Michael Sevakis 12375d1d3a Merge functionality of wakeups and semaphores-- fewer APIs and object types. semaphore_wait takes a timeout now so codecs and plugins have to be made incompatible. Don't make semaphores for targets not using them.

gigabeat-s Merge functionality of wakeups and semaphores-- fewer APIs and object types. semaphore_wait takes a timeout now so codecs and plugins have to be made incompatible. Don't make semaphores for targets not using them. 2011-03-02 08:49:38 +00:00
app.lds Some static data is only used by .init functions. Add .initdata to declare such data (otherwise section conflicts arise). For i.MX31, use INITDATA_ATTR in the appropriate places. 2011-01-08 20:42:51 +00:00
ata-imx31.c Merge functionality of wakeups and semaphores-- fewer APIs and object types. semaphore_wait takes a timeout now so codecs and plugins have to be made incompatible. Don't make semaphores for targets not using them. 2011-03-02 08:49:38 +00:00
ata-target.h i.MX31: Busy wait for a couple microseconds at most then sleep until next tick when polling drive status. This prevents pointless jumps to overdrive speed from perceived high load when waiting for lengthy ops to complete such as spinup and sleep. 2011-01-22 09:23:31 +00:00
avic-imx31.c Configure Gigabeat S with EABI compiler by default. Implement the INIT section that this enables (due to selective need for long calls). Remove pcm_postinit from INIT section since it's asynchronous. Disable strict aliasing on SPC codec for now just to shut it up. 2010-06-11 14:39:35 +00:00
avic-imx31.h Gigabeat S/i.MX31: Take care of an interrupt priority inversion that can happen during PCM callback lockout when DVFS switches frequecies during the lockout, preventing a thread from unlocking the callback until DVFS finishes, causing an SSI FIFO underrun. Hadn't thought of an acceptable way to deal with it before. 2011-01-07 20:40:36 +00:00
boot.lds Some static data is only used by .init functions. Add .initdata to declare such data (otherwise section conflicts arise). For i.MX31, use INITDATA_ATTR in the appropriate places. 2011-01-08 20:42:51 +00:00
ccm-imx31.c Remove atomic register bit manipulation functions from i.MX and s3c target code and introduce generic functions for ARM (bitmod32, bitset32, and bitclr32). Multiprocessor support is possible but just not implemented at the moment, only interrupt lockout. 2010-06-30 02:02:46 +00:00
ccm-imx31.h i.MX31/Gigabeat S: Implement frequency and voltage scaling-- 1.6V for 528MHz, and 1.35V for 264MHz and 132MHz. Keep DPTC overdrive ( > 400MHz) voltage scaling off for now because of uncertainties. Simplify the (working) mess later. 2010-04-23 15:32:50 +00:00
crt0.S Gigabeat S: Renovate bootloader a bit to show splash, implement verbose, shutdown on low battery, handle hold-switch-on and wait only so long for USB if a USB charger is inserted at boot instead of being connected to a host. 'Bootloader USB mode' display is just part of normal printf stream now. Move interrupt stacks into .bss area so they aren't loaded (for firmware too). 2011-01-21 07:05:51 +00:00
debug-imx31.c i.MX31: Add a debug menu to play around with DVFS/DPTC settings for fun, testing or benchmarking purposes. Can set the CPU frequency working point, whether DPTC voltage scaling is enabled and change the software-programmable load tracking weights. 2011-01-22 16:58:17 +00:00
debug-target.h i.MX31: Add a debug menu to play around with DVFS/DPTC settings for fun, testing or benchmarking purposes. Can set the CPU frequency working point, whether DPTC voltage scaling is enabled and change the software-programmable load tracking weights. 2011-01-22 16:58:17 +00:00
dvfs_dptc-imx31.c i.MX31: Now that it matters because there's a debug screeen that allows changing things while running, some DVFS/DPTC stuff has to be done more carefully. Trim out some stuff and group functions better as well. 2011-01-23 20:21:35 +00:00

gpio-imx31.h i.MX31/Gigabeat S minor cleaning: Make HW access more obvious in places I forgot to do earlier. Reduce the number of structs that need to be filled-out for some drivers just to simplify a little. Change some types. 2010-05-07 10:53:19 +00:00
i2c-imx31.c Merge functionality of wakeups and semaphores-- fewer APIs and object types. semaphore_wait takes a timeout now so codecs and plugins have to be made incompatible. Don't make semaphores for targets not using them. 2011-03-02 08:49:38 +00:00
i2c-imx31.h i.MX31: Make some style changes to some driver code so that hardware vs. variable access is more obvious to the eye. Change a few data types and qualifiers. No functional differences. 2010-05-07 02:29:18 +00:00
iomuxc-imx31.c Remove atomic register bit manipulation functions from i.MX and s3c target code and introduce generic functions for ARM (bitmod32, bitset32, and bitclr32). Multiprocessor support is possible but just not implemented at the moment, only interrupt lockout. 2010-06-30 02:02:46 +00:00
iomuxc-imx31.h i.MX31: Add some enums and a couple helper functions to make dealing with pin muxing and pad configuration a bit more sane. Convert any existing code which changes mux/pad settings to use helpers. 2010-04-23 13:46:04 +00:00
mc13783-imx31.c Merge functionality of wakeups and semaphores-- fewer APIs and object types. semaphore_wait takes a timeout now so codecs and plugins have to be made incompatible. Don't make semaphores for targets not using them. 2011-03-02 08:49:38 +00:00
mmu-imx31.c Gigabeat S/i.MX31: Sort files in the /target tree into things that are SoC-generic (into /imx31) and player-specific (into /gigabeat-s, based upon current appearances). Move i2s clock init into the appropriate file. Housekeeping only-- no functional changes. 2010-04-09 01:21:53 +00:00
mmu-imx31.h Gigabeat S/i.MX31: Sort files in the /target tree into things that are SoC-generic (into /imx31) and player-specific (into /gigabeat-s, based upon current appearances). Move i2s clock init into the appropriate file. Housekeeping only-- no functional changes. 2010-04-09 01:21:53 +00:00
rolo_restart_firmware.S Introduce NORETURN_ATTR wrapper for __attribute__((noreturn)), using this and a bit further cleanup in main gets rid of a warning when compiling for android. 2010-08-12 13:38:25 +00:00
sdma-imx31.c i.MX31: Make DMA ISR call loop a bit more efficient. 2010-06-30 07:08:10 +00:00
sdma-imx31.h Gigabeat S: Implement MDMA and UDMA disk access for bootloader and main binary. Add a needed SDMA API to check channel errors. Increase audio DMA channels' priority as required. Reads and writes measure faster accross all test_disk tests and especially at 4KB and 1MB. 2009-03-12 06:31:40 +00:00
sdma_script_code.h Some static data is only used by .init functions. Add .initdata to declare such data (otherwise section conflicts arise). For i.MX31, use INITDATA_ATTR in the appropriate places. 2011-01-08 20:42:51 +00:00
sdma_struct.h Fix tabs 2010-01-03 10:19:43 +00:00
serial-imx31.h Gigabeat S/i.MX31: Sort files in the /target tree into things that are SoC-generic (into /imx31) and player-specific (into /gigabeat-s, based upon current appearances). Move i2s clock init into the appropriate file. Housekeeping only-- no functional changes. 2010-04-09 01:21:53 +00:00

spi-imx31.h Gigabeat S: Implement LCD contrast, invert and flip modes. Enhance LCD power management. Include init data but it's not needed yet (identical to Gigabeat F). 2010-05-18 23:50:00 +00:00
