<damo22>almuhs: hi

<almuhs>hi

<damo22>i have some time off work and i can work on hurd

<almuhs>I found the docs of acpica

<damo22>last night i almost got acpica compiled into gnumach, there are some errors currently

<almuhs>in the reference there are the docs of APIC functions

<almuhs>in linux, I had to install bison and flex

<almuhs>to compile acpica

<damo22>ok

<almuhs>at very first, I can test the functions in linux.

<damo22>yes

<almuhs>but I have doubts, because the docs don't explain what library I have to include

<almuhs>#include ... what?

<damo22>#include <linux/acpi.h>

<almuhs>oh, ok

<damo22>thats all i think

<almuhs>then I will try AcpiGetTable() function

<damo22>but are you using the get-repo.sh

<damo22>to filter the code to linuxized version?

<almuhs>I installed It using make

<almuhs>make && sudo make install

<damo22>dont use the upstream plain version

<damo22>its hard to read

<almuhs>then... have I to install this from repositories?

<damo22>you clone the upstream code, but you run a filter program

<damo22>it generates a new repo for you

<almuhs>oh, ok

<almuhs>I simply compiled the code

<damo22>./generate/linux/gen-repo.sh

<almuhs>ok

<damo22>just run that in the root git folder

<almuhs>done

<damo22>it will create linux-HASH/repo

<damo22>and you can use the code from in there

<damo22>there is an example tool as well

<damo22>that calls acpi functions

<damo22>i will push what ive got so far

<damo22>its still broken but the tree is there

<almuhs>I put the test file into the root acpica directory

<almuhs>?

<damo22>once it generates the code you only need what is inside linux-HASH

<damo22>the rest is useless

<almuhs>what have I to do with the contents of linux-HASH ?

<damo22>should be drivers/ include/ tools/

<almuhs>yes, It is

<damo22>try to compile the tool

<damo22>in tools/

<damo22>it will probably use your linux kernel headers

<damo22>instead of drivers/ and include/

<damo22>im not sure

<almuhs>ok

<damo22> http://git.zammit.org/gnumach-sv.git/log/?h=debian-acpica

<damo22>this almost compiles, im working on it now

<almuhs>the next step is add this inside gnumach, is not?

<damo22>it will create libacpica.a

<damo22>yes that is what i have done

<almuhs>oh, ok

<damo22>have a look at the commits

<almuhs>then, now It's necessary to create a interface between gnumach and this library

<almuhs>I'm checking the commits

<almuhs>this seems good

<damo22>there is already an interface you just #include <acpi/acpi.h> i think

<damo22>and link to libacpica.a

<damo22>but its still not compiling yet

<almuhs>then, this is the next step

<almuhs>#include <linux/acpi.h> not compiles

<almuhs>in linux

<almuhs>neither

<almuhs>Have I to add any flag to GCC for this?

<almuhs>I'm simply doing "gcc acpica_test.c -o acpica_test"

<damo22>have a look in linux-HASH/tools

<damo22>there should be a test program

<damo22>im getting multiple redefinition of symbols

<damo22>in my gnumach

<damo22>i need to add some special macros

***Server sets mode: +nt

<almuhs>but this doesn't works for me

<damo22>maybe its supposed to be built as part of a linux kernel

<damo22>have a look at the makefile

<almuhs>in linux-HASH there are not a makefile

<almuhs>maybe do I need to download the linux sources?

<damo22>AHAHA It compiled

<damo22>and linked!!

<almuhs>:D

<damo22>-rw-r--r-- 1 demo demo 7908364 Apr 24 09:40 libacpica.a

<almuhs>congrats

<damo22>and gnumach linked

<almuhs>:-)

<almuhs>now try to boot with this microkernel, to check that this doesn't crash

<damo22>theres a few warnings

<damo22>compiler

<almuhs>there are some warning during compilation

<almuhs>is not?

<damo22>yep

<damo22>theres also a couple of things i hacked to make it compile

<damo22>but only in the config

<damo22>eg spinlock_t and kmem_cache

<damo22>i dont know what they should be

<damo22>kernel boots

<almuhs>ok

<almuhs>do some tests with It and, if you want, send a patch to gnumach's upstream

<almuhs>or you prefer to test It with acpi tables before?

<damo22>i need to remove some warnings and figure out what the missing structs are for

<damo22>i should probably make it init the tables too

<damo22>and store them in a static variable

<almuhs>It's fine

<almuhs>but the current work is a good work, anyway

<damo22>:)

<almuhs>I need to go sleep, It's so late and I'm exhausted

<damo22>ok

<almuhs>write me to the maillist if you want notice me any news

<damo22>yeah

<damo22>goodnight!

<almuhs>bye, and thanks

<damo22>woot most warnings gone

<damo22>and i did it with just glue code, didnt touch the sources

<damo22>acpica is linked into gnumach and theres no missing symbols

<damo22>\o/

<damo22>how do i call a function without getting duplicate symbols?

<damo22>its failing at link time when i try to call acpi_initialize_tables()

<damo22>i can compile in the acpica but when i try to use any of the functions in a new c file, i get every symbol duplicated

<damo22>ok i figured it out i need to implement some empty stubs

***dp is now known as DP

***DP is now known as dp

<damo22>youpi: hey, ive almost added acpica to gnumach

<damo22>im missing these symbols isdigit isprint isspace isxdigit tolower toupper vsprintf

<damo22>heh it linked

<damo22>youpi: how do i get stuff to print in the kernel log?

<damo22>it boots

<damo22>but i cant read the log

<damo22>ie, i want it to appear in /var/log/dmesg

<damo22> http://git.zammit.org/gnumach-sv.git/log/?h=debian-acpica

<damo22>it boots

***rekado_ is now known as rekado

<gnu_srs1>damo22: Nice work :)
