2018-10-12ALSA: au88xx: Add fall-through annotationsTakashi Iwai
As a preparatory patch for the upcoming -Wimplicit-fallthrough compiler checks, add the "fall through" annotation in au88xx driver. Although the usages in both both functions vortex_adbdma_setbuffers() and vortex_wtdma_setbuffers() look a bit suspicious, we keep the behavior as before, just to be safer. If it were broken, we should have already received bug reports. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2018-07-27ALSA: au88x0: Fix sparse warning wrt PCM format typeTakashi Iwai
The PCM format type is with __bitwise, and it can't be converted from integer implicitly. Instead of an ugly cast, declare the function argument of vortex_alsafmt_aspfmt() with the proper snd_pcm_format_t type. This fixes the sparse warning like: sound/pci/au88x0/au88x0_core.c:2778:14: warning: restricted snd_pcm_format_t degrades to integer Signed-off-by: Takashi Iwai <tiwai@suse.de>
2017-10-17ALSA: au88x0: remove redundant assignment of variable iColin Ian King

2017-03-24ALSA: au88x0: avoid theoretical uninitialized accessArnd Bergmann
The latest gcc-7.0.1 snapshot points out that we if nr_ch is zero, we never initialize some variables: sound/pci/au88x0/au88x0_core.c: In function 'vortex_adb_allocroute': sound/pci/au88x0/au88x0_core.c:2304:68: error: 'mix[0]' may be used uninitialized in this function [-Werror=maybe-uninitialized] sound/pci/au88x0/au88x0_core.c:2305:58: error: 'src[0]' may be used uninitialized in this function [-Werror=maybe-uninitialized] I assume this can never happen in practice, but adding a check here doesn't hurt either and avoids the warning.

2016-06-29ALSA: au88x0: Fix calculation in vortex_wtdma_bufshift()Takashi Iwai
vortex_wtdma_bufshift() function does calculate the page index wrongly, first masking then shift, which always results in zero. The proper computation is to first shift, then mask.

2016-05-12ALSA: au88x0: Fix zero clear of stream->resourcesTakashi Iwai
There are a few calls of memset() to stream->resources, but they all are called in a wrong size, sizeof(unsigned char) * VORTEX_RESOURCE_LAST, while this field is a u32 array. This may leave the memories not zero-cleared. Fix it by replacing them with a simpler sizeof(stream->resources) instead.

2014-10-15ALSA: au88x0: pr_* replaced with dev_*Sudip Mukherjee
pr_* macros replaced with dev_* as they are more preffered over pr_*. each file which had pr_* was reviewed manually and replaced with dev_*. here we have actually used the reference of the vortex which was added to some functions in the previous patch of this series. The prefix of the CARD_NAME and prefix of "vortex:" was also removed as the dev_* will print the device name.

2014-10-15ALSA: au88x0: added reference of vortex_tSudip Mukherjee
added a pointer of the vortex in the following functions : vortex_alsafmt_aspfmt vortex_Vort3D_InitializeSource a3dsrc_ZeroStateA3D so that we can have a reference of the vortex in the function. this reference of the vortex will actually be used in a later patch to convert the pr_* macro to dev_*.

2014-09-09sound: pci: au88x0: printk replacementSudip Mukherjee

2012-10-25ALSA: au88x0: Give comment for vortex_wtdma_bufshift() issueTakashi Iwai
The check of the return value from vortex_wtdma_bufshft() in vortex_interrupt() is useless as it executes no code. Actually the return value is intentionally ignored because the delta calculation for wavetable doesn't work always correctly. For avoiding the confusion, a comment is added and the superfluous if () is removed. Reported-by: Fengguang Wu <fengguang.wu@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2011-01-19Kill off warning: ‘inline’ is not at beginning of declarationJesper Juhl
Fix a bunch of warning: ‘inline’ is not at beginning of declaration messages when building a 'make allyesconfig' kernel with -Wextra. These warnings are trivial to kill, yet rather annoying when building with -Wextra. The more we can cut down on pointless crap like this the better (IMHO). A previous patch to do this for a 'allnoconfig' build has already been merged. This just takes the cleanup a little further.

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
