Git changeset 6bdcc6e6db dropped the
stand-alone lgh06xf module, whose functionality was absorbed into the
dvb-pll module. However, there was a minor difference between the code
in lgh06xf and dvb-pll, which caused a regression in b2c2-flexcop
devices using the LG-H06xF NIM.
dvb-pll will probe for the presence of an i2c pll chip by performing a
single byte read, the lgh06xf driver did not do this. Unfortunately, the
code in flexcop-i2c.c does not currently support 1 byte or 0 byte reads
as a probe. Such probes with the current code will always fail.
In order to work around this problem, and restore proper functionality
of the Airstar HD5000 device, this hack was created to make the probe
appear to succeed. The single byte read in dvb_pll_attach is the only
place where such a probe would ever occur, so this change is safe, and
will not affect any other devices.
Of course, if one knew how to actually perform the read operation, it
would be better to go that route. In the meantime, however, we must
apply this workaround, in order to prevent the regression that causes
tuning to fail on the Airstar HD5000 ATSC device.
Thanks to Jarod Wilson, who had originally reported this regression, and
to Geoffrey Hausheer, whose original workaround patch led us to find the
actual cause of the problem.

Furthermore, the precise before-C2/C3-sleep and after-C2/C3-wakeup

Also, clear the stored bits and clear the interrupt registers before

The uart_set_termios() function will bail out early without bothering to
touch the hardware, if it decides that nothing "relevant" has changed.
Unfortunately, its idea of "relevant" doesn't include c_[io]speed. So if
the baud rate bits are BOTHER and you just change the speed, the change
gets optimised away.
This patch makes it ignore the old Bfoo bits in c_cflag and just check
whether c_ispeed and c_ospeed have changed. Those integers are always set
appropriately for us by set_termios().

The k8t_sound_hostbridge PCI quick fires on my motherboard (Jetway
K8M8MS) while it shouldn't: the on-board sound chip is not disabled
and is working just fine. Looking at the code, I see that we are
running the quirk for two distinct register values (0x88 and 0xc8)
and then clear bit 6 (0x40). However value 0x88 already has bit 6
cleared so this is a no-op. This is what happens on my board. Thus I
believe that the quirk should only be run for register value 0xc8.

Ok, lets kill the message. As Alois Nešpor also saw, that's fixed up by Yenta,
so PCI does not have to warn about it. PCI could still warn about it if
is_cardbus is 0 in that instance of pci_scan_bridge(), but so far I have
not seen a report where this would have been the case so I think we can
spare the kernel of that check (removes ~300 lines of asm) unless debugging
is done.
History: The whole check was added in the days before we had the fixup
for this in Yenta and pci=assign-busses was the only way to get CardBus
cards detected on many (not all) of the machines which give this warning.
In theory, there could be cases when this warning would be triggered and
it's not cardbus, then the warning should still apply, but I think this
should only be the case when working on a completely broken PCI setup,
but one may have already enabled the debug code in drivers/pci and the
patched check would then trigger.
I do not sign this off yet because it's completely untested so far, but
everyone is free to test it (with the #ifdef DEBUG replaced by #if 1 and
pr_debug( changed to printk(.
We may also dump the whole check (remove everything within the #ifdef from
the source) if that's perferred.
On Alois Nešpor's machine this would then (only when debugging) this message:
"PCI: Bus #0b (-#0e) is partially hidden behind transparent bridge #0a (-#0b)"
"partially" should be in the message on his machine because #0b of #0b-#0e
is reachable behind #0a-#0b, but not #0c-#0e.
But that differentiation is now moot anyway because the fixup in Yenta takes
care of it as far as I could see so far, which means that unless somebody
is debugging a totally broken PCI setup, this message is not needed anymore,
not even for debugging PCI.
Ok, here the patch with the following changes:
* Refined to say that the bus is only partially hidden when the parent
bus numbers are not totally way off (outside of) the child bus range
* remove the reference to pci=assign-busses and the plea to report it
We could add a pure source code-only comment to keep a reference to
pci=assign-busses the in case when this is triggered by someone who
is debugging the cause of this message and looking the way to solve it.
