Observe que a saída do depurador pode conter uma mistura de objetos ACX públicos, como ACXMANAGER, ACXCIRCUITFACTORY e ACXCIRCUIT e estruturas internas definidas como opacas. Não é garantido que os tipos internos permaneçam os mesmos ou estejam disponíveis em diferentes versões do ACX, eles não devem ser chamados nem usados diretamente.

Como os objetos ACX são objetos WDF, você pode usar o comando !wdfkd.wdfhandle para exibir informações adicionais sobre o objeto ACXMANAGER.

Exemplo de passo a passo do driver ACX

Esta seção fornece um passo a passo da depuração de um driver ACX.

Caminho dos símbolos

Use os comandos .symfix e . sympath (Set Symbol Path) para alterar o caminho do símbolo. Se você estiver usando o código local com o driver, adicione o caminho para esse código também. Use o comando .reload (Recarregar Módulo) para recarregar símbolos do caminho atual.

.symfix
.sympath+ C:\Windows-driver-samples-develop\audio\Acx\Samples\AudioCodec\Driver
.reload /f

Contexto do depurador para drivers

Se você estiver depurando um driver ACX ativo, defina um ponto de interrupção. Isso coloca o depurador no contexto dos objetos ACX, para poder coletar e exibir informações.

Esses pontos de interrupção de exemplo são projetados para serem acionados quando o driver AudioCodec de exemplo for iniciado.

bm AudioCodec!DriverEntry
bm AudioCodec!AcxDriverInitialize

Esses pontos de interrupção de exemplo são projetados para serem acionados quando ocorrem ações específicas, como a criação de pinos ou circuitos.

bm AudioCodec!AcxPinCreate
bm AudioCodec!AcxCircuitCreate
bm AudioCodec!Codec_EvtBusDeviceAdd

Depois que o driver for carregado e o ponto de interrupção apropriado tiver sido acionado e o contexto de execução válido estiver disponível, use os comandos !acxkd para exibir informações sobre qualquer objeto ACX. Use o comando !acxobject para obter informações gerais e um comando específico, como !acxcircuit ou !acxpin para obter informações mais granulares.

Carregue a dll acxkd

Use o comando .load (Load Extension DLL) para carregar a extensão acxkd.dll.

.load acxkd.dll

Exibir informações sobre o driver ACX

Para coletar informações sobre o driver de destino, use o comando lm (List Loaded Modules) para ver todos os drivers carregados. Em seguida, use as opções Dvm para exibir informações sobre o driver ACX de interesse, conforme mostrado aqui.
