hwmon: (k8temp) Bypass core swapping on single-core processors

Commit a2e066bba2aad6583e3ff648bf28339d6c9f0898 introduced core
swapping for CPU models 64 and later. I recently had a report about
a Sempron 3200+, model 95, for which this patch broke temperature
reading. It happens that this is a single-core processor, so the
effect of the swapping was to read a temperature value for a core
that didn't exist, leading to an incorrect value (-49 degrees C.)

Disabling core swapping on singe-core processors should fix this.

Additional comment from Andreas:

The BKDG says

  Thermal Sensor Core Select (ThermSenseCoreSel)-Bit 2. This bit
  selects the CPU whose temperature is reported in the CurTemp
  field. This bit only applies to dual core processors. For
  single core processors CPU0 Thermal Sensor is always selected.

k8temp_probe() correctly detected that SEL_CORE can't be used on single
core CPU. Thus k8temp did never update the temperature values stored
in temp[1][x] and -49 degrees was reported. For single core CPUs we
must use the values read into temp[0][x].

PCI/PM: Do not use native PCIe PME by default

Commit c7f486567c1d0acd2e4166c47069835b9f75e77b
(PCI PM: PCIe PME root port service driver) causes the native PCIe
PME signaling to be used by default, if the BIOS allows the kernel to
control the standard configuration registers of PCIe root ports.
However, the native PCIe PME is coupled to the native PCIe hotplug
and calling pcie_pme_acpi_setup() makes some BIOSes expect that
the native PCIe hotplug will be used as well.  That, in turn, causes
problems to appear on systems where the PCIe hotplug driver is not
loaded.  The usual symptom, as reported by Jaroslav Kameník and
others, is that the ACPI GPE associated with PCIe hotplug keeps
firing continuously causing kacpid to take substantial percentage
of CPU time.

To work around this issue, change the default so that the native
PCIe PME signaling is only used if directly requested with the help
of the pcie_pme= command line switch.

Fixes https://bugzilla.kernel.org/show_bug.cgi?id=15924 , which is

ACPI / PM: Do not enable GPEs for system wakeup in advance

After commit 9630bdd9b15d2f489c646d8bc04b60e53eb5ec78
(ACPI: Use GPE reference counting to support shared GPEs) the wakeup
enable mask bits of GPEs are set as soon as the GPEs are enabled to
wake up the system.  Unfortunately, this leads to a regression
reported by Michal Hocko, where a system is woken up from ACPI S5 by
a device that is not supposed to do that, because the wakeup enable
mask bit of this device's GPE is always set when
acpi_enter_sleep_state() calls acpi_hw_enable_all_wakeup_gpes(),
although it should only be set if the device is supposed to wake up
the system from the target state.

To work around this issue, rework the ACPI power management code so
that GPEs are not enabled to wake up the system upfront, but only
during a system state transition when the target state of the system
is known.  [Of course, this means that the reference counting of
"wakeup" GPEs doesn't really make sense and it is sufficient to
set/unset the wakeup mask bits for them during system sleep
transitions.  This will allow us to simplify the GPE handling code
quite a bit, but that change is too intrusive for 2.6.35.]

has FIFO support. This FIFO provides additional data buffering. It

times. More details of the FIFO operation can be found at

http://focus.ti.com/general/docs/lit/getliterature.tsp?literatureNumber=sprufm1&fileType=pdf

Existing sequence of steps for audio playback/capture are:
a. DMA configuration
b. McASP configuration (configures and enables FIFO)
c. Start DMA
d. Start McASP (enables FIFO)

was being enabled in davinci_hw_common_param() function of
sound/soc/davinci/davinci-mcasp.c file. This generated a transmit
DMA event, which gets serviced when DMA is started.

https://patchwork.kernel.org/patch/84611/ patch clears the DMA
events before starting DMA, which is the right thing to do. But
this resulted in a state where DMA was waiting for an event from
McASP (after step c above), but the event which was already there,
has got cleared (because of step b above).

OMAPFB: LCDC: change update_mode to DISABLED when going suspend

I was observing the following error messages on my OMAP1 based Amstrad Delta
board when first changing from text to graphics mode or vice versa after the
LCD display had been blanked:
omapfb omapfb: timeout waiting for FRAME DONE
with a followup error message while unblanking it back:
omapfb omapfb: resetting (status 0xffffffb2,reset count 1)
As a visible result, image pixels happened to be shifted by a few bits,
giving wrong colors.

Examining the code, I found that this problem occures when an OMAP1 internal
LCD controller is disabled from omap_lcdc_suspend() and then a subsequent
omap_lcdc_setup_plane() calls disable_controller() again. This potentially
error provoking behaviour is triggered by the lcdc.update_mode flag being kept
at OMAP_AUTO_UPDATE, regardless of the controller and panel being suspended.

This patch tries to correct the problem by replacing both omap_lcdc_suspend()
and omap_lcdc_resume() function bodies with single calls to
omap_lcdc_set_update_mode() with a respective OMAP_UPDATE_DISABLE or
OMAP_AUTO_UPDATE argument. As a result, exactly the same lower level
operations are performed, with addition of changing the lcdc.update_mode flag
to a value better suited for the controller state. This prevents any further
calls to disable_controller() from omap_lcdc_setup_plane() while the display
is suspended.

Created against linux-2.6.34-rc7.

14 years agoACPI / ACPICA: Use helper function for computing GPE masks

ACPI / ACPICA: Use helper function for computing GPE masks

In quite a few places ACPICA needs to compute a GPE enable mask with
only one bit, corresponding to a given GPE, set.  Currently, that
computation is always open coded which leads to unnecessary code
duplication.  Fix this by introducing a helper function for computing
one-bit GPE enable masks and using it where appropriate.

14 years agoACPI / ACPICA: Do not attempt to disable GPE when installing handler

ACPI / ACPICA: Do not attempt to disable GPE when installing handler

Commit 0f849d2cc6863c7874889ea60a871fb71399dd3f (ACPICA: Minimize
the differences between linux GPE code and ACPICA code base)
introduced a change attempting to disable a GPE before installing
a handler for it in acpi_install_gpe_handler() which was incorrect.
First, the GPE disabled by it is never enabled again (except during
resume) which leads to battery insert/remove events not being
reported on the Maxim Levitsky's machine.  Second, the disabled
GPE is still reported as enabled by the sysfs interface that only
checks its enable register's enable_for_run mask.

Revert this change for now, because it causes more damage to happen
than the bug it was supposed to fix.

kbuild: Fix modpost segfault

It just hit me.
It's the offset calculation in reloc_location() which overflows:
        return (void *)elf->hdr + sechdrs[section].sh_offset +
               (r->r_offset - sechdrs[section].sh_addr);

E.g. for the first rodata r entry:
r->r_offset < sechdrs[section].sh_addr
and the expression in the parenthesis produces 0xFFFFFFE0 or something
equally wise.

PCI: clear bridge resource range if BIOS assigned bad one

Yannick found that video does not work with 2.6.34.  The cause of this
bug was that the BIOS had assigned the wrong range to the PCI bridge
above the video device.  Before 2.6.34 the kernel would have shrunk
the size of the bridge window, but since
  d65245c PCI: don't shrink bridge resources
the kernel will avoid shrinking BIOS ranges.

So zero out the old range if we fail to claim it at boot time; this will
cause us to allocate a new range at startup, restoring the 2.6.34
behavior.

Fixes regression https://bugzilla.kernel.org/show_bug.cgi?id=16009.
