region size computed incorrectly

region size computed incorrectly

[Albert Cahalan]

Consider the following chunk of code, produced by
the Intel disassembler:

                Device (HPET)
                {
                    Name (_HID, EisaId ("PNP0103"))
                    Name (_CRS, ResourceTemplate ()
                    {
                        IRQNoFlags () {0}
                        IRQNoFlags () {8}
                        Memory32Fixed (ReadOnly, 0xFEC01000, 0x00000400)
                    })
                    OperationRegion (^LPCR, PCI_Config, 0xA0, 0x04)
                    Field (^LPCR, AnyAcc, NoLock, Preserve)
                    {
                        HPTE,   32
                    }

                    Method (_STA, 0, NotSerialized)
                    {
                        And (HPTE, 0x01, Local0)
                        If (Local0)
                        {
                            Return (0x0F)
                        }

                        Return (0x00)
                    }
                }


There we have a 4-byte OperationRegion with a 32-bit
field called HPTE. That fits. Then, in _STA, HPTE is
read, and linux-2.6.0-test3 spits out errors:

Somehow, the LPCR region is being seen as length 0.
This is not correct; it is 4 bytes wide. Until the
boundry checking is fixed, it should be disabled.
Even then, a minor overflow should just printk() a
warning and keep on going.

BTW, what is a PNP0103 device?

RE: region size computed incorrectly

[Grover, Andrew]

I was able to reproduce this. Putting LPCR in the HPET scope instead of
the parent scope (by removing the ^s) seems to be a temporary
workaround. We appear to be creating 2 LPCR objects, 1 of which is
initialized correctly and 1 which is zeroed out. We look at the
not-initialized one, and throw errors.

BTW PNP0103 is the HPET, High Precision Event Timer. I don't know how
people are supposed to request PNP IDs these days, but the HPET spec
says 0103, so I guess they got it. :)

I was patiently waiting for sourceforge ACPI page to be updated but as 
it does not happen (Andrew?) I tried your patch and found one problem 
with it and one with the patch itself :

1) The patch does not apply correctly for driver/acpi/Config.in. As It 
is a single block to replace, I copied the new block by hand but then 
xconfig started to fail. I just reverted to original version.

2) I own a A7V that has been blacklisted by last patch while I have been 
using ACPI (mainly for software power off via power button on this 
machine :-)). Using ht only, I lost silently this feature and halted my 
machine without any form of sync which is rather bad... Seeing the 
message concerning blacklisted machine, I tried with acpi=force at boot 
time and of course booted sucessfully. Here is the dmesg attached. May I 
have a few words about the reason why this machine has been blacklisted?

It definitely applies to 2.4.22-rc2 here...  weird.

I'll let the ACPI guys take this one...

Sure. Thanks for providing the patch... I hope sourceforge will be 
updated : I do not want to use BK juste for testing ACPI on my two 
personnal machines...

Does not work for me but this is not important : I just wanted to let 
you know. Note that as I have reached this state by applying all 
incremental patches and not directly 2.4.22-rc2 on top of a 2.4.21.

  I own a A7V that has been blacklisted by last patch while I have been
using ACPI (mainly for software power off via power button on this
machine :-)). Using ht only, I lost silently this feature and halted my
machine without any form of sync which is rather bad... Seeing the
message concerning blacklisted machine, I tried with acpi=force at boot
time and of course booted sucessfully. Here is the dmesg attached. May I
have a few words about the reason why this machine has been blacklisted?

NB : when you have young childs or a wife that does not want to hear 
about linux, power off button software controlled is indeed a great 
faeture :-)
