Is it just a means to increase memory bandwidth another bit? When auto is selected, the driver will attempt to dynamically select the optimal power profile for current conditions in the driver. The default is Return 0 for success or a negative error code on failure. On older GPUs, the vbios provided a special power state for balanced operation. On older GPUs, the vbios provided a special power state for performance operation. The default is 0 depending on gfx.

If the memory is unbound gart memory, binds the pages into gart table.

The default is the current set of stable display features. Set value 0 to disable it. Is it just a means to increase memory bandwidth another bit?

The default akd 2. Joined Aug 11, Messages 0. Last edited by a moderator: For CIK asic, when radeon driver is enabled, set value 0 to use radeon driver, while set value 1 to use amdgpu driver.

Solaris17 Dainty Moderator Staff member. The userspace drivers maintain their own address space and the kernel sets up their pages tables accordingly when they submit their command buffers and a VMID is assigned. Desired fan speed Unit: Set value 1 to enable emulation mode.

For coherent userptr handling registers an MMU notifier to inform the driver about updates on the page tables of a process. Writing to the file will attempt to upload a new powerplay table and re-initialize powerplay using that new table. The default is 0xffffffff enable all blocks on a device. The default is using radeon driver when it available, otherwise using amdgpu driver.

Set SI support driver. The Linux Kernel 4.

This is called when a shared DMA buffer no longer needs to be accessible by another device. Tears down work functions for hotplug and reset interrupts, disables MSI amdd, shuts down vblank, hotplug and reset interrupt handling, turns off interrupts from all sources all ASICs.

The amdgpu driver provides a sysfs API for gaet new powerplay tables. This is the hotplug event work handler all ASICs. Return current GPU offset of the object. 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.

The amdgpu driver provides a sysfs API for adjusting what power levels are enabled for a given power state. This is only needed when running on an emulator. It’s not AMD’s fault, nor yours. Callback from IH ring processing to handle the entry at the current position and advance the read pointer. Override power features enabled. Default value, 0, enables retry.

Benetanegia New Member Dec 8, Used by GEM ioctl or kernel driver to set the tiling flags on a buffer.

It decouples compute pasid from vm. You just can’t say that, just like you can’t say that vehicles are more capable than cars. This is garg longer provided on newer GPUs so the option does nothing in that case. Set 1 to enable Deep Color support. The index should be 0 if to set minimum clock.
