#5187 closed enhancement (fixed)

b43 firmware : lot's of useless file

Reported by: castet.matthieu@… Owned by: hauke
Priority: normal Milestone: Barrier Breaker 14.07
Component: packages Version: Trunk
Keywords: Cc:


the firmware in /lib/firmware/b43 (and /lib/firmware/b43legacy) contains lot's of file not used by the b43 driver.

A cleanup could help save some flash memory.

PS :
current b43 driver use :
$grep "filename =" main.c | grep -e ucode -e initvals -e pcm

filename = "ucode5";
filename = "ucode11";
filename = "ucode13";
filename = "pcm5";

filename = "a0g1initvals5";
filename = "a0g0initvals5";

filename = "b0g0initvals5";
filename = "b0g0initvals13";
filename = "n0initvals11";

filename = "a0g1bsinitvals5";
filename = "a0g0bsinitvals5";

filename = "b0g0bsinitvals5";
filename = "n0bsinitvals11";

on the target we have :
# ls /lib/firmware/b43/
a0g0bsinitvals4.fw b0g0bsinitvals4.fw n0absinitvals11.fw
a0g0bsinitvals5.fw b0g0bsinitvals5.fw n0bsinitvals11.fw
a0g0bsinitvals9.fw b0g0bsinitvals9.fw n0initvals11.fw
a0g0initvals4.fw b0g0initvals13.fw pcm4.fw
a0g0initvals5.fw b0g0initvals4.fw pcm5.fw
a0g0initvals9.fw b0g0initvals5.fw ucode11.fw
a0g1bsinitvals13.fw b0g0initvals9.fw ucode13.fw
a0g1bsinitvals5.fw lp0bsinitvals13.fw ucode14.fw
a0g1bsinitvals9.fw lp0bsinitvals14.fw ucode15.fw
a0g1initvals13.fw lp0bsinitvals15.fw ucode4.fw
a0g1initvals5.fw lp0initvals13.fw ucode5.fw
a0g1initvals9.fw lp0initvals14.fw ucode9.fw
b0g0bsinitvals13.fw lp0initvals15.fw

  • Resolution set to invalid

Use "Remove unnecessary firmware files" in menu it was already fixed in r14929.

That's not really fixed by r14929 :
r14929 : allow to remove firmware files by chipset revision. The default behaviour is to include them all.
But by default we should only include firmware supported by b43 driver.
There no point in adding for example ucode4.fw that will never load by b43 driver.

This can be done for example running squash utility with all chipset supported by b43 driver : "5,6,7,8,9,10,11,12,13"

Also the same should be done for b43legacy.

please reopen it
