So in a lot of modern systems, a GPU will always be below a parent bridge that won't share with any other GPUs. This means VGA arbitration on those GPUs can be controlled by using the bridge routing instead of io/mem decodes. The problem is locating which GPUs share which upstream bridges. This patch attempts to identify all the GPUs which can be controlled via bridges, and ones that can't. This patch endeavours to work out the bridge sharing semantics. When disabling GPUs via a bridge, it doesn't do irq callbacks or touch the io/mem decodes for the gpu.

However, on rc6 disabling, the lock is held by the caller. Rearranged the locking so that it's safe in both cases.

This is to address special requirements for gen6 (SNB) reads and writes. Registers in the range 0-0x40000 on gen6 platforms require special handling. Instead of relying on the callers to pick the registers correctly, move the logic into the read and write functions.

This patch addresses those cases, so that the function returns the correct frequency. When the shader pll is disabled, the blob reports 2*core clock Whereas for memory, the data stored in the vbios. This action is incorrect as some vbioses store a clock value that is less than the refference clock of the pll.

This is because though g4x and ironlake share the same bsd_ring, their interrupt control interfaces have _two_ differences. 1.different irq enable/disable functions: On g4x are i915_enable_irq and i915_disable_irq. On ironlake are ironlake_enable_irq and ironlake_disable_irq. 2.different irq flag: On g4x user interrupt flag in BSD ring on is I915_BSD_USER_INTERRUPT. On ironlake is GT_BSD_USER_INTERRUPT Old bsd_ring_get/put_irq call ring_get_irq and ring_get_irq. ring_get_irq and ring_put_irq only call ironlake_enable/disable_irq. So comes the irq miss on g4x. To fix this, as other rings' code do, conditionally call different functions(i915_enable/disable_irq and ironlake_enable/disable_irq) and use different interrupt flags in bsd_ring_get/put_irq.

Under certain configurations, the i2c-adapter functionality is queried during initialisation and so may trigger an OOPS during boot. Hence, we need to reorder the initialisation of the ddc proxy until after we hook up the i2c adapter for the SDVO device. The condition under which it fails is when the i2c_add_adapter calls into i2c_detect which will attempt to probe all valid addresses on the adapter iff there is a pre-existing i2c_driver with the same class as the freshly added i2c_adapter. So it appears to depend upon having compiled in (or loaded such a module before i915.ko) an i2c-driver that likes to futz over the i2c_adapters claiming DDC support.
