* Mutexes in pixelrefs were done very sloppily initially. The code (a) assumes allGravatar reed@google.com2012-05-17
| | | | | | | | | | | | | | | | | | | | pixelref subclasses want a mutex to guard their lock/unlock virtuals, and (b) most subclasses use the same mutex for *all* of their instances, even when there is no explicit need to guard modifying one instances with another. When we try drawing bitmaps from multiple threads, we are seeing a lot of slow- down from these mutexes. This CL has two changes to try to speed things up. 1. Add setPreLocked(), for pixelrefs who never need the onLockPixels virtual to be called. This speeds up those subclasses in multithreaded environs as it avoids the mutex lock all together (e.g. SkMallocPixelRef). 2. Add setMutex() to allow a subclass to change the mutex choice. ashmem wants this, since its unflattening constructor cannot pass down the null, it needs to cleanup afterwards.

* Adding the notion of a volatile bitmap to SkBitmap. Gravatar junov@google.com2011-06-30
| | | | | | | | | | | | | | | | | Volatility is a hint that indicates that the contents of a bitmap are ephemeral. SkGpuDevice will not preserve volatile bitmaps in its texture cache, and will use textures from a pool of keyless (recyclable) textures to avoid the performance hit of texture allocation and release. A subsequent change is required in webkit in order to take advantage of this optimization. putImageData, and other methods that create temporary bitmaps will have to mark their bitmaps as volatile. before rendering them through skia. git-svn-id: http://skia.googlecode.com/svn/trunk@1769 2bbb7eff-a529-9590-31e7-b0007b416f81

* remove SkRefCnt safeRef() and safeUnref(), and replace the call-sites withGravatar reed@google.com2011-02-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SkSafeRef() and SkSafeUnref(). This is basically a bug waiting to happen. An optimizing compiler can remove checks for null on "this" if it chooses. However, SkRefCnt::safeRef() relies on precisely this check... void SkRefCnt::safeRef() { if (this) { this->ref(); } } Since a compiler might skip the if-clause, it breaks the intention of this method, hence its removal. static inline void SkSafeRef(SkRefCnt* obj) { if (obj) { obj->ref(); } } This form is not ignored by an optimizing compile, so we use it instead. git-svn-id: http://skia.googlecode.com/svn/trunk@762 2bbb7eff-a529-9590-31e7-b0007b416f81

* Add safe size/copy functions to Skia.Gravatar wjmaclean@chromium.org2010-11-16
| | | | | | | | | | | | | | | | | | | | | | This patch adds four methods to SkBitmap. There are two functions to return "safe size", defined as the number of pixels from the value returned by getPixels() to the end of the allocated buffer. There is one version of fillPixels() to copy the bitmap instance into an external buffer (with specified size, and using specified stride), and another fillPixels() to copy from an external buffer to the instance bitmap. In the latter case the specified height, width and pixel format must match that used by the bitmap instance, although the specified stride may be any value at least as large as the minimum stride for the specified geometry. It is assumed that the external buffer is of size at least (height - 1)*stride + width * bytesPerPixel. Both fillPixels() functions return false if the copy is not possible with the specified parameters.
