Docking / undocking -- /proc/acpi/ibm/dock
------------------------------------------
Docking and undocking (e.g. with the X4 UltraBase) requires some
actions to be taken by the operating system to safely make or break
the electrical connections with the dock.
The docking feature of this driver generates the following ACPI events:
ibm/dock GDCK 00000003 00000001 -- eject request
ibm/dock GDCK 00000003 00000002 -- undocked
ibm/dock GDCK 00000000 00000003 -- docked
NOTE: These events will only be generated if the laptop was docked
when originally booted. This is due to the current lack of support for
hot plugging of devices in the Linux ACPI framework. If the laptop was
booted while not in the dock, the following message is shown in the
logs:
Mar 17 01:42:34 aero kernel: thinkpad_acpi: dock device not present
In this case, no dock-related events are generated but the dock and
undock commands described below still work. They can be executed
manually or triggered by Fn key combinations (see the example acpid
configuration files included in the driver tarball package available
on the web site).
When the eject request button on the dock is pressed, the first event
above is generated. The handler for this event should issue the
following command:
echo undock > /proc/acpi/ibm/dock
After the LED on the dock goes off, it is safe to eject the laptop.
Note: if you pressed this key by mistake, go ahead and eject the
laptop, then dock it back in. Otherwise, the dock may not function as
expected.
When the laptop is docked, the third event above is generated. The
handler for this event should issue the following command to fully
enable the dock:
echo dock > /proc/acpi/ibm/dock
The contents of the /proc/acpi/ibm/dock file shows the current status
of the dock, as provided by the ACPI framework.
The docking support in this driver does not take care of enabling or
disabling any other devices you may have attached to the dock. For
example, a CD drive plugged into the UltraBase needs to be disabled or
enabled separately. See the provided example acpid configuration files
for how this can be accomplished.
There is no support yet for PCI devices that may be attached to a
docking station, e.g. in the ThinkPad Dock II. The driver currently
does not recognize, enable or disable such devices. This means that
the only docking stations currently supported are the X-series
UltraBase docks and "dumb" port replicators like the Mini Dock (the
latter don't need any ACPI support, actually).
UltraBay eject -- /proc/acpi/ibm/bay
------------------------------------
Inserting or ejecting an UltraBay device requires some actions to be
taken by the operating system to safely make or break the electrical
connections with the device.
This feature generates the following ACPI events:
ibm/bay MSTR 00000003 00000000 -- eject request
ibm/bay MSTR 00000001 00000000 -- eject lever inserted
NOTE: These events will only be generated if the UltraBay was present
when the laptop was originally booted (on the X series, the UltraBay
is in the dock, so it may not be present if the laptop was undocked).
This is due to the current lack of support for hot plugging of devices
in the Linux ACPI framework. If the laptop was booted without the
UltraBay, the following message is shown in the logs:
Mar 17 01:42:34 aero kernel: thinkpad_acpi: bay device not present
In this case, no bay-related events are generated but the eject
command described below still works. It can be executed manually or
triggered by a hot key combination.
Sliding the eject lever generates the first event shown above. The
handler for this event should take whatever actions are necessary to
shut down the device in the UltraBay (e.g. call idectl), then issue
the following command:
echo eject > /proc/acpi/ibm/bay
After the LED on the UltraBay goes off, it is safe to pull out the
device.
When the eject lever is inserted, the second event above is
generated. The handler for this event should take whatever actions are
necessary to enable the UltraBay device (e.g. call idectl).
The contents of the /proc/acpi/ibm/bay file shows the current status
of the UltraBay, as provided by the ACPI framework.
EXPERIMENTAL warm eject support on the 600e/x, A22p and A3x (To use
this feature, you need to supply the experimental=1 parameter when
loading the module):
These models do not have a button near the UltraBay device to request
a hot eject but rather require the laptop to be put to sleep
(suspend-to-ram) before the bay device is ejected or inserted).
The sequence of steps to eject the device is as follows:
echo eject > /proc/acpi/ibm/bay
put the ThinkPad to sleep
remove the drive
resume from sleep
cat /proc/acpi/ibm/bay should show that the drive was removed
On the A3x, both the UltraBay 2000 and UltraBay Plus devices are
supported. Use "eject2" instead of "eject" for the second bay.
Note: the UltraBay eject support on the 600e/x, A22p and A3x is
EXPERIMENTAL and may not work as expected. USE WITH CAUTION!

Kernel level exception handling in Linux 2.1.8
Kernel level exception handling in Linux
Commentary by Joerg Pommnitz <joerg@raleigh.ibm.com>
When a process runs in kernel mode, it often has to access user
mode memory whose address has been passed by an untrusted program.
When a process runs in kernel mode, it often has to access user
mode memory whose address has been passed by an untrusted program.
To protect itself the kernel has to verify this address.
In older versions of Linux this was done with the
int verify_area(int type, const void * addr, unsigned long size)
In older versions of Linux this was done with the
int verify_area(int type, const void * addr, unsigned long size)
function (which has since been replaced by access_ok()).
This function verified that the memory area starting at address
This function verified that the memory area starting at address
'addr' and of size 'size' was accessible for the operation specified
in type (read or write). To do this, verify_read had to look up the
virtual memory area (vma) that contained the address addr. In the
normal case (correctly working program), this test was successful.
in type (read or write). To do this, verify_read had to look up the
virtual memory area (vma) that contained the address addr. In the
normal case (correctly working program), this test was successful.
It only failed for a few buggy programs. In some kernel profiling
tests, this normally unneeded verification used up a considerable
amount of time.
To overcome this situation, Linus decided to let the virtual memory
To overcome this situation, Linus decided to let the virtual memory
hardware present in every Linux-capable CPU handle this test.
How does this work?
Whenever the kernel tries to access an address that is currently not
accessible, the CPU generates a page fault exception and calls the
page fault handler
Whenever the kernel tries to access an address that is currently not
accessible, the CPU generates a page fault exception and calls the
page fault handler
void do_page_fault(struct pt_regs *regs, unsigned long error_code)
in arch/i386/mm/fault.c. The parameters on the stack are set up by
the low level assembly glue in arch/i386/kernel/entry.S. The parameter
regs is a pointer to the saved registers on the stack, error_code
in arch/x86/mm/fault.c. The parameters on the stack are set up by
the low level assembly glue in arch/x86/kernel/entry_32.S. The parameter
regs is a pointer to the saved registers on the stack, error_code
contains a reason code for the exception.
do_page_fault first obtains the unaccessible address from the CPU
control register CR2. If the address is within the virtual address
space of the process, the fault probably occurred, because the page
was not swapped in, write protected or something similar. However,
we are interested in the other case: the address is not valid, there
is no vma that contains this address. In this case, the kernel jumps
to the bad_area label.

Where does fixup point to?
Since we jump to the contents of fixup, fixup obviously points
to executable code. This code is hidden inside the user access macros.
