* hwmon: Provide managed hwmon registrationGuenter Roeck2013-10-141-0/+63
| | | | | | | | | | | Drivers using the new hwmon_device_register_with_groups API often have a remove function which consists solely of a call hwmon_device_unregister(). Provide support for devm_hwmon_device_register_with_groups and devm_hwmon_device_unregister to allow this repeated code to be removed and help eliminate error handling code.

* hwmon: Introduce hwmon_device_register_with_groupsGuenter Roeck2013-10-141-16/+106
| | | | | | | | | | hwmon_device_register_with_groups() lets callers register a hwmon device together with all sysfs attributes in a single call. When using hwmon_device_register_with_groups(), hwmon attributes are attached to the hwmon device directly and no longer with its parent device. Signed-off-by: Guenter Roeck <linux@roeck-us.net>

Now, all architectures are supposed to build fine when MSI support is enabled: instead of having the architecture tell *when* MSI support can be used, it's up to the architecture code to ensure that MSI support can be enabled. On x86, commit ebd97be635 removed the following line: select ARCH_SUPPORTS_MSI if (X86_LOCAL_APIC && X86_IO_APIC) Which meant that MSI support was only available when the local APIC and I/O APIC were enabled. While this is always true on SMP or x86-64, it is not necessarily the case on i386 !SMP. The below patch makes sure that the local APIC and I/O APIC support is always enabled when MSI support is enabled. To do so, it: * Ensures the X86_UP_APIC option is not visible when PCI_MSI is enabled. This is the option that allows, on UP machines, to enable or not the APIC support. It is already not visible on SMP systems, or x86-64 systems, for example. We're simply also making it invisible on i386 MSI systems. * Ensures that the X86_LOCAL_APIC and X86_IO_APIC options are 'y' when PCI_MSI is enabled. Notice that this change requires a change in drivers/iommu/Kconfig to avoid a recursive Kconfig dependencey. The AMD_IOMMU option selects PCI_MSI, but was depending on X86_IO_APIC. This dependency is no longer needed: as soon as PCI_MSI is selected, the presence of X86_IO_APIC is guaranteed. Moreover, the AMD_IOMMU already depended on X86_64, which already guaranteed that X86_IO_APIC was enabled, so this dependency was anyway redundant.

It seems Intel hw designers decided that was too nice a facility to allow us to have so they removed it when they went on-die (so since Ironlake at least). Now Alex Williamson added support for VGA arbitration for newer GPUs however this now exposes itself to userspace as requireing arbitration of GPU VGA regions and the X server gets involved and disables things that it can't handle when VGA access is possibly required around every operation. So in order to not break userspace we just reverted things back to the old known broken status so maybe we can try and design out way out.

Adding drm/i915 into the vga arbiter chain means that X (in a piece of well-meant paranoia) will do a get/put on the vga decoding around _every_ accel call down into the ddx. Which results in some nice performance disasters [1]. This really breaks userspace, by disabling DRI for everyone, and stops OpenGL from working, this isn't limited to just the i915 but both the integrated and discrete GPUs on multi-gpu systems, in other words this causes untold worlds of pain, Ville tried to come up with a Great Hack to fiddle the required VGA I/O ops behind everyone's back using stop_machine, but that didn't really work out [2]. Given that we're fairly late in the -rc stage for such games let's just revert this all. One thing we might want to keep is to delay the disabling of the vga decoding until the fbdev emulation and the fbcon screen is set up. If we kill vga mem decoding beforehand fbcon can end up with a white square in the top-left corner it tried to save from the vga memory for a seamless transition. And we have bug reports on older platforms which seem to match these symptoms. But again that's something to play around with in -next.
