* ALSA: ctxfi - fix PTP address initializationJaroslav Kysela2010-02-041-3/+5
| | | | | | | | | | | After hours of debugging, I finally found the reason why some source and runtime combination does not work. The PTP (page table pages) address must be aligned. I am not sure how much, but alignment to PAGE_SIZE is sufficient. Also, use ALSA's page allocation routines to ensure proper virtual -> physical address translation.

* ALSA: ctxfi - Remove PAGE_SIZE limitationTakashi Iwai2009-06-021-0/+8
| | | | | | | | | | Remove the limitation of PAGE_SIZE to be 4k by defining the own page size and macros for 4k. 8kb page size could be natively supported, but it's disabled right now for simplicity. Also, clean up using upper_32_bits() macro. Signed-off-by: Takashi Iwai <tiwai@suse.de>
