[PATCH 0/1] kbd: Limit the kbdrate application to x86, mips and sparc

[jackie.huang]

From: Jackie Huang <jackie.huang@windriver.com>

Tested with:
1)
MACHINE = "qemux86-64"
IMAGE_INSTALL_append = " kbd"

2)
MACHINE = "qemuppc"
IMAGE_INSTALL_append = " kbd"

3)
MACHINE = "qemuarm"
IMAGE_INSTALL_append = " kbd"

4)
MACHINE = "qemumips"
IMAGE_INSTALL_append = " kbd"

build:
$ bitbake core-image-minimal
$ runqemu qemux86-64 core-image-minimal ext3 nographic

run on qemu targets:
# kbdrate

[PATCH 1/1] Limit the kbdrate application to x86, mips and sparc.

[jackie.huang]

From: Jackie Huang <jackie.huang@windriver.com>

The code relies on hardware specific memory locations to access
and modify the keyboard repeat rate.  It also requires read/write
access to /dev/port which doesn't exist on every architecture's
root fs.  The defect was raised for Qemu PowerPC but it also fails on
ARM.  The keyboard emulation in qemuppc is for an ADB (Apple Desktop Bus)
device and not compatible with an Intel driver.  There's also no
indication in the documentation that the code should work on
anything other than Intel architecture but it also works on MIPS.

+Upstream-Status: Pending
+
+The application will exit with an error if it runs on any other architecture.
+
+The code relies on hardware specific memory locations to access
+and modify the keyboard repeat rate.  It also requires read/write
+access to /dev/port which doesn't exist on every architecture's
+root fs.  The CQ was raised for Qemu PowerPC but it also fails on

+MIPS64 is not supported at this time so it was not tested.

Would it be better to detect the target platform in the build system and
skip building the kbdrate program for architectures it won't work on rather
than building and installing a known broken program?

Accidental repeat?

Yeah, it should be better, I will check if we can do that.

Indeed, thanks for pointing this out.

We're after to take out a single binary, not the whole recipe?

Yes, not the whole recipe, kbdrate is just one of the biaries provided 
by the kbd package, so I think it's not appropriate to use 
COMPATIBLE_MACHINE here.
