acpi_thread_id = acpi_os_get_thread_id()

Bob,
with the new type acpi_thread_id, it seems that the thread_id grows from
32-bits
to 64-bits on a 64-bit mahcine.

acpi_os_get_thread_id() currently returns task.pid on Linux,
a 32-bit integer on both 32 and 64-bit machines.

So if acpi_os_get_thread_id() is called at interrupt level,
its return value is meaningless.

Linux doesn't define ACPI_MUTEX_DEBUG, and looks like it never will.

Is it possible to delete the concept of acpi_os_get_thread_id()?
I'm wondering at the moment if the right thing isn't to do this:

#define acpi_os_get_thread_id() (0)

thanks,
-Len

Currently I cannot reproduce this, this may have to do with:

 - moved pl2303 adapter from one usb2 hub to another because kernel
barfed about it and that solved the barfing
 - compiled various versions of the kernel so many times, I lost track
of the exact config
 - different usb hub and perifs at home and at work.

As soon as I can reproduce the issue, I'll file a proper bug report

Compilation warnings in the current git tree.

Hi all.

Previous comment not-withstanding, there are some issues I found with current git. Apologies to anyone
wrongly cc'd :)

Hope this helps.

Regards,

Nigel

ACPI for Kernel 2.6.16

Hello, 

Hello, I would like to know when would be available the patch ACPI for the 
version 2.6.16.1 of kernel GNU / LINUX?
Can the patch for the version 2.6.16 RC1 work on my version?
I thank you beforehand.

Bye

Help with Averatec C3500

Hello all,
 I have an Averatec C3500 Convertible Tablet PC.  With the initial bios 
version that ships with the unit, USB and PCMCIA both work fine in 
linux.  However, there is a terrible keyboard lag and dropped keys.  The 
follow-on bios revisions fixed the keyboard issues, but caused USB and 
PCMCIA to both stop working.  Note: All devices continue to operate fine 
in Windows.  I'm posting this here in hopes that someone will take 
interest in this issue ( there are several others trying to use linux on 
these laptops. )  I've captured dmesg output after enabling 
CONFIG_USB_DEBUG and CONFIG_PCMCIA_DEBUG in the kernel config, and the 
output from lspci -vvxxx, as well as the DSDT output from both the 
original BIOS ( USB working / Keyboard not ) and the latest BIOS 
revision ( USB Not working / Keyboard works great ).

The link for all this captured data is: http://www.linuxkidd.com/c3500   
I've detailed the machine hardware, running kernel, etc.. as well as 
linked to all the above described captures.

After posting the above request to the linux-usb list, Alan Stern 
responded with:
----------------------------------------------------------------------
According to the log, the I/O memory mappings for the USB and PCMCIA
controllers aren't getting set up. It's not a USB or PCMCIA issue at all;
you should ask for help on the PCI and ACPI mailing lists.
----------------------------------------------------------------------

So, here I am...

If there's anything else I can provide to assist in troubleshooting,
Please ask!  I'd really like to get this working.

What about simply offering the prototypes unconditionally?

acpi test branch -- history rebase

Folks,
Please nuke your local copy of my acpi test branch before you pull it again.
I needed to check in modified versions of some of the patches and the will
conflict with the original versions.

thanks,

duh, yes, that should be OK AFAIK.  Could you do that?
