AMD GART DRIVER

This mode is recommended for profiling specific work loads where you do not want clock or power gating for clock fluctuation to interfere with your results. TTM driver callback for dealing with vm faults. Setting 1 disables retry. Provides a simpler API for buffers that do not have any strict restrictions on where a buffer must be located. This is called when a shared DMA buffer no longer needs to be accessible by another device.

Writing to the file will attempt to upload a new powerplay table and re-initialize powerplay using that new table.

Enable or disable the sensors. See the driver output in the kernel log for the list of IPs on the asic. Replace existing mappings as we do so. Gart memory linearizes non-contiguous pages of system memory, allows GPU access system memory in a linezrized fashion. Set SI support driver. Sets up work functions for hotplug and reset interrupts, enables MSI functionality, initializes vblank, hotplug and reset interrupt handling. The default is the current set of stable display features.

Yeah, I get where you are coming from. Override VM update mode.

This should be called when a page fault has been handled. Pins the buffer object according to requested domain and zmd range. For coherent userptr handling registers an MMU notifier to inform the driver about updates on the page tables of a process. Default is HWS hardware scheduling with over-subscription. Set GPU scheduler timeout value in ms.

CONFIG_GART_IOMMU: Old AMD GART IOMMU support

But the GART has also been put to use by Linux kernel programmers to enable legacy bit PCI devices to access regions of system memory outside of their addressable range. To create a custom set of heuristics, write a string of numbers to the file starting with the number of the custom profile along with a setting for each heuristic parameter.

Set value 1 to enable emulation mode. Last edited by a moderator: Use this parameter to disable specific blocks. I understand your confusion, but it's not really all that confusing. When the profiling modes are selected, clock and power gating are disabled and the clocks are set for different profiling cases.

The default is 0 Disabled. Please check out our forum guidelines for info related to our community. Any one else remember that?

Send sigterm to HSA process on unhandled exceptions. So then please, don't call your newly invented vehicle wheter it is a car, a xmd, a motorcycle or a completely new thingVehicle.

This is used for recovering a buffer from its shadow in case of a gpu reset where vram context may be lost. Solaris17 Dainty Moderator Staff member. Default is not to send sigterm but just print errors on dmesg. The default is the current set of stable power features.

On older GPUs, the vbios provided a special power state for battery operation.

Add bo into the requested vm. Evicts all VRAM buffers on the lru list of the memory type. Notifies the driver we are taking a fault on this BO and have reserved it, also performs bookkeeping.
