| * x86/agp: Fix agp_amd64_init and agp_amd64_cleanupFUJITA Tomonori2010-01-131-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes the regression introduced by the commit f405d2c02395a74d3883bd03ded36457aa3697ad. The above commit fixes the following issue: http://marc.info/?l=linux-kernel&m=126192729110083&w=2 However, it doesn't work properly when you remove and insert the agp_amd64 module again. agp_amd64_init() and agp_amd64_cleanup should be called only when gart_iommu is not called earlier (that is, the GART IOMMU is not enabled). We need to use 'gart_iommu_aperture' to see if GART IOMMU is enabled or not.

* | revert "drivers/video/s3c-fb.c: fix clock setting for Samsung SoC Framebuffer"Mark Brown2010-01-161-6/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix divide by zero and broken output. Commit 600ce1a0fa ("fix clock setting for Samsung SoC Framebuffer") introduced a mandatory refresh parameter to the platform data for the S3C framebuffer but did not introduce any validation code, causing existing platforms (none of which have refresh set) to divide by zero whenever the framebuffer is configured, generating warnings and unusable output. Ben Dooks noted several problems with the patch: - The platform data supplies the pixclk directly and should already have taken care of the refresh rate. - The addition of a window ID parameter doesn't help since only the root framebuffer can control the pixclk. - pixclk is specified in picoseconds (rather than Hz) as the patch assumed. and suggests reverting the commit so do that. Without fixing this no mainline user of the driver will produce output.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many platform support this feature, and it can provide significant power savings when the reduced refresh rate is low. However, on some platforms a secondary (reduced) timing is provided but not actually supported by the hardware. This results in undesirable flicker at runtime. So disable the feature by default, but allow users to opt-in to the reduced clock behavior with a new module parameter, lvds_downclock, that can be set to 1 to enable the feature.

| * | drm/i915: Don't wait interruptible for possible plane buffer flushZhenyu Wang2010-01-123-1/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we setup buffer for display plane, we'll check any pending required GPU flush and possible make interruptible wait for flush complete. But that wait would be most possibly to fail in case of signals received for X process, which will then fail modeset process and put display engine in unconsistent state. The result could be blank screen or CPU hang, and DDX driver would always turn on outputs DPMS after whatever modeset fails or not. So this one creates new helper for setup display plane buffer, and when needing flush using uninterruptible wait for that. This one should fix bug like https://bugs.freedesktop.org/show_bug.cgi?id=24009. Also fixing mode switch stress test on Ironlake.

From the SDVO spec once when another I2C transaction is finished after completing the I2C transaction of issuing the bus switch command, it will be switched back to the SDVO internal state again. So we can't initiate a new I2C transaction to read the response after issuing the DDC bus switch command. Instead we should issue DDC bus switch command and read the response in the same I2C transaction. https://bugs.freedesktop.org/show_bug.cgi?id=23842 https://bugs.freedesktop.org/show_bug.cgi?id=24458 https://bugs.freedesktop.org/show_bug.cgi?id=24522 https://bugs.freedesktop.org/show_bug.cgi?id=24282 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Tested-by: Sebastien Caty <sebastien.caty@mrnf.gouv.qc.ca> Signed-off-by: Eric Anholt <eric@anholt.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For any given clock we can use the find_pll to get the corresponding DPLL setting. It is unnecessary to use the find_reduce_pll callback function to calculate the DPLL parameter for LVDS downclock in order to get the same divider factor(P) for the normal and downclock. In theory when the LVDS downclock is supported by LVDS panel, we should get the same DPLL divider factor(P) for the normal clock and reduced downclock. If we get the diferent divider factor(P) for normal clock and reduced downclock, it means that the found downclock is incorrect and should be discarded. So we should use find_pll callback to calculate the DPLL parameter for the LVDS reduced downclock as for the normal clock. Then we can do the cleanup about find_reduced_pll.

| * | | | Input: add compat support for sysfs and /proc capabilities outputDmitry Torokhov2010-01-121-15/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Input core displays capabilities bitmasks in form of one or more longs printed in hex form and separated by spaces. Unfortunately it does not work well for 32-bit applications running on 64-bit kernels since applications expect that number is "worth" only 32 bits when kernel advances by 64 bits. Fix that by ensuring that output produced for compat tasks uses 32-bit units. Reported-and-tested-by: Michael Tokarev <mjt@tls.msk.ru> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

During probe, psmouse_switch_protocol() calls psmouse_extensions() with set_properties=1. This calls the dummy synaptics_init() which returns an error code, instructing us not to use the synaptics extensions. During resume, psmouse_reconnect() calls psmouse_extensions() with set_properties=0, in which case call to synaptics_init() is bypassed and PSMOUSE_SYNAPTICS is returned. Since the result is different from previous attempt psmouse_reconnect() fails and full re-probe happens. Fix this by tweaking the set_properties=0 codepath in psmouse_extensions() to be more careful about offering PSMOUSE_SYNAPTICS extensions.

This is unfortunate, because (for example) keyboard presses are three events: key, msc scancode, and syn. They'll be enqueued fast enough in kernel space that all three events will be ready to read by the time userspace runs, so the first invocation of the signal handler will read all three events, but then the second two invocations still have to run to do no work. Instead, only send the SIGIO notification on syn events. This is a slight abuse of SIGIO semantics, in principle it ought to fire as soon as any events are readable. But it matches evdev semantics, which is more important since SIGIO is rather vaguely defined to begin with.

In fact, attempts to take serio->drv_mutex in attribute methods may lead to the following deadlock: sysfs_read_file() fill_read_buffer() sysfs_get_active_two() psmouse_attr_show_helper() serio_pin_driver() serio_disconnect_driver() mutex_lock(&serio->drv_mutex); <--------> mutex_lock(&serio_drv_mutex); psmouse_disconnect() sysfs_remove_group(... psmouse_attr_group); .... sysfs_deactivate(); wait_for_completion(); Fix this by removing calls to serio_[un]pin_driver() and functions themselves and using driver-private mutexes to serialize access to attribute's set() methods that may change device state.
