This file describes the configuration and behavior of KGDB for the SH
kernel. Based on a description from Henry Bell <henry.bell@st.com>, it
has been modified to account for quirks in the current implementation.
Version
=======
This version of KGDB was written for 2.4.xx kernels for the SH architecture.
Further documentation is available from the linux-sh project website.
Debugging Setup: Host
======================
The two machines will be connected together via a serial line - this
should be a null modem cable i.e. with a twist.
On your DEVELOPMENT machine, go to your kernel source directory and
build the kernel, enabling KGDB support in the "kernel hacking" section.
This includes the KGDB code, and also makes the kernel be compiled with
the "-g" option set -- necessary for debugging.
To install this new kernel, use the following installation procedure.
Decide on which tty port you want the machines to communicate, then
cable them up back-to-back using the null modem. On the DEVELOPMENT
machine, you may wish to create an initialization file called .gdbinit
(in the kernel source directory or in your home directory) to execute
commonly-used commands at startup.
A minimal .gdbinit might look like this:
file vmlinux
set remotebaud 115200
target remote /dev/ttyS0
Change the "target" definition so that it specifies the tty port that
you intend to use. Change the "remotebaud" definition to match the
data rate that you are going to use for the com line (115200 is the
default).
Debugging Setup: Target
========================
By default, the KGDB stub will communicate with the host GDB using
ttySC1 at 115200 baud, 8 databits, no parity; these defaults can be
changed in the kernel configuration. As the kernel starts up, KGDB will
initialize so that breakpoints, kernel segfaults, and so forth will
generally enter the debugger.
This behavior can be modified by including the "kgdb" option in the
kernel command line; this option has the general form:
kgdb=<ttyspec>,<action>
The <ttyspec> indicates the port to use, and can optionally specify
baud, parity and databits -- e.g. "ttySC0,9600N8" or "ttySC1,19200".
The <action> can be "halt" or "disabled". The "halt" action enters the
debugger via a breakpoint as soon as kgdb is initialized; the "disabled"
action causes kgdb to ignore kernel segfaults and such until explicitly
entered by a breakpoint in the code or by external action (sysrq or NMI).
(Both <ttyspec> and <action> can appear alone, w/o the separating comma.)
For example, if you wish to debug early in kernel startup code, you
might specify the halt option:
kgdb=halt
Boot the TARGET machine, which will appear to hang.
On your DEVELOPMENT machine, cd to the source directory and run the gdb
program. (This is likely to be a cross GDB which runs on your host but
is built for an SH target.) If everything is working correctly you
should see gdb print out a few lines indicating that a breakpoint has
been taken. It will actually show a line of code in the target kernel
inside the gdbstub activation code.
NOTE: BE SURE TO TERMINATE OR SUSPEND any other host application which
may be using the same serial port (for example, a terminal emulator you
have been using to connect to the target boot code.) Otherwise, data
from the target may not all get to GDB!
You can now use whatever gdb commands you like to set breakpoints.
Enter "continue" to start your target machine executing again. At this
point the target system will run at full speed until it encounters
your breakpoint or gets a segment violation in the kernel, or whatever.
Serial Ports: KGDB, Console
============================
This version of KGDB may not gracefully handle conflict with other
drivers in the kernel using the same port. If KGDB is configured on the
same port (and with the same parameters) as the kernel console, or if
CONFIG_SH_KGDB_CONSOLE is configured, things should be fine (though in
some cases console messages may appear twice through GDB). But if the
KGDB port is not the kernel console and used by another serial driver
which assumes different serial parameters (e.g. baud rate) KGDB may not
recover.
Also, when KGDB is entered via sysrq-g (requires CONFIG_KGDB_SYSRQ) and
the kgdb port uses the same port as the console, detaching GDB will not
restore the console to working order without the port being re-opened.
Another serious consequence of this is that GDB currently CANNOT break
into KGDB externally (e.g. via ^C or <BREAK>); unless a breakpoint or
error is encountered, the only way to enter KGDB after the initial halt
(see above) is via NMI (CONFIG_KGDB_NMI) or sysrq-g (CONFIG_KGDB_SYSRQ).
Code is included for the basic Hitachi Solution Engine boards to allow
the use of ttyS0 for KGDB if desired; this is less robust, but may be
useful in some cases. (This cannot be selected using the config file,
but only through the kernel command line, e.g. "kgdb=ttyS0", though the
configured defaults for baud rate etc. still apply if not overridden.)
If gdbstub Does Not Work
========================
If it doesn't work, you will have to troubleshoot it. Do the easy
things first like double checking your cabling and data rates. You
might try some non-kernel based programs to see if the back-to-back
connection works properly. Just something simple like cat /etc/hosts
/dev/ttyS0 on one machine and cat /dev/ttyS0 on the other will tell you
if you can send data from one machine to the other. There is no point
in tearing out your hair in the kernel if the line doesn't work.
If you need to debug the GDB/KGDB communication itself, the gdb commands
"set debug remote 1" and "set debug serial 1" may be useful, but be
warned: they produce a lot of output.
Threads
=======
Each process in a target machine is seen as a gdb thread. gdb thread related
commands (info threads, thread n) can be used. CONFIG_KGDB_THREAD must
be defined for this to work.
In this version, kgdb reports PID_MAX (32768) as the process ID for the
idle process (pid 0), since GDB does not accept 0 as an ID.
Detaching (exiting KGDB)
=========================
There are two ways to resume full-speed target execution: "continue" and
"detach". With "continue", GDB inserts any specified breakpoints in the
target code and resumes execution; the target is still in "gdb mode".
If a breakpoint or other debug event (e.g. NMI) happens, the target
halts and communicates with GDB again, which is waiting for it.
With "detach", GDB does *not* insert any breakpoints; target execution
is resumed and GDB stops communicating (does not wait for the target).
In this case, the target is no longer in "gdb mode" -- for example,
console messages no longer get sent separately to the KGDB port, or
encapsulated for GDB. If a debug event (e.g. NMI) occurs, the target
will re-enter "gdb mode" and will display this fact on the console; you
must give a new "target remote" command to gdb.
NOTE: TO AVOID LOSSING CONSOLE MESSAGES IN CASE THE KERNEL CONSOLE AND
KGDB USING THE SAME PORT, THE TARGET WAITS FOR ANY INPUT CHARACTER ON
THE KGDB PORT AFTER A DETACH COMMAND. For example, after the detach you
could start a terminal emulator on the same host port and enter a <cr>;
however, this program must then be terminated or suspended in order to
use GBD again if KGDB is re-entered.

This adds the cpufreq driver for SuperH. At present, only
the SH-4 is supported.
This adds the cpufreq driver for SuperH. Any CPU that supports
clock rate rounding through the clock framework can use this
driver. While it will make the kernel slightly larger, this is
harmless for CPUs that don't support rate rounding. The driver
will also generate a notice in the boot log before disabling
itself if the CPU in question is not capable of rate rounding.
For details, take a look at <file:Documentation/cpu-freq>.

/* Dreamcast System ASIC Hardware Events -
The Dreamcast's System ASIC (a.k.a. Holly) is responsible for receiving
hardware events from system peripherals and triggering an SH7750 IRQ.
Hardware events can trigger IRQs 13, 11, or 9 depending on which bits are
set in the Event Mask Registers (EMRs). When a hardware event is
triggered, it's corresponding bit in the Event Status Registers (ESRs)
is set, and that bit should be rewritten to the ESR to acknowledge that
event.
There are three 32-bit ESRs located at 0xa05f8900 - 0xa05f6908. Event
types can be found in include/asm-sh/dreamcast/sysasic.h. There are three
groups of EMRs that parallel the ESRs. Each EMR group corresponds to an
IRQ, so 0xa05f6910 - 0xa05f6918 triggers IRQ 13, 0xa05f6920 - 0xa05f6928
triggers IRQ 11, and 0xa05f6930 - 0xa05f6938 triggers IRQ 9.
In the kernel, these events are mapped to virtual IRQs so that drivers can
respond to them as they would a normal interrupt. In order to keep this
mapping simple, the events are mapped as:
6900/6910 - Events 0-31, IRQ 13
6904/6924 - Events 32-63, IRQ 11
6908/6938 - Events 64-95, IRQ 9

/*
* This implements a small wrapper set to make code using the old ISA DMA API
* work with the SH DMA API. Since most of the work in the new API happens
* at ops->xfer() time, we simply use the various set_dma_xxx() routines to
* fill in per-channel info, and then hand hand this off to ops->xfer() at
* enable_dma() time.
*
* For channels that are doing on-demand data transfer via cascading, the
* channel itself will still need to be configured through the new API. As
* such, this code is meant for only the simplest of tasks (and shouldn't be
* used in any new drivers at all).
*
* NOTE: ops->xfer() is the preferred way of doing things. However, there
* are some users of the ISA DMA API that exist in common code that we
* don't necessarily want to go out of our way to break, so we still
* allow for some compatibility at that level. Any new code is strongly
* advised to run far away from the ISA DMA API and use the SH DMA API
* directly.
