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.

2006-09-23[ALSA] es18xx - Add PnP BIOS supportOndrej Zary
This patch adds PnP BIOS support to es18xx driver. It allows ESS ES18xx sound chips integrated in some notebooks (such as DTK FortisPro TOP-5A) that don't appear as ISA cards (they aren't recognized by ISA PnP, only by PnP BIOS) to 'just work' automatically.

2006-03-22[ALSA] #4/4 for Zoom Video - add Zoom Video supportMark Salazar
Modules: ES18xx driver Forth of 4 es18xx.c patches culminating in Zoom Video support. This patch adds Zoom Video support for those chipsets that support it. Testing: This work was initially done on the source from the Debian Sarge ALSA package, then tested on an ES1879. I could not test the Zoom Video function for an ES1878 or ES1869. Patches were created against the Sarge code and then edited to apply correctly to the ALSA cvs code. Lastly the patched ALSA cvs code was test for successful compilation. No additional testing was done on the ALSA cvs version. One quirk (noted in my comments below) is that apparently the datasheet is wrong for one of the ES1879 Zoom Video 'enable' bits, because 1) if you set this bit it messes up PCM playback (speaker_test play a lower frequency) 2) even if you don't set this bit Zoom Video still works. I added a control to toggle the bit on just in case there might be a version of the ES1879 that requires it, but I expect noone will need it.

2006-03-22[ALSA] #3/4 for Zoom Video - change Hardware Volume interrupt handlingMark Salazar
Modules: ES18xx driver Third of 4 es18xx.c patches culminating in Zoom Video support. This patch changes the Hardware Volume support to reflect the fact that not all of the supported chipsets have seperate registers dedicated to the Hardware Volume inputs. Although all the chipsets can generate an HWV interrupt whenever a Hardware Volume input is received only those with seperate HWV registers can split the HWV registers from the Master volume registers. Testing: This work was initially done on the source from the Debian Sarge ALSA package, then tested on an ES1879 and an ES1878 machine. Patches were created against the Sarge code and then edited to apply correctly to the ALSA cvs code. Lastly the patched ALSA cvs code was test for successful compilation.

2006-03-22[ALSA] #2/4 for Zoom Video - resolve number of record sourcesMark Salazar
Modules: ES18xx driver Second of 4 es18xx.c patches culminating in Zoom Video support. This patch changes the 'record source' mux routines to reflect the fact that not all of the supported chipsets have 8 possible inputs. Some have 4 and some have 5. Testing: This work was initially done on the source from the Debian Sarge ALSA package, then tested on an ES1879 and an ES1878 machine. Patches were created against the Sarge code and then edited to apply correctly to the ALSA cvs code. Lastly the patched ALSA cvs code was test for successful compilation.

2006-03-22[ALSA] #1/4 for Zoom Video - resolve common vs chipset specific mixer controlsMark Salazar
Modules: ES18xx driver First of 4 es18xx.c patches culminating in Zoom Video support. While adding support for Zoom Video to the es18xx driver I found some of the mixer controls were wrong. Since you guys went to the trouble of supplying the datasheets for the supported chipsets I did a review of all of them and tried to get es18xx.c to accurately reflect the proper mixer controls for each chipset. If the datasheets are wrong then so are my patches. This first patch moves some controls from the common-to-all-chipsets array 'snd_es18xx_base_controls' to a chipset-specific array and adds code to manage that new array. Also while testing on my ES1878 test machine I discovered it needed a couple of udelays in the identify function so those are in this patch as well. Testing: This work was initially done on the source from the Debian Sarge ALSA package, then tested on an ES1879 and an ES1878 machine. Patches were created against the Sarge code and then edited to apply correctly to the ALSA cvs code. Lastly the patched ALSA cvs code was test for successful compilation.

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!
