* mesa: if MESA_DEBUG=context, create a debug contextBrian Paul2016-11-163-2/+25
| | | | | | | | | | | | | | | | | | | A number of drivers report useful debug/perf information accessible through GL_ARB_debug_output and with debug contexts (i.e. setting the GLX_CONTEXT_DEBUG_BIT_ARB flag). But few applications actually use the GL_ARB_debug_output extension. This change lets one set the MESA_DEBUG env var to "context" to force-set a debug context and report debug/perf messages to stderr (or whatever file MESA_LOG_FILE is set to). This is a useful debugging tool. The small change in st_api_create_context() is needed so that st_update_debug_callback() gets called to hook up the driver debug callbacks when ST_CONTEXT_FLAG_DEBUG was not set, but MESA_DEBUG=context. v2: use %.*s format string instead of allocating temporary buffer.

* Fix races during _mesa_HashWalk().Steinar H. Gunderson2016-11-121-11/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is currently no protection against walking a hash (using _mesa_HashWalk()) and modifying it at the same time, for instance by inserting or deleting elements. This leads to segfaults in multithreaded code if e.g. someone calls glTexImage2D (which may have to walk the list of FBOs) while another thread is calling glDeleteFramebuffers on another thread with the two contexts sharing lists. The reason for this is that _mesa_HashWalk() doesn't actually take the mutex that normally protects the hash; it takes an entirely different mutex. Thus, walks are only protected against other walks, and there is also no outer lock taking this. There is an old comment saying that this is to fix problems with deadlock if the callback needs to take a mutex; we solve this by changing the mutex to be recursive.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a problem seen with gallium drivers vs android wallpaper. Basically, what happens is: EGLSurface tmpSurface = mEgl.eglCreatePbufferSurface(mEglDisplay, mEglConfig, attribs); mEgl.eglMakeCurrent(mEglDisplay, tmpSurface, tmpSurface, mEglContext); int[] maxSize = new int[1]; Rect frame = surfaceHolder.getSurfaceFrame(); glGetIntegerv(GL_MAX_TEXTURE_SIZE, maxSize, 0); mEgl.eglMakeCurrent(mEglDisplay, EGL_NO_SURFACE, EGL_NO_SURFACE, EGL_NO_CONTEXT); mEgl.eglDestroySurface(mEglDisplay, tmpSurface); ... check maxSize vs frame size and bail if needed ... mEglSurface = mEgl.eglCreateWindowSurface(mEglDisplay, mEglConfig, surfaceHolder, null); ... error checking ... mEgl.eglMakeCurrent(mEglDisplay, mEglSurface, mEglSurface, mEglContext); When the window-surface is created, it ends up with the same ptr address as the recently freed tmpSurface pbuffer surface. Which after many levels of indirection, results in st_framebuffer_validate() ending up with the same/old framebuffer object, and in the end never calling the DRIimageLoaderExtension::getBuffers(). Then in droid_swap_buffers(), the dri2_surf is still the old pbuffer surface (with dri2_surf->buffer being NULL, obviously, so when wallpaper app calls eglSwapBuffers() nothing gets enqueued to the compositor). Resulting in a black/blank background layer. Note that at the EGL layer, when the context is unbound, EGL drops it's references to the draw and read buffer as well.

* mesa: Add linear ETC2/EAC to the compressed format list with ES3 compat.Kenneth Graunke2016-11-041-6/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | GL_ARB_ES3_compatibility brings ETC2/EAC formats to desktop GL. The meaning of the GL compressed format list is pretty vague - it's supposed to return formats for "general-purpose usage". (GL 4.2 deprecates the list because of this.) Basically everyone interprets this as "linear RGB/RGBA". ETC2/EAC meets that criteria, so while we shouldn't be required to add it to the list, there's also little harm in doing so, at least on platforms with native support. I doubt anyone is using this list for much anyway, so even on platforms without native support, it's probably not a big deal. Makes the following GL45-CTS.gtf43 tests pass: * GL3Tests.eac_compression_r11.gl_compressed_r11_eac * GL3Tests.eac_compression_rg11.gl_compressed_rg11_eac * GL3Tests.eac_compression_signed_r11.gl_compressed_signed_r11_eac * GL3Tests.eac_compression_signed_rg11.gl_compressed_signed_rg11_eac * GL3Tests.etc2_compression_rgb8.gl_compressed_rgb8_etc2 * GL3Tests.etc2_compression_rgb8_pt_alpha1.gl_compressed_rgb8_pt_alpha1_etc2 * GL3Tests.etc2_compression_rgba8.gl_compressed_rgba8_etc2 Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Eduardo Lima Mitev <[email protected]>
* mesa/glsl: delete previously linked shaders earlier when linkingTimothy Arceri2016-11-032-14/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This moves the delete linked shaders call to _mesa_clear_shader_program_data() which makes sure we delete them before returning due to any validation problems. It also reduces some code duplication. From the OpenGL 4.5 Core spec: "If LinkProgram failed, any information about a previous link of that program object is lost. Thus, a failed link does not restore the old state of program. ... If one of these commands is called with a program for which LinkProgram failed, no error is generated unless otherwise noted. Implementations may return information on variables and interface blocks that would have been active had the program been linked successfully. In cases where the link failed because the program required too many resources, these commands may help applications determine why limits were exceeded." Therefore it's expected that we shouldn't be able to query the program that failed to link and retrieve information about a previously successful link. Before this change the linker was doing validation before freeing the previously linked shaders and therefore could exit on failure before they were freed. This change also fixes an issue in compat profile where a program with no shaders attached is expect to fall back to fixed function but was instead trying to relink IR from a previous link.
