Build Speakup Modules

[keith@xxxxxxxxxx (Keith Wessel)]

Trevor,

I presume your modification to serialio.c will get hardware synths working,
but only for on-board serial ports and not add-on PCI serial ports. Is that
a correct assumption? From what I've both heard and found for myself in the
Speakup source, add-on serial port support takes more than what you've done,
but I could be wrong.

Keith

Subject: Build Speakup Modules

Here is how I built speakup as modules for my distribution kernel (Debian
Jessie 3.10-2-amd64) without having to configure and compile the kernel.

The below requires that you have the kernel headers for your distribution's
kernel installed. You should have some files and directories under
/lib/modules/<kernel_ver>/build. On my system, `ls
/lib/modules/3.10-2-amd64/build' shows the following:

 	arch  include  Makefile  Module.symvers  scripts


First, download the speakup source code if you don't already have it.

$ git clone http://linux-speakup.org/speakup.git

Change to the actual source directory:

$ cd speakup/drivers/staging/speakup

Rename Makefile to Kbuild:

$ mv Makefile Kbuild

Save the attached Makefile to speakup/drivers/staging/speakup/Makefile and
follow the instructions in speakup/INSTALLATION for building speakup as
modules.

The modules will be installed in /lib/modules/<kernel_ver>/extra. If your
distribution kernel includes speakup, you will need to move them to
/lib/modules/<kernel_ver>/kernel/drivers/staging/speakup to avoid any
confusion with the version installed by your distribution.

# mv /lib/modules/<kernel_ver>/extra/*.ko \
      /lib/modules/<kernel_ver>/kernel/drivers/staging/speakup

Run depmod to update module dependencies:

# depmod <kernel_ver>

Lastly, update the init image with the new speakup modules and boot your
kernel. In Debian you can run:

# update-initramfs -u

If you are using a hardware synth, you may need to modify the speakup source
in order to get speech. If this is the case for you, edit
speakup/drivers/staging/speakup/serialio.c and remove the below around line
37. Then repeat these instructions.

         if (synth_request_region(ser->port, 8)) {
                 /* try to take it back. */
                 printk(KERN_INFO "Ports not available, trying to steal
them\n");
                 __release_region(&ioport_resource, ser->port, 8);
                 err = synth_request_region(ser->port, 8);
                 if (err) {
                         pr_warn("Unable to allocate port at %x, errno %i",
                                 ser->port, err);
                         return NULL;
                 }
         }
