GL+trace日志增强 — 分析每一帧 vulkan内存申请
创建所有texture的方法中 输出尺寸
正常情况在prepareTree或者renderFrameImpl阶段去创建texture时，都可以正常找到对应的view
如果创建texture阶段在flush layers，则需要添加更详细的tag，如下：

//external/skia/src/gpu/ganesh/GrResourceAllocator.cpp
bool GrResourceAllocator::assign() {
if (fFailedInstantiation) {
return false;
}
SkASSERT(fPlanned && !fAssigned);
SkDEBUGCODE(fAssigned = true;)
auto resourceProvider = fDContext->priv().resourceProvider();
//从fFinishedIntvls中按顺序取出Interval，一个optask会对应多个intvl，需要在intvl收集的时候就找到其对应的optask
while (Interval* cur = fFinishedIntvls.popHead()) {
if (fFailedInstantiation) {
break;
}
if (cur->proxy()->isInstantiated()) {
continue;
}
if (cur->proxy()->isLazy()) {
fFailedInstantiation = !cur->proxy()->priv().doLazyInstantiation(resourceProvider);
continue;
}
Register* r = cur->getRegister();
SkASSERT(r);
fFailedInstantiation = !r->instantiateSurface(cur->proxy(), resourceProvider);
}
return !fFailedInstantiation;
}- 需要在Interval初始化时就创建一个uniqueID，当Interval 去createTexture时，就输出构造Interval时创建的ID；
- 同时在Interval创建时，打印出task id，这样就可以通过 Interval id → task id → view的步骤找到对应的veiw
GL mtrack 拆解实战
通过cat mem_profile获取详细buffer通道，主要受Channel: GFX Device Memory CPU Uncached 、Vulkan Bound Buffer Memory、Vulkan Bound Image Memory三部分影响，具体buffer大小如下：
Channel: GFX Device Memory CPU Uncached (Total memory: 21606400)
Bin id Count / Memory
13: 2 / 8192
14: 8 / 65536
17: 3 / 270336
21: 2 / 2105344
22: 1 / 2101248
23: 4 / 17055744
Channel: Vulkan Bound Buffer Memory (Total memory: 385284)
Bin id Count / Memory
8: 2 / 372
9: 33 / 12560
10: 18 / 11520
11: 12 / 18816
15: 1 / 30720
16: 5 / 180224
17: 2 / 131072
Channel: Vulkan Bound Image Memory (Total memory: 17353152)
Bin id Count / Memory
14: 16 / 187456
15: 20 / 420992
16: 11 / 377472
18: 3 / 651264
19: 2 / 774656
20: 16 / 10484864
23: 1 / 4456448
操作后：
Channel: GFX Device Memory CPU Uncached (Total memory: 25804800)
Bin id Count / Memory
13: 2 / 8192
14: 8 / 65536
17: 3 / 270336
21: 2 / 2105344
22: 1 / 2101248
23: 5 / 21254144频繁操作某个场景后，GFX Device Memory CPU Uncached多了一个4198400大小的buffer不释放。

结合上文提到的GL+trace方案：
创建该texture的原因是 DynamicIslandContentFakeView要做alpha操作，需要创建离屏的buffer，特别注意，对于view的alpha操作需要在view可见时进行，不然可能出现预期之外的内存泄漏问题O8-OS2.2 GPU memory泄漏问题分析，https://gerrit.pt.mioffice.cn/c/platform/packages/apps/MiuiSystemUI/+/5667746
- 对于效果不明显或者没有view重叠的alpha操作，可以改成非离屏渲染，优化性能；
其他Allocate mem的地方还有很多，需要添加对应的tag去定位问题，添加方式和GL+trace日志增强方案类似
- 不通过GrResourceAllocator::assign()调用的堆栈：

任航https://gerrit.pt.mioffice.cn/q/topic:%22gfxinfo+dump%22
gfxinfo可以用于分析和优化应用程序的图形渲染性能
我们可以粗略看到GPU mem信息以及buffer尺寸和内存大小
对于具体分析问题这些信息可能不够，采用如下的日志增强方案可以看到详细的GrVkImage、GrVkTextureRenderTarget、Buffer Object的尺寸以及大小信息。
- gfxinfo的dump信息在CacheManager::dumpMemoryUsage方法输出
frameworks/base/libs/hwui/renderthread/CacheManager.cpp
- SkiaMemoryTracer是SkTraceMemoryDump子类
libs/hwui/pipeline/skia/SkiaMemoryTracer.h
在GrGpuResource::dumpMemoryStatisticsPriv中调用SkiaMemoryTracer定义的dumpLogcat方法把buffer的type，size输出到dump信息中；
- 这些type和size都是GrGpuResource子类调用自身dump信息得到。
external/skia/src/gpu/ganesh/GrGpuResource.cpp
void GrGpuResource::dumpMemoryStatistics(SkTraceMemoryDump* traceMemoryDump) const {
if (this->fRefsWrappedObjects && !traceMemoryDump->shouldDumpWrappedObjects()) {
return;
}
this->dumpMemoryStatisticsPriv(traceMemoryDump, this->getResourceName(),
this->getResourceType(), this->gpuMemorySize());
}
void GrGpuResource::dumpMemoryStatisticsPriv(SkTraceMemoryDump* traceMemoryDump,
const SkString& resourceName,
const char* type, size_t size) const {
const char* tag = "Scratch";
if (fUniqueKey.isValid()) {
tag = (fUniqueKey.tag() != nullptr) ? fUniqueKey.tag() : "Other";
}
traceMemoryDump->dumpNumericValue(resourceName.c_str(), "size", "bytes", size);
traceMemoryDump->dumpStringValue(resourceName.c_str(), "type", type);
traceMemoryDump->dumpStringValue(resourceName.c_str(), "label", this->getLabel().c_str());
traceMemoryDump->dumpStringValue(resourceName.c_str(), "category", tag);
if (this->isPurgeable()) {
traceMemoryDump->dumpNumericValue(resourceName.c_str(), "purgeable_size", "bytes", size);
}
if (traceMemoryDump->shouldDumpWrappedObjects()) {
traceMemoryDump->dumpWrappedState(resourceName.c_str(), fRefsWrappedObjects);
}
this->setMemoryBacking(traceMemoryDump, resourceName);
}- 常见子类包括GrVkTextureRenderTarget和GrVkImage等，可以根据需求重写getResourceType方法
GrVkImage：用于存储多维数据，如纹理、帧缓冲等；GrVkTextureRenderTarget：提供了一个可以同时用作纹理和渲染目标的资源；Buffer Object：用于存储线性数据，如顶点数据、索引数据、uniform 数据等；
这样我们可以在gfxinfo中看到通过vkAllocateMemory申请的详细内存以及对应的尺寸信息，协助分析。
