Hi,
Is there any feasible way to dereference a pointer inside
__mod_*_device_table which points to a string?
e.g.:
include/linux/mod_devicetable.h:
struct pcmcia_device_id {
...
const char * prod_id;
...
}
drivers/some/driver.c:
static struct pcmcia_device_id
Andrew, Linus, all,
[note: for detailed code please take a look at 2.6.11-mm2]
Most pcmcia devices are matched to drivers using "product ID strings"
embedded in the devices' Card Information Structures, as "manufactor ID /
card ID" matches are much less reliable. Unfortunately, these strings
compiling -mm2 on my x86 box results in:
SYSMAP .tmp_System.map
Inconsistent kallsyms data
Try setting CONFIG_KALLSYMS_EXTRA_PASS
make: *** [vmlinux] Fehler 1

Fixed by upgrading the userspace script used by him to include
"cardctl eject && sleep 1"
before killing cardmgr, as killing cardmgr no longer auto-detaches PCMCIA
dpm_runtime_suspend and _resume() would be quite useful for some PCMCIA
tasks. However, they are only exported in drivers/base/power/power.h. Any
objection to moving it to include/linux/pm.h ? Any plans to break the
functionality these functions provide?

Hi!
The PowerOP infrastructure you suggest surely is one path to better runtime
power management in the Linux kernel. However, I don't like it at all in its
current implementation. Here are a few suggestions for improvements,
rewrites, and so on:
First, the table interface you suggest is ugly.
A small add-on:
We need to make sure that we're capable of handling smart CPUs like Transmeta
Crusoe processors in a sane way. This means

userspace in order to make use of syscalls.

As there have been multiple inquiries on the rationale of my patchsets
removing in-kernel calls to sys_xyzzy(), here is an updated patch 01/NN
which I will push upstream for v4.17

The other one replaces the xorq-based register cleaning with an
equivalent xorl-based version, which is supposed to be faster on
some architectures.
