This patch uses an approach closer to the nvidia driver to configure both PLLs for high gddr5 memory clocks (usually above 2400MHz) Previously nouveau used the one PLL as it was used for the lower clocks and just adjusted the second PLL to get as close as possible to the requested clock. This means for my card, that I got a 4050 MHz clock although 4008 MHz was requested. Now the driver iterates over a list of PLL configuration also used by the nvidia driver and then adjust the second PLL to get near the requested clock. Also it hold to some restriction I found while analyzing the PLL configurations This won't fix all gddr5 high clock issues itself, but it should be fine on hybrid gpu systems as found on many laptops these days. Also switching while normal desktop usage should be a lot more stable than before. v2: move the pll code into ramgk104 Signed-off-by:

10053c is not even read on some cards, and I have no idea exactly what the criteria are. Likely NVIDIA pre-scans the VBIOS and in their driver disables all features that are never used. The practical effect should be the same as this implementation though. Signed-off-by:

If the hardware supports extended tag field (8-bit ones), then enable it. This is usually done by the VBIOS, but not on some MBPs (see fdo#86537). In case extended tag field is not supported, 5-bit tag field is used which limits the possible number of requests to 32. Apparently bits 7:0 of 0x08841c stores some number of outstanding requests, so cap it to 32 if extended tag is unsupported. Fixes: fdo#86537 v2: Restrict changes to chipsets >= 0x84 v3: * Add nvkm_pci_mask to pci.h * Mask bit 8 before setting it v4: * Rename `add` argument of nvkm_pci_mask to `value` * Move code from nvkm_pci_init to g84_pci_init and remove PCIe and chipset checks v5: * Rebase code on latest PCI structure * Restore PCIe check * Fix namings in nvkm_pci_mask * Rephrase part of the commit message Signed-off-by: -

Increase clock timeout of some unknown engines in order to avoid failure at high gpcclk rate. This fixes IBUS read faults on my GF119 when reclocking is manually enabled. Note that memory reclocking is completely broken and NvMemExec has to be disabled to allow core clock reclocking only. Signed-off-by:

I got confirmation that we can read and change the voltage with the same code. The divider is also computed correctly on the gm204 we got our hands on. Thanks to Yoshimo on IRC for executing the tests on his gm204! Signed-off-by:

Most Keplers actually use the GPIO-based voltage management instead of the new PWM-based one. Use the GPIO mode as a fallback as it already gracefully handles the case where no GPIOs exist. All the Maxwells seem to use the PWM method though. v2: - Do not forget to commit the PWM configuration change! Signed-off-by: -

So far the DMA mask was not set for platform devices, which limited them to a 32-bit physical space. Allow dma_set_mask() to be called for non-PCI devices, and also take the IOMMU bit into account since it could restrict the physically addressable space. Signed-off-by:

The Great Nouveau Refactoring Take II brought us a lot of goodness, including acquire/release methods that are called before and after an instobj is modified. These functions can be used as synchronization points to manage CPU/GPU coherency if we modify an instobj using the CPU. This patch replaces the legacy and slow PRAMIN access for gk20a instmem with CPU mappings and writes. A LRU list is used to unmap unused mappings after a certain threshold (currently 1MB) of mapped instobjs is reached. This allows mappings to be reused most of the time. Accessing instobjs using the CPU requires to maintain the GPU L2 cache, which we do in the acquire/release functions. This triggers a lot of L2 flushes/invalidates, but most of them are performed on an empty cache (and thus return immediately), and overall context setup performance greatly benefits from this (from 250ms to 160ms on Jetson TK1 for a simple libdrm program). Making L2 management more explicit should allow us to grab some more performance in the future. Signed-off-by:
