As we talked about before; is this really correct? !is_power_of_2(0) == 
true while (0 & (0-1)) == 0.

size == 0 is also covered by the next two conditions, so the overall value
does not change.

Yes, but is it meant to state that 'size' is not a power of two? 
Otherwise, imho, it should be left as-is.

What about !one_or_less_bit()? It has not been implemented (yet?) but 
been discussed. It ended by concluding that is_power_of_2() should be 
fixed up first and then we can see about it.
And as I stated before; !is_power_of_2(size) != (size & (size-1))! It 
may be a bug but then we have to be sure it is suppose to be the power of 2.

Obviously not.

i'm not clear on what the possible problem is here:

but whether or not it's been implemented doesn't change whether or not
the code above can be simplified.  given what's being tested, and the
error message about whether a page size is valid, it seems fairly
clear that this is a power of two test.  what's the problem?

there's nothing about is_power_of_2() that needs "fixing".  it's
correct as it's currently implemented.

it may be that certain tests in the current code need to be examined
carefully to clarify what's being tested.  but the code above seems
straightforward.

Fsck, I can't see that. But if that is what's intended, well then...

(5 min later)
Ok, now I think I see it. Sorry for the noise..

Oh, I didn't mean that is_power_of_2() need to be fixed, I meant 
fixing/replacing the kernel with is_power_of_2().

i think the above change is fine.  as long as the final, overall
semantics of the condition are identical, then there's no problem.

Boot time Bluetooth BUG: warning: (value > m) at hid-core.c:793

[Fortier,Vincent [Montreal]]

[-- Attachment #1: Type: text/plain, Size: 2021 bytes --]

Hi all

I m using a Logitech MX 5000 keyboard with an included MX 1000 mouse,
both bluetooth using the same USB reciever.

When the USB reciever is already plugged-in at boot-time and the
Bluetooth service fires-up I get this message:
 =======================
BUG: warning: (value > m) at

At this point both the keyboard and mouse do not work.  I simply have to
remove/replug the reciever to make them work properly... Here is the
dmesg associated with the replug:

This means that something (I guess that it's hid2hci command?) is trying 
to pass through hiddev a value in a field that is greater than a given 
bitmask (and is not going to fit into the bitfield).

Vincent, does the problem go away when you don't use bluetooth (both 
keyboard and mouse is switched to HID mode, if they support it)?

Marcel, do you have any idea how this could happen?

Thanks,

we understand the original CSR HID proxy dongles, but for the Logitech
ones, it is wild guesses. The current support in hid2hci has been tested
on Logitech diNovo first generation and I have no other Logitech
hardware to verify it with. We might simply need the full HID report
descriptor to see who is at fault.

Marcel

Vincent,

from the stacktrace it seems that you are using pre-2.6.20 kernel. Could 
you please compile kernel with the following changes in 
drivers/usb/input/hid-core.c

- comment the #undef DEBUG and #undef DEBUG_DATA
- add #define DEBUG and #define DEBUG_DATA

and send us the output?

As far as I can see from a quick look, the device IDs are unchanged 
(0x046d/0xc70e for the keyboard), but the report descriptor seems to 
differ from the one you have at 
http://www.holtmann.org/linux/bluetooth/logitech.html - that seems pretty 
sad.

What puzzles me a bit is a fact that both the bugreporters seem to state 
pretty clearly that this started happening after some update, am I right?

Or did the hardware before work all the time in the HID mode, without even 
being attempted to switch to HCI (which seems to cause the bug)?

Actually it's the first time I'm trying this keyboard and mouse.

RE: Boot time Bluetooth BUG: warning: (value > m) at hid-core.c:793

[Fortier,Vincent [Montreal]]

Hi Jiri,

Actually I don't know... Let me test this.

Here is the scenario:
1) If I plug my USB dongle after my system has booted, everything works fine (except that the keyboard repeats a few keys somethimes..)
2) If the dongle is already plugged at boot-time, there is a BUG echo in the dmesg when the bluetooth service fires up.  This make both the mouse and keyboard unresponsive until I finally unplug / replug the dongle hence going back at state 1)

I never run the hid2hci command manually but the bluetooth init script seems to do so.

Quick test:
1- unplug/plug back the dongle to get back to state 1)
The keyboard and mouse do work has expected...
2- Now run the hid2hci command has root
[root@localhost init.d]# hid2hci
Switching device 046d:c70a to HCI mode was successful
Switching device 046d:c70e to HCI mode was successful

So yes, it looks like a hid2hci BUG or kernel BUG initiated by the hid2hci command.
