arg is long int, so arg = (arg << 22) >> 22 makes the upper 22 bits of arg equal to bit 9 (or bit 41). But we then mask away all but bits 0-9, so this is entirely redundant. Signed-off-by:

This change is needed to properly lock I2C bus device and driver, which serve DDC lines. Without this change I2C bus driver module may gone in runtime and this won't be noticed by the driver. Signed-off-by:

The commit 53bdcf5f ("drm: sti: fix sub-components bind") moves i2c adapter search and locking from .bind() to .probe(), however proper error path in the modified .probe() is not implemented and leftover of the related error path in .bind() remains. This change fixes these issues. Fixes: 53bdcf5f ("drm: sti: fix sub-components bind") Signed-off-by:

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:
