Events cannot be used between queues, they are fine grained synchronisation for the same queue. They can be used (with limitations) between the device and the host.
Would you like to add the configuration script "AX_PTHREAD" to your build specification?
Just downloaded the latest version of the project, now trying to run "autoreconf -i" throws a warning and an error:
aclocal: warning: couldn't open directory 'm4': No such file or directory
configure.ac:21: error: possibly undefined macro: AC_MSG_ERROR
If this token and others are legitimate, please use m4_pattern_allow.
See the Autoconf documentation.
autoreconf: /usr/bin/autoconf failed with exit status: 1
I've got this error in tut8:
Could not create graphics pipeline: Incomplete
Segmentation fault (core dumped)
All other tuts are working fine.
My system: Ubuntu 14.04, GeForce GTX 970, driver version 367.27
- If the memory is not host-coherent, then we need to flush application writes, invalidate application caches
- before reads, and insert memory barriers after device writes. For the sake of simplicity, as this tutorial
- is already huge, let's just ask for host-coherent memory. Such a memory may not be available on all
- devices, so ideally you would want to look for host-coherent memory, and if not found be prepared to do the
- above flushes, cache invalidations and barriers.
Even with coherent memory you must still insert the appropriate memory barriers after device writes (and indeed, before device reads (note: QueueSubmit effectively performs an implicit invalidate)).
All devices must support at least one memory type that is coherent.
Would you like to add more error handling for return values from the call of a function like "pthread_mutex_init"?
When I try to run the configure script, it works fine except for these three output lines:
checking vulkan/vulkan.h usability... no
checking vulkan/vulkan.h presence... no
checking for vulkan/vulkan.h... no
Then it exits with this message:
configure: error: Vulkan header not found
I downloaded the Vulkan SDK directly from LunarG, let the self-extracting archive do its thing and then followed the setup instructions in the Getting_Started.html file included in the SDK.
I set up my environment variables by adding these lines to my .bashrc file:
VULKAN_SDK=~/VulkanSDK/1.0.17.0/x86_64
export PATH=$PATH:$VULKAN_SDK/bin
export LD_LIBRARY_PATH=$VULKAN_SDK/lib
export VK_LAYER_PATH=$VULKAN_SDK/etc/explicit_layer.d
I've also tried copying "explicit_layer.d" directly into my "~/.local/share/vulkan/" directory and copying the "/vulkan/" directory that contains the header files directly into "/usr/include/". The former had no effect whatsoever, the latter removed the first two lines, but then threw an error that it couldn't find the Vulkan library.
I'm running Ubuntu 16.04 (4.4.0-28-generic), using an Nvidia GTX 760 with the proprietary drivers (version 364.16). I can confirm that Vulkan works on my system, I've ran "vulkaninfo" and tried "The Talos Principle".
I'm not sure what to do and while I'm fairly certain that I missed something obvious, I'm simply out of ideas... thanks in advance for any tips!
