| | | | | | | | | | These files didn't exist at the time of the module.h split, and so were not fixed by the commits on that baseline. Since they use the EXPORT_SYMBOL and/or THIS_MODULE macros, they will need the new export.h file included that provides them.

| | * | | cpuidle: Single/Global registration of idle statesDeepthi Dharwar2011-11-0616-207/+439

The statistics needed on per-cpu basis by the governor are kept per-cpu. This simplifies the cpuidle subsystem as state registration is done by single cpu only. Having single copy of cpuidle_states saves memory. Rare case of asymmetric C-states can be handled within the cpuidle driver and architectures such as POWER do not have asymmetric C-states. Having single/global registration of all the idle states, dynamic C-state transitions on x86 are handled by the boot cpu. Here, the boot cpu would disable all the devices, re-populate the states and later enable all the devices, irrespective of the cpu that would receive the notification first.

State demotion is now handled by the driver and it returns the actual state entered. Hence, this mechanism is not required. Also this removes per-cpu flags from cpuidle_state enabling it to be made global.

The actual entered state may be different because of software or hardware demotion. Software demotion is done by the back-end cpuidle driver and can be accounted correctly. Current cpuidle code uses last_state field to capture the actual state entered and based on that updates the statistics for the state entered. Ideally the driver enter routine should update the counters, and it should return the state actually entered rather than the time spent there. The generic cpuidle code should simply handle where the counters live in the sysfs namespace, not updating the counters.

As the "pnp_xxx" structs are not designed to cope with IORESOURCE_DISABLED, and hence no code can test for this value, setting this value is actually a "no op" and can be skipped altogether. It is sufficient to remove the checks for "empty" resources and continue processing. The patch is applied against 3.1.

In function acpi_hw_clear_acpi_status, acpi_os_acquire_lock holds the lock acpi_gbl_hardware_lock before calling acpi_hw_register_write(), then without releasing acpi_gbl_hardware_lock, this function calls acpi_ev_walk_gpe_list, which tries to hold acpi_gbl_gpe_lock. Both acpi_gbl_hardware_lock and acpi_gbl_gpe_lock are at same lock-class and which might cause lock recursion deadlock. Following patch fixes this scenario by just releasing acpi_gbl_hardware_lock before calling acpi_ev_walk_gpe_list.

| * | | vmwgfx: Reinstate the update_layout ioctlThomas Hellstrom2011-11-025-31/+107
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to redefine a connector as "connected" if it matches a window in the host preferred GUI layout. Otherwise "smart" window managers would turn on Xorg outputs that we don't want to be on. This reinstates the update_layout and adds the following information to the modesetting system. a) Connection status <-> Equivalent to real hardware connection status b) Preferred mode <-> Equivalent to real hardware reading EDID c) Host window position <-> Equivalent to a real hardware scanout address dynamic register. It should be noted that there is no assumption here about what should be displayed and where. Only how to access the host windows. This also bumps minor to signal availability of the new IOCTL.

| * | | drm/radeon/kms: always do extended edid probeAlex Deucher2011-11-013-85/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rather than having a quirk list just always check the EDID header when probing. This is the recommended behavior according to the display team. This avoids problems with improperly terminated i2c lines on some boards. This is also what the proprietary driver does.

| * | | drm/radeon/kms: remove useless radeon_ddc_dump()Alex Deucher2011-11-011-33/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function didn't work with DP, eDP, or DP bridge connectors and thus confused users as it lead them to believe nothing was connected or the EDID was invalid when in fact is was, just on the aux bus rather an i2c. It should also speed up module loading as it avoids a bunch of extra DDC probing. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

| * | | drm/radeon/kms: allocate vram scratch page on 6xx+Alex Deucher2011-11-015-57/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The vram scratch was originally only used on some 7xx asics to work around a hw bug. Allocate the scratch page on all 6xx+ radeons and set the MC_VM_SYSTEM_APERTURE_DEFAULT_ADDR to point to it. We shouldn't ever hit it since we limit the system aperture to vram or vram and AGP, but better safe than sorry.
