2021-03-18ALSA: ctxfi: fix comment syntax in file headersAditya Srivastava1-1/+1
The opening comment mark '/**' is used for highlighting the beginning of kernel-doc comments. There are files in sound/pci/ctxfi which follow this syntax in their file headers, i.e. start with '/**' like comments, which causes unexpected warnings from kernel-doc. E.g., running scripts/kernel-doc -none on sound/pci/ctxfi/ctresource.c causes this warning: "warning: wrong kernel-doc identifier on line: * Copyright (C) 2008, Creative Technology Ltd. All Rights Reserved." Similarly for other files too. Provide a simple fix by replacing the kernel-doc like comment syntax with general format, i.e. "/*", to prevent kernel-doc from parsing it.

2011-08-24ALSA: ctxfi: Bump playback substreams to 256Maarten Lankhorst1-1/+1
There are references in the code to 256 sources, so I tested it with 256 aplays, of which the first and last with real data and the rest playing /dev/zero . Also increase amount of page tables, so the default aplay size works. Signed-off-by: Maarten Lankhorst <m.b.lankhorst@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2010-02-04ALSA: ctxfi - fix PTP address initializationJaroslav Kysela1-3/+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.

Use SG-buffers instead of contiguous pages. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-02ALSA: ctxfi - Remove PAGE_SIZE limitationTakashi Iwai1-0/+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>
