Hi Thierry,
I love your patch! Yet something to improve:
[auto build test ERROR on linus/master]
[also build test ERROR on v5.4-rc5 next-20191031]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to spec

So this is not causing any problems, I suppose it's controlling the hardware by
reading/writing to memory addresses provided by the kernel, and valgrind is
giving a false positive, thank you for your rapid

--- Comment #1 from Ilia Mirkin ---
This is expected. valgrind does not understand how the ioctl works, so it
thinks that uninitialized memory is being read. But that's not an actual issue.

When the GPU powergate is controlled by a generic power domain provider,
the reset will automatically be asserted and deasserted as part of the
power-ungating procedure.

When Nouveau is instantiated on top of a platform device, the dev->pdev
field will be NULL and calling pci_disable_device() will crash. Move the
PCI disabling code to the PCI specific driver removal code.

The GPUs found on Tegra SoCs have registers that can be used to read the
WPR configuration. Use these registers instead of reaching into the
memory controller's register space to read the same information.

This dummy implementation is useful to avoid a dependency on the
IOMMU_API Kconfig symbol in drivers that can optionally use the IOMMU
API.
In order to fully use this, also move the struct iommu_fwspec definition
out of the IOMMU_API protected region.

Hi Ben,
here's a revised subset of the patches I had sent out a couple of weeks
ago. I've reworked the BAR2 accesses in the way that you had suggested,
which at least for GP10B turned out to be fairly trivial to do. I have
not looked in detail at this for GV11B yet, but a cu

gp10b uses the new engine enumeration mechanism introduced in the Pascal
architecture. As a result, the copy engine, which used to be at index 2
for prior Tegra GPU instantiations, has now moved to index 0. Fix up the
index and also use the gp100 variant of the copy engine cl
From: Thierry Reding
There are extra registers that need to be programmed to make the level 2
cache work on GP10B, such as the stream ID register that is used when an
SMMU is used to translate memory addresses.

There is no BAR2 on GP10B and there is no need to map through BAR2
because all memory is shared between the GPU and the CPU. Add a custom
