Summary of test results
test_results_summary_2010R1
mainline framework
Upgrade kernel to 2.6.34
Update real time ADEOS patch to kernel 2.6.34 and update Xenomai to version 2.5.3.
Enable kernel preemption support by doing real task switch while ret from interrupt/exception to kernel space.
Add the PREEMPT_RT patch into distribution as an experimental feature.
Add syscall sys_cacheflush for compiler to deal with trampline user code. It can also be used by applications.
SMP related
Work around IFLUSH anomaly in SMP kernel by run IFLASH in different L1
SRAM on different core.
update kgdb SMP switch core patch to mainline.
Turn IPI message queue list into per cpu static array of 5 elements. This improves the performance under SMP.
Add sleep and sleep deeper PM function for SMP kernel on bf561.
Implement nmi_watchdog for SMP kernel on BF561.
Implement cpu frequency on blackfin SMP
Supporting SMP dynamic percpu_alloc on BF561
Blackfin arch specific
Enable 128/256k/512k uncacheable
DMA memory region for small memory system
Support kernel XIP on NORflash for blackfin in both NOMMU and MPU mode.
Implement ndelay() in Blackfin arch.
Add peripheral group check to detect periphreral function group conflict for bf51x,bf52x and bf537.
Extend memory start to cover init memory. So, access_ok check doesn't report wrong failure.
Changes
Enable interrupt for bfin
SPI bus driver in PIO mode.
Fit bfin sport uart driver into mainline uart inftrastructure and move platform data into board file. Enable hardware flow control via
GPIO PINs.
Work around blackfin MUSB hardware anomalies in MUSB driver.
Work around 32bit
SPORT PIO read/write anomaly in bfin sport uart driver.
Convert ad1836 ALSA driver into ASOC driver. Enable on board ad1836 for bf561-ezkit
Discontinue support for ad1980 driver, since this chip is obsolete.
Move most bfin uart platform data from bfin serial driver into board file. Bind the index of uart device nodes to physical uart port.
Add
API to reorder channel sequence in ASOC and merged by maintainer.
Remove stm_flash driver and switch to common MTD driver.
Support BF518 IEEE 1588 PTP framework in bfin
MAC driver.
BF538/9 PORT C,D,E
GPIO support.
Deduce Ethernet FCS from hardware IPv4 payload checksum in bfin
MAC driver.
Implement streaming
DMA mapping functions in blackfin arch.
Support cable selectable OTG in MUSB driver.
Add
MAC status interrupt handler to bf537, bf527 and bf518.
Enable wake up by Ethernet packet in bfin
MAC driver.
reclaim TX skb as early as possible after EMAC tx transfer. Otherwise, a IP socket may not be closed and freed up in time. Push peripheral pin list to board files. Move PHYINT into mii bus platform data in board file.
Fix wrong raw page read/write flow in bfin
NAND driver.
Convert simple
PPI frame captures demo to use bfin_ppi driver instead of ppi_fcd driver
Enable support for packing in
PPI driver (bfin_ppi). Add 24 bit EPPI mode for bf548
Enable suspend/resume PM functions in MUSB driver. Enable hibernate wakeup from
USB support in MSB driver as well.
Recover from CRC error in
SD read/write operation over
SPI.
Save/restore power state data during suspend/resume. Enable onboard ssm2603 on bf518-ezbrd.
speed up sport RX sample rate to be 3% faster than the normal uart device. Othersize, wrong data are received.
move to mainline
new
input driver for ADXL345/346 Three-Axis Digital Accelerometers
ad1938 ASOC driver with
I2C or
SPI support.
ad7147 capacitor touch sensor driver to support both button and non-button(slider) events
gpiochip driver for adp5588
GPIO expanders
-
Network Driver for ADF7020/21 ISM Narrow-Band Single Chip Transceiver ICs
ADAU1373 ASOC driver.
ADAU1761 ASOC driver.
ADAU1361 ASOC driver.
SIGMA
DSP firmware loader for adau1373 and adau1761 drivers.
ADP8860/70 Blacklight Driver.
add a simple driver for preempt latency test
