

Where there experiences (with logic analysator, etc...), if the
SCSI chip is accessed ?

Are there any news in accessing another port then port "0" on the
MUX. My experiments using "only" port "1" was also not successful,
the machine blocks !

Perhaps the PDC ROM setup influences the MUX device.

Answer is welcome.
Christoph

Hello Christoph,

On the todo list ... still no forward progress yet :(

The mux has been ported to linux-2.5, the major number 11 was assigned,
and linus accepted it into his tree.  Last night I found the problem
that caused the init failure with the mux so the mux boots again
on 2.5.47.  The forward port is more flexible and is better designed 
to handle handle multiple muxes and the access to the ports.  I am
working with robbie to test the multiple mux cards now, and plan to
test the multiple ports here shortly (need to find my cables first.)


On a side note, I have also port-forwarded the pdc_console to the 
linux-2.5 tree and will finish testing it here shortly.  I will send 
you the updated pdc_console to review before I commit it.

Not sure ... planning on testing shortly  (this weekend possibly)

Thanks,

[parisc-linux] .PARISC.unwind where is it for pa2.0w?

[phi]

Hi All,

Where is the "Section: .PARISC.unwind" for palinux2.0w doing an elfdump on the
kernel I don't see it?

Is it implemented differently

Thanx in advance
Phi

looks like we link it into the .text section:

  .text BLOCK(16) : {
        *(.text*)
        *(.PARISC.unwind)
        *(.fixup)
        *(.lock.text)           /* out-of-line lock text */
        *(.gnu.warning)
        } = 0

(arch/parisc/vmlinux64.lds for linux-2.4; arch/parisc/vmlinux.lds.S
for linux-2.5).  why we do this, i don't know; i'm not a toolchain kind
of guy ;-)

in the kdb branch this was moved (perhaps more appropriately) to the
data section, and surrounded by markers so that you can find the
begin/end. i will add this change to the 2.5 branch. In fact, it
probably should be in the rodata section....
