Changes since v3: - Use a single dma_attr for all DMA-API allocations in instmem instead of one per allocation - Use device.info.ram_size instead of pfb->ram to check whether VRAM is present outside of nvkm Changes since v2: - Cleaner changes for ltc - Fixed typos in gk20a instmem IOMMU comments Changes since v1: - Add missing else condition in ltc - Remove extra flags that slipped into

A series I have waited too long to submit, and the recent refactoring made me pay the price of my perfectionism, so here are the features that are at least completed Patches 1-3 make the presence of a RAM device optional, and remove GK20A's dummy RAM driver we were using so far. On chips using shared memory, such a device can confuse the driver into moving objects where there is no need to,

Hi, Generally the the imported buffers which has memory type TTM_PL_TT are mapped as small pages probably due to lack of big page allocation. But the platform device which also use memory type TTM_PL_TT, like GK20A, can *allocate* big page though the IOMMU hardware inside the SoC. This is a try to map the imported buffers as big pages in GMMU by the platform IOMMU. With some preparation work to

Looks like it''s time for another release of Radiant: http://radiantcms.org/download/ Radiant 0.6.8 "Incise" adds a number of new features that enhance support for extensions and completes the project''s move to github. Of special note are: * Extension installer/uninstaller scripts (script/extension) and a global ''extension registry'' at

Been trying to build the trunk to test some things for about a week now using VS8 (VS2k5). Tons of Warnings (like things first being declared struct, being redefined class and so forth, those need to be fixed, but are otherwise not harmful), and a *lot* of errors. Being trunk I figured just the normal trunk-type issues, but it has been going on for a while now, so figured it would be good to

The KVM introspection subsystem provides a facility for applications running on the host or in a separate VM, to control the execution of other VM-s (pause, resume, shutdown), query the state of the vCPUs (GPRs, MSRs etc.), alter the page access bits in the shadow page tables (only for the hardware backed ones, eg. Intel's EPT) and receive notifications when events of interest have taken place
