Fixes commit 42ddb453 ("radeon: Conditionally compile PM code") Before the above mentioned patch, codes between the line number 547 and 2803 were already inside "#ifdef CONFIG_PM" container. Thus, addition of "#if defined(CONFIG_PM)" was not required in the patch. It also affected the "#ifdef CONFIG_PPC_OF" container (line 1943-2510). From the current snapshot of radeon_pm.c, remove: 1434 | #if defined(CONFIG_PM) and, 2213 | #endif This removes the redundant CONFIG_PM directive as well as fixes the CONFIG_PPC (earlier CONFIG_PPC_OF) container.

The only in-tree user for mbx driver for Intel 2700G graphics chip was cm-x270 platform. Since this platform was removed by the commit 9d323914 ("ARM: pxa: remove Compulab pxa2xx boards") there is no point to keep the obsolete framebuffer driver. Signed-off-by:

Drivers should do only device-specific jobs. But in general, drivers using legacy PCI PM framework for .suspend()/.resume() have to manage many PCI PM-related tasks themselves which can be done by PCI Core itself. This brings extra load on the driver and it directly calls PCI helper functions to handle them. Switch to the new generic framework by updating function signatures and define a "struct dev_pm_ops" variable to bind PM callbacks. Also, remove unnecessary calls to the PCI Helper functions along with the legacy .suspend & .resume bindings. The ark_pci_suspend() is not designed to function in the case of Freeze. Thus, the code checked for "if (state.event == PM_EVENT_FREEZE....)". This is because, in the legacy framework, this callback was invoked even in the event of Freeze. Hence, added the load of unnecessary function-call. The goal can be achieved by binding the callback with only ".suspend" and ".poweroff" in the "ark_pci_pm_ops" const variable. This also avoids the step of checking "state.event == PM_EVENT_FREEZE" every time the callback is invoked. Signed-off-by:

This patch implements the necessary functions to add writeback support for vkms. This feature is useful for testing compositors if you don't have hardware with writeback support. Change in V4 (Emil and Melissa): - Move signal completion above drm_crtc_add_crc_entry() - Make writeback always available - Use appropriate namespace - Drop fb check in vkms_wb_atomic_commit - Make vkms_set_composer visible for writeback code - Enable composer operation on prepare_job and disable it on cleanup_job - Drop extra space at the end of the file - Rebase Change in V3 (Daniel): - If writeback is enabled, compose everything into the writeback buffer instead of CRC private buffer - Guarantees that the CRC will match exactly what we have in the writeback buffer. Change in V2: - Rework signal completion (Brian) - Integrates writeback with active_planes (Daniel) - Compose cursor (Daniel) Signed-off-by:
