similar to: [PATCH drm-next v6 02/13] drm: manager to keep track of GPUs VA mappings

Add infrastructure to keep track of GPU virtual address (VA) mappings with a decicated VA space manager implementation. New UAPIs, motivated by Vulkan sparse memory bindings graphics drivers start implementing, allow userspace applications to request multiple and arbitrary GPU VA mappings of buffer objects. The DRM GPU VA manager is intended to serve the following purposes in this context. 1)

There is no requirement to disable pagefaults and preemption for these cache management mappings. Replace kmap_atomic_pfn() with kmap_local_pfn(). This allows to remove kmap_atomic_pfn() in the next step.

Hi, Can any one help me? I''m using Ubuntu and trying to connect to an oracle database using oracle_enhanced adapter connection, but keeps getting following error: /usr/lib/ruby/gems/1.8/gems/activesupport-2.1.0/lib/active_support/dependencies. rb:275:in `load_missing_constant'': uninitialized constant ActiveRecord::Connecti onAdapters::OracleEnhancedAdapter (NameError)

Hi, I just downloaded the latest rails, and tried to run webrick. I get this strange set of error messages. It looks like the real error is NameError: cannot remove Object::UnknownPropertyMethod I never had this problem with older versions, and the ''fastcgi'' variant, running under lighttpd runs fine. Any ideas why webrick appears to be broken? Thanks, David

Hi Danilo, The below part of the documentation is out of date now.

A new intel-gpu-tools quarterly release is available with the following changes: - New frequency manipulation tool (intel_gpu_frequency) - Adjustments for the Solaris port (Alan Coopersmith). - Remove tests/NAMING-CONVENTION since it's all in the docbook now, to avoid divergent conventions. - New CRITICAL log level for really serious stuff (Thomas Wood). - Interactive test mode can now

So far the DRM GPUVA manager offers common infrastructure to track GPU VA allocations and mappings, generically connect GPU VA mappings to their backing buffers and perform more complex mapping operations on the GPU VA space. However, there are more design patterns commonly used by drivers, which can potentially be generalized in order to make the DRM GPUVA manager represent a basic GPU-VM

I am a total newbie to Rails and Ruby. I have the Agile Web Development with Rails book and am following through the first few chapters. I got to the "Creating you own Rails API Documentation" and followed the following steps. rails dummy_app cd dummy_app Then when I run the "rake rails:freeze:gems" command I get the following error. No rails gem 3.0.5.001 is installed. Do

nouveau_abi16_ioctl_channel_alloc() and nouveau_cli_init() simply call their corresponding *_fini() counterpart. This can lead to nouveau_sched_fini() being called without struct nouveau_sched ever being initialized in the first place. Instead of embedding struct nouveau_sched into struct nouveau_cli and struct nouveau_chan_abi16, allocate struct nouveau_sched separately, such that we can check

A new igt-gpu-tools release is available with the following changes: - Meson build options have been renamed. Please check the news options in meson_options.txt and make sure you don't get any warnings when configuring the project. (Simon Ser) - Compile-testing CI for MIPS. (Guillaume Tucker) - Various igt_runner reliability improvements (Petri Latvala & Arkadiusz Hiler) - Switched

Can anyone provide some expert debugging help here? What''s the first step to take to see what the issue is here? I have no errors in the rails app''s log files. The only errors I have are those provided by apache and they are: ''FastCGI: Incomplete headers (0) bytes received from server'' I''ve tried editing the shebang line, removing line feeds, but

Hello all, The topic of plugin dependencies has come up before and it doesn''t seem to have been addressed by core or core doesn''t seem to think it''s an issue. I''ve looked at the current edge code and don''t see anything new, so if I''ve missed something *please* let me know. The following article makes mention of a require_plugin
