Balaji and Sean, is there something we can do to integrate this patch?
For example platform callback to implement the action in mach_gta02.c
and just take on the interrupt mapping and private data? Would it need
to have the functionality enabled by /sys or somesuch because it muddles
up the normal semantics?
I know we want to see everything into the kernel for Android, but I'm
not sure if this is desired. It would most certainly impact how things
work on other distros and there should be a way to deal with it inside
of Android. I just haven't found it yet. If we do want to add it in for
the time being, then yeah a /sys switch to change the default behavior
would work. I can writeup a change to add that. I'm not sure if my
change is 100% correct, for that matter, as I can't get shutdown if I
hold the key for 8 seconds or longer.
On the config, the diff between this and the gta02 moredrivers one are
these:
Just changes to built-in from module already (fine):
- -CONFIG_CRC_CCITT=m
+CONFIG_CRC_CCITT=y
- -CONFIG_CRYPTO_ARC4=m
+CONFIG_CRYPTO_ARC4=y
- -CONFIG_CRYPTO_ECB=m
+CONFIG_CRYPTO_ECB=y
- -CONFIG_CRYPTO_SHA1=m
+CONFIG_CRYPTO_SHA1=y
- -CONFIG_TUN=m
+CONFIG_TUN=y
- -CONFIG_SLHC=m
+CONFIG_SLHC=y
- -CONFIG_PPP_ASYNC=m
- -CONFIG_PPP_BSDCOMP=m
- -CONFIG_PPP_DEFLATE=m
+CONFIG_PPP_ASYNC=y
+CONFIG_PPP_BSDCOMP=y
+CONFIG_PPP_DEFLATE=y
- -CONFIG_PPP=m
- -CONFIG_PPP_MPPE=m
+CONFIG_PPP_MPPE=y
- -CONFIG_PPP_SYNC_TTY=m
+CONFIG_PPP_SYNC_TTY=y
+CONFIG_PPP=y
Great. These might change further when I manage to get GPRS working for
real. Still not quite there yet.
NFS support (fine)
+CONFIG_NETWORK_FILESYSTEMS=y
+CONFIG_NFS_COMMON=y
+CONFIG_NFS_FS=y
+CONFIG_SUNRPC=y
+CONFIG_LOCKD=y
This is only really needed for testing with a chroot environment. Not
necessary for typical use.
Kill Framebuffer console add logo:
- -CONFIG_FONT_6x11=y
- -CONFIG_FONTS=y
- -CONFIG_FRAMEBUFFER_CONSOLE=y
+CONFIG_LOGO_OPENMOKO_CLUT224=y
+CONFIG_LOGO=y
New / changed features (fine):
- -CONFIG_NR_TTY_DEVICES=4
+CONFIG_NR_TTY_DEVICES=6
Prefer existing setting (shouldn't impact)
- -CONFIG_USB_S3C2410_DEBUG=y
- -CONFIG_LOG_BUF_SHIFT=18
+CONFIG_LOG_BUF_SHIFT=17
- -CONFIG_MMC_BLOCK_BOUNCE=y
Yes, agreed.
So I can change to all of these except the last ones which I don't think
matter for Android, and the "kill framebuffer and add logo" stuff...
what happens if we leave the framebuffer console support in for Android,
something bad?
With the console support and log messages that come out of both Android
and the kernel it causes serious visual issues. Constant flipping back
to the console to display logs and then it usually doesn't repaint
properly when it goes back.
