CRIS v10: vmlinux.lds.S: ix kernel oops on boot and use common defines

2008-01-17T23:38:58+00:00

- Move alignment to page size of init data outside ifdef for BLK_DEV_INITRD.
  The reservation up to page size of memory after init data was previously
  not done if BLK_DEV_INITRD was undefined.
  This caused a kernel oops when init memory pages were freed after startup,
  data placed in the same page as the last init memory would also be freed
  and reused, with disastrous results.

- Use macros for initcalls and .text sections.

- Replace hardcoded page size constant with PAGE_SIZE define.

- Change include/asm-cris/page.h to use the _AC macro to instead
  of testing __ASSEMBLY__.

CRIS: define __ARCH_WANT_SYS_RT_SIGSUSPEND in unistd.h for CRIS

2008-01-14T16:52:23+00:00

This allows us to use the commong sys_rt_sigsuspend instead of
having our own.

CRIS tlb.h should include linux/pagemap.h

2007-11-15T02:45:47+00:00

Include linux/pagemap.h for release_pages and page_cache_release.

Fixes compilation error in arch/cris/mm/init.c when CONFIG_SWAP is unset.

CRISv10 improve and bugfix fasttimer

2007-11-15T02:45:47+00:00

Improve and bugfix CRIS v10 fast timers.

- irq_handler_t now only takes two arguments.
- Keep interrupts disabled as long as we have a reference to the
  fasttimer list and only enable them while doing the callback.
  del_fast_timer may be called from other interrupt context.
- Fix bug where debug code could return without calling local_irq_restore.
- Use jiffies instead of usec (change from struct timeval to fasttime_t).
- Don't initialize static variables to zero.
- Remove obsolete #ifndef DECLARE_WAITQUEUE code.
- fast_timer_init should be __initcall.
- Change status/debug variables to unsigned.
- Remove CVS log and CVS id.

cris build fixes: corrected and improved NMI and IRQ handling

2007-11-15T02:45:45+00:00

Corrects compile errors and the following:

- Remove oldset parameter from do_signal and do_notify_resume.

- Modified to fit new consolidated IRQ handling code.

- Reverse check order between external nmi and watchdog nmi to avoid false
  watchdog oops in case of a glitch on the nmi pin.

- Return from an pin-generated NMI the same way as for other interrupts.

- Moved blocking of ethernet rx/tx irq from ethernet interrupt handler to
  low-level asm interrupt handlers.  Fixed in the multiple interrupt
  handler also.

- Add space for thread local storage in thread_info struct.

- Add NO_DMA to Kconfig, and include arch specific Kconfig using arch
  independent path. Include subsystem Kconfigs for pcmcia, usb, i2c,
  rtc and pci.

cris build fixes: update eth_v10.c ethernet driver

2007-11-15T02:45:45+00:00

New (updated) version of ethernet driver for cris v10.

- First steps to simplify and make the MII code more similar
  between the etrax100 and etraxfs ports.

- Start the transmit queue before enabling tx interrupts
  to avoid race with the first frame.

- Flip the comparition statement to stick to physical addresses
  to avoid phys_to_virt mapping a potential null pointer.
  This was not an error but the change simplifies debugging
  of address-space mappings.

- Made myPrevRxDesc local to e100_rx since it was only used there.
  Fixed out of memory handling in e100_rx.  If dev_alloc_skb() fails
  persistently the system is hosed anyway but at least it won't
  loop in an interrupt handler.

- Correct some code formatting issues.

- Add defines SET_ETH_ENABLE_LEDS, SET_ETH_DISABLE_LEDS
  and SET_ETH_AUTONEG used in new cris v10 ethernet driver.
