Subject: [PATCH 22/39] NLKD - core
Date: Wed, 09 Nov 2005 15:18:55 +0100 [thread overview]
Message-ID: <4372135F.76F0.0078.0@novell.com> (raw)
In-Reply-To: 43721184.76F0.0078.0@novell.com
[-- Attachment #1: Type: text/plain, Size: 420 bytes --]
The core NLKD additions.
With other debugging code living scattered across the (official or
external) tree(s), this tries to atb once establish a common place
for debugging code in a new debug/ directory.
Note that this depends on the i386 cmpxchg adjustments patch, which
isn't in 2.6.14, but has supposedly been merged already into 2.6.15.

+ * Number Of Handlers: One
+ * Other Notes: This is the OS default handler for the interruption.
+ * This handler slot is reserved for OS kernel use only.
+ * An attempt to register for this handler slot will fail

+ * FTA_INTERRUPTION_HANDLER_GENERAL_PURPOSE
+ * Frame Modification: Allowed
+ * Number Of Handlers: Multiple
+ * Other Notes: General purpose handlers are maintained on a
+ * linked list and are called on a first linked, first

+ * the interruption has been handled by its return
+ * status other general purpose handlers will not be
+ * invoked.
+ *
+ * FTA_INTERRUPTION_HANDLER_HEALTH_MONITOR
+ * Frame Modification: Not Allowed
+ * Number Of Handlers: One
+ * Other Notes: The health driver may perform such actions as
+ * monitoring the health of the system or logging
+ * the cause of critical errors to NVRAM prior to a
+ * system crash. A health handler may view the contents
+ * of the frame but should not modify the frame contents.
+ * If modification of the frame is required a separate
+ * general purpose handler should be registered.
+ * An attempt to register for this handler slot will fail
+ * until the previous handler has been cleared.
+ *
+ * FTA_INTERRUPTION_HANDLER_APPLICATION_DEBUGGER
+ * Frame Modification: Allowed
+ * Number Of Handlers: Multiple
+ * Other Notes: An application level debugger registration will
+ * take precedence over kernel level debuggers.
+ *
+ * FTA_INTERRUPTION_HANDLER_CORE_DEBUG_ENGINE
+ * Frame Modification: Allowed
+ * Number Of Handlers: One
+ * Other Notes: The intention here is to allow the CDE an early peek at the
+ * the frame to recover from internally generated interruptions.
+ *
+ * FTA_INTERRUPTION_PATCH_REPLACEMENT
+ * Frame Modification: Allowed
+ * Number Of Handlers: One
+ * Other Notes: A patch replacement handler provides a mechanism whereby
+ * the infrastructure for a given interruption may be
+ * completely replaced. The writer of this handler should
+ * be intimately familiar with the requirements of the
+ * interruption event. This slot is provided as a means
+ * field replacement of the interruption handling infrastructure
+ * may be replaced. Please see ftaGetInterruptionHandlers()

+/*
+ * The purpose of this file is to provide a common format and encoding
+ * scheme for API status codes.
+ * The status classification and naming conventions used in this file are
+ * as follows.
+ *
+ * LSTATUS is defined as a native unsigned return code. There are four
+ * parts to the status. The low bits contain the status code. The next
+ * portion contains the sybsystem identifier, followed by an optional
+ * subsystem specific unique identifier. The top bits
+ * The unique ID may be used in a number of ways and is subsystem
+ * specific. It is optional and should be zero if not used.
+ *
+ * The LSTATUS return code may be viewed as a union defined as follows:
+ *
+ * typedef union {
+ * struct {
+ * nuint_t status:N1;
+ * nuint_t subsystem:N2;
+ * nuint_t uniqueId:N3;
+ * nuint_t category:N4;
+ * } fields;
+ * LSTATUS status;
+ * } lStatus_t;
+ *
+ * Each major subsystem within may allocate a range of status codes by
+ * adding a #define to the classification section below.
+ * The convention allows for 255/65535 subsystems in the system with each
+ * subsystem being allowed to define up to as many as 4095/65535 unique
+ * status codes or errors. This should be adequate.
+ *
+ * The first subsystem known as LSTATUS_ is a general purpose
+ * classification to be used for smaller subsystems, components or
+ * stand alone APIs which do not clearly fit into a larger grouping.
+ * Status code additions to the general area should be carefully chosen
+ * and somewhat generic in flavor as another developer of a different
+ * component may also use that defined status/error code.
+ *
+ * In general you are encouraged to create unique classifications
+ * for large and middle sized subcomponents of the kernel.
+ *
+ * Status code return types are 32/64 bits in size.
+ *
+ * Nano kernel subsystems are numbered using bits 31:16.
+ *
+ * Status codes within each subsystem are defined using bits 15:0.
+ *
+ * The status codes 0-255 in each {category,subsystem} must be identical
+ * to those in the generic subsystem. The first unique status code in any
+ * given subsystem should not be less than 256. This convention will
+ * allow us to become familiar with return codes < 256 regardless of what
+ * subsystem the status code came from.
+ *
+ * We do not expect to have more that 256 generic status codes.
+ *
+ * Specific status definitions within a general classification may be
+ * defined in another header file more specific to the subcomponent.
+ * However, general subsystem classifications must be defined in this
+ * file and listed in numeric order. Status code definitions in the generic
+ * classification, LSTATUS_, must also be listed in this file.
+ *
+ * APIs returning status codes defined by this file must be declared to
+ * return LSTATUS. LSTATUS is defined as a nuint_t.
+ *
+ *
+ * Naming:
+ * For the purposes of providing a common look and feel, and to avoid
+ * naming conflicts the defined names of each status code shall follow the
+ * rules below.
+ *
+ * 1) The status code will be described in all capital letters with the under
+ * score chararacter separating descriptive words.
+ *
+ * 2) The status code will be prefixed with the classification name.
+ * Example: Status codes in the SCHED subclassification will begin
+ * with LSTATUS_SCHED.
+ *
+ * 3) The descriptive portion of the status code definition will follow the
+ * the general classification.
+ * Example: LSTATUS_SCHED_PARAMETER_INVALID.
