When enabled in the PBA, any OCI write -/// transactions of any size are ACK'ed by the PBA and the data is ignored. -/// This creates an OCI transaction record that can be captured by the NHTM -/// for later analysis. -/// -/// SSX provides a generic SSX_TRACE() macro that accepts a single -/// parameter. On PgP, valid parameters are integers in the range -/// 0x0,...,0xffff. The PgP SSX kernel reserves trace addresses -/// 0xe000,...,0xffff for kernel event traces. Applications are free to use -/// the other trace addresses in the range 0x0000,...,0xdfff as they see fit. -/// -/// Application tracing is globally disabled by default, and is enabled by -/// defining the switch SSX_TRACE_ENABLE=1. Kernel event tracing is also -/// globally disabled by default, and is enabled by defining the switch -/// SSX_KERNEL_TRACE_ENABLE=1. Kernel event tracing adds overhead to every -/// interrupt handler and kernel API so should probably remain disabled unless -/// required. -/// -/// The Simics PBA model supports trace reporting, either to stdout or to a -/// file. To enable trace reporting set pba->trace_report = 1. To capture -/// traces to a file other than stdout, set pba->trace_file = \<filename\>. The -/// Simics model understands SSX kernel trace events and produces a readable -/// commentary of kernel traces events - user events will be reported simply -/// as the integer tag. - -#include "pgp_common.h" - -/// Output an OCI Trace Marker -/// -/// See the comments for the file pgp_trace.h - -#if SSX_TRACE_ENABLE -#define SSX_TRACE(event) out8(PBA_OCI_MARKER_BASE + (event), 0) -#endif - -#if SSX_KERNEL_TRACE_ENABLE - -// Note: The *BASE constants are defined in pgp_common.h - -#define SSX_KERNEL_TRACE(event) out8(PBA_OCI_MARKER_BASE + (event), 0) - -#define SSX_TRACE_THREAD_SLEEP(priority) \ - SSX_KERNEL_TRACE(SSX_TRACE_THREAD_SLEEP_BASE + priority) - -#define SSX_TRACE_THREAD_WAKEUP(priority) \ - SSX_KERNEL_TRACE(SSX_TRACE_THREAD_WAKEUP_BASE + priority) - -#define SSX_TRACE_THREAD_SEMAPHORE_PEND(priority) \ - SSX_KERNEL_TRACE(SSX_TRACE_THREAD_SEMAPHORE_PEND_BASE + priority) - -#define SSX_TRACE_THREAD_SEMAPHORE_POST(priority) \ - SSX_KERNEL_TRACE(SSX_TRACE_THREAD_SEMAPHORE_POST_BASE + priority) - -#define SSX_TRACE_THREAD_SEMAPHORE_TIMEOUT(priority) \ - SSX_KERNEL_TRACE(SSX_TRACE_THREAD_SEMAPHORE_TIMEOUT_BASE + priority) - -#define SSX_TRACE_THREAD_SUSPENDED(priority) \ - SSX_KERNEL_TRACE(SSX_TRACE_THREAD_SUSPENDED_BASE + priority) - -#define SSX_TRACE_THREAD_DELETED(priority) \ - SSX_KERNEL_TRACE(SSX_TRACE_THREAD_DELETED_BASE + priority) - -#define SSX_TRACE_THREAD_COMPLETED(priority) \ - SSX_KERNEL_TRACE(SSX_TRACE_THREAD_COMPLETED_BASE + priority) - -#define SSX_TRACE_THREAD_MAPPED_RUNNABLE(priority) \ - SSX_KERNEL_TRACE(SSX_TRACE_THREAD_MAPPED_RUNNABLE_BASE + priority) - -#define SSX_TRACE_THREAD_MAPPED_SEMAPHORE_PEND(priority) \ - SSX_KERNEL_TRACE(SSX_TRACE_THREAD_MAPPED_SEMAPHORE_PEND_BASE + priority) - -#define SSX_TRACE_THREAD_MAPPED_SLEEPING(priority) \ - SSX_KERNEL_TRACE(SSX_TRACE_THREAD_MAPPED_SLEEPING_BASE + priority) - -#endif /* SSX_KERNEL_TRACE_ENABLE */ - - -#ifdef __ASSEMBLER__ - -// NB: CPP macros are not expanded as arguments to .if in GAS macro -// definitions.
