* drm/radeon: add spinlocks for indirect register accesssAlex Deucher2013-09-11
| | | | | | | | | This adds spinlocks to protect access to other indirect register apertures. These indirect spaces are used pretty infrequently and we haven't had an reported problems, but better safe than sorry. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
* drm/radeon: protect concurrent smc register access with a spinlockAlex Deucher2013-09-11

* | gpu/vga_switcheroo: add driver control power feature. (v3)Dave Airlie2013-08-28
|/ | | | | | | | | | | | | | | | | | | | | | | | | | For optimus and powerxpress muxless we really want the GPU driver deciding when to power up/down the GPU, not userspace. This adds the ability for a driver to dynamically power up/down the GPU and remove the switcheroo from controlling it, the switcheroo reports the dynamic state to userspace also. It also adds 2 power domains, one for machine where the power switch is controlled outside the GPU D3 state, so the powerdown ordering is done correctly, and the second for the hdmi audio device to make sure it can resume for PCI config space accesses. v1.1: fix build with switcheroo off v2: add power domain support for radeon and v1 nvidia dsms v2.1: fix typo in off case v3: add audio power domain for hdmi audio + misc audio fixes v4: use PCI_SLOT macro, drop power reference on hdmi audio resume failure also.

* | efi: Make 'efi_enabled' a function to query EFI facilitiesMatt Fleming2013-01-30
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Originally 'efi_enabled' indicated whether a kernel was booted from EFI firmware. Over time its semantics have changed, and it now indicates whether or not we are booted on an EFI machine with bit-native firmware, e.g. 64-bit kernel with 64-bit firmware. The immediate motivation for this patch is the bug report at, https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557 which details how running a platform driver on an EFI machine that is designed to run under BIOS can cause the machine to become bricked. Also, the following report, https://bugzilla.kernel.org/show_bug.cgi?id=47121 details how running said driver can also cause Machine Check Exceptions. Drivers need a new means of detecting whether they're running on an EFI machine, as sadly the expression, if (!efi_enabled) hasn't been a sufficient condition for quite some time. Users actually want to query 'efi_enabled' for different reasons - what they really want access to is the list of available EFI facilities. For instance, the x86 reboot code needs to know whether it can invoke the ResetSystem() function provided by the EFI runtime services, while the ACPI OSL code wants to know whether the EFI config tables were mapped successfully. There are also checks in some of the platform driver code to simply see if they're running on an EFI machine (which would make it a bad idea to do BIOS-y things). This patch is a prereq for the samsung-laptop fix patch.

* drm/radeon: add quirk for d3 delay during switcheroo poweron for apple macbooksMaarten Lankhorst2013-01-07
| | | | | | | | | | | | | | | | | | | vga-switcheroo with apple-gmux does not switch correctly on my system. The PCI configuration space is not restored correctly, resulting in MSI not working after switch. Only useful item in dmesg is: [ 33.922807] radeon 0000:01:00.0: Refused to change power state, currently in D3 I did some testing, dumping the difference in ms between first succesful switch from D3 to D0, and it seems that there is slightly more than 20 ms difference when the device is re-enabled through vga-switcheroo. So bump the re-enable d3 delay to 20 ms to handle this, which fixes msi not working on my system after switcheroo-ing. Default d3_delay value is PCI_PM_D3_WAIT, 10 ms.
