* [ALSA] alsa core: add struct device pointer to struct snd_pcmJohannes Berg2007-02-09
| | | | | | | | | | | This patch adds a struct device pointer to struct snd_pcm in order to be able to give it a different device than the card. It defaults to the card's device, however, so it should behave identically for drivers not touching the field.

Current patch fixes it, as well as other inconsistencies expressed, that do not permit targets from working properly: - Updated dts with a chosen node with interrupt controller, - fixed messed device IDs among CPM2 SoC devices, - corrected odd header name and fixed type in defines, - Added 82xx subdir to the powerpc/platforms Makefile, missed during initial commit, - new solely-powerpc header file for 8260 family (was using one from arch/ppc, this one cleaned up from the extra stuff), in fact for now a placeholder to get the board-specific includes for stuff not yet capable to live with devicetree peeks only - Fixed couple of misprints in reference mpc8272 dts.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This contains important fixes for the CPM2 PIC code. Eliminated CPM_IRQ_OFFSET, pulling the respective interrupt numbers from the interrupt mapping. Updated devicetree files to reflect that. Changed direct IC-related IO accesses to the IO accessors. Fixed all the sense values to keep coherency with ipic. In the current code, CPM2 stuff will have no IRQs and hence could be hardly usable.

Upon closer inspection ld.so was loaded at 0x8000000 (128MB) with the heap right after it. Since we normally link binaries at 0x10000000 (256MB) we only had about 128MB of space for the heap: 00100000-00103000 r-xp 00100000 00:00 0 [vdso] 08000000-0801e000 r-xp 00000000 00:01 33079 /lib/ld-2.5.so 0802d000-0802f000 rwxp 0001d000 00:01 33079 /lib/ld-2.5.so 0802f000-08050000 rwxp 0802f000 00:00 0 [heap] 0fe91000-0ffd9000 r-xp 00000000 00:01 33082 /lib/libc-2.5.so 0ffd9000-0ffe8000 ---p 00148000 00:01 33082 /lib/libc-2.5.so 0ffe8000-0ffea000 r--p 00147000 00:01 33082 /lib/libc-2.5.so 0ffea000-0ffed000 rwxp 00149000 00:01 33082 /lib/libc-2.5.so 10000000-10004000 r-xp 00000000 00:01 76 /bin/sleep 10013000-10014000 rwxp 00003000 00:01 76 /bin/sleep ffb41000-ffb56000 rw-p ffb41000 00:00 0 [stack] One way to fix this is move ELF_ET_DYN_BASE from 0x08000000 to 0x20000000. This allows 128MB for the binary (hopefully enough for even the most crazy c++ apps), and with our current layout we will grow the heap up and the stack down, allowing potentially gigabytes of heap: 00100000-00103000 r-xp 00100000 00:00 0 [vdso] 0fe8a000-0ffd3000 r-xp 00000000 00:01 3350 /lib/tls/libc-2.3.6.so 0ffd3000-0ffe3000 ---p 00149000 00:01 3350 /lib/tls/libc-2.3.6.so 0ffe3000-0ffea000 r--p 00149000 00:01 3350 /lib/tls/libc-2.3.6.so 0ffea000-0ffee000 rwxp 00150000 00:01 3350 /lib/tls/libc-2.3.6.so 10000000-10004000 r-xp 00000000 00:01 76 /bin/sleep 10013000-10014000 rwxp 00003000 00:01 76 /bin/sleep 20000000-20018000 r-xp 00000000 00:01 3478 /lib/ld-2.3.6.so 20028000-20029000 r--p 00018000 00:01 3478 /lib/ld-2.3.6.so 20029000-2002a000 rwxp 00019000 00:01 3478 /lib/ld-2.3.6.so 2002a000-2004b000 rwxp 2002a000 00:00 0 [heap] ffd67000-ffd7c000 rw-p ffd67000 00:00 0 [stack] Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
