* Fix Blackfin HARDWARE_PM supportMathieu Desnoyers2008-01-151-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch restores the blackfin Hardware Performance Monitor Profiling support that was killed by the combining of instrumentation menus in commit 09cadedbdc01f1a4bea1f427d4fb4642eaa19da9. Since there seems to be no good reason to behave differently from other architectures, it now automatically selects the hardware performance counters whenever the profiling is activated. mach-common/irqpanic.c: pm_overflow calls pm_overflow_handler which is in oprofile/op_model_bf533.c. I doubt that setting HARDWARE_PM as "m" will work at all, since the pm_overflow_handler should be in the core kernel image because it is called by irqpanic.c. Therefore, I change HARDWARE_PM from a tristate to a bool. The whole arch/$(ARCH)/oprofile/ is built depending on CONFIG_OPROFILE. Since part of the HARDWARE_PM support files sits in this directory, it makes sense to also depend on OPROFILE, not only PROFILING. Since OPROFILE already depends on PROFILING, it is correct to only depend on OPROFILE only. Thanks to Adrian Bunk for finding this bug and providing an initial patch.

* Blackfin arch: fix bug kernel not to boot up with mtd filesystemsBernd Schmidt2007-11-183-33/+24
| | | | | | | | | | | | | | | | Revert this patch: move the init sections to the end of memory, so that after they are free, run time memory is all continugous - this should help decrease memory fragementation. When doing this, we also pack some of the other sections a little closer together, to make sure we don't waste memory. To make this happen, we need to rename the .data.init_task section to .init_task.data, so it doesn't get picked up by the linker script glob. Since it causes the kernel not to boot up with mtd filesystems. Signed-off-by: Bernd Schmidt <bernd.schmidt@analog.com> Signed-off-by: Bryan Wu <bryan.wu@analog.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | /* * CPUs often take a performance hit when accessing unaligned memory * locations. The actual performance hit varies, it can be small if the * hardware handles it or large if we have to take an exception and fix * it * in software. * * Since an ethernet header is 14 bytes network drivers often end up * with * the IP header at an unaligned offset. The IP header can be aligned by * shifting the start of the packet by 2 bytes. Drivers should do this * with: * * skb_reserve(NET_IP_ALIGN); * * The downside to this alignment of the IP header is that the DMA is * now * unaligned. On some architectures the cost of an unaligned DMA is high * and this cost outweighs the gains made by aligning the IP header. * * Since this trade off varies between architectures, we allow * NET_IP_ALIGN * to be overridden. */ This new function insl_16 allows to read form 32-bit IO and writes to 16-bit aligned memory. This is useful in above described scenario - In particular with the AXIS AX88180 Gigabit Ethernet MAC. Once the device is in 32-bit mode, reads from the RX FIFO always decrements 4bytes. While on the other side the destination address in SDRAM is always 16-bit aligned. If we use skb_reserve(0) the receive buffer is 32-bit aligned but later we hit a unaligned exception in the IP code.
