The function probe_tlb() only does anything for processors that are not PRID_COMP_LEGACY. This is precisely the set of processors for which decode_configs() is called to do identical tlbsize probing calculations. Therefore probe_tlb() is completely redundant and may be removed. Signed-off-by:

MIPS currently lacks the readl_be and writel_be accessors which are required by BCM63xx for OHCI and EHCI support. Let's define them globally for MIPS. This also fixes the compilation of the bcm63xx defconfig against USB. Signed-off-by:

Changes: o Serial port related configuration Disable EARLY_PRINTK, CONFIG_SYS_SUPPORTS_ZBOOT_UART16550 Enable the serial port support as module. o PM related support Enable CPUFreq as module, use the external timer(MFGPT) instead of r4k timer. Enable Suspend support Enable Run Time PM support o Enable SM7XX Video Driver Disable the buggy 2d acceleration o Enable CONFIG_OPROFILE as module o Use GZIP instead of LZMA, which need less decompression time o Enable more USB devices support o Enable initrd support(needed by gNewsense) o Enable more crypto support Signed-off-by:Wu Zhangjin <wuzhangjin@gmail.com> Cc: linux-mips@linux-mips.org Cc: yanh@lemote.com Cc: huhb@lemote.com Cc: zhangfx@lemote.com Patchwork: http://patchwork.linux-mips.org/patch/830/Signed-off-by:

The compressed kernel support on loongson family machines is stable now, so, remove the debug information via using SYS_SUPPORTS_ZBOOT instead of SYS_SUPPORTS_ZBOOT_UART16550. This may reduce the image size and speedup the booting. Signed-off-by:

Lemote have used the PMON_VER strings to indicate the loongson-2f machine series: PMON_VER=LM8089 Lemote 8.9'' netbook LM8101 Lemote 10.1'' netbook (The above two netbooks have the same kernel support) LM6XXX Lemote FuLoong(2F) box series LM9XXX Lemote LynLoong PC series Before the machtype is supported by the PMON, we can get the machine type from the PMON_VER for these machines, this will help the users a lot.

Octeon ethernet hardware can handle NETIF_F_SG, so we enable it. A gather list of up to six fragments will fit in the SKB's CB structure, so no extra memory is required. If a SKB has more than six fragments, we must linearize it. Signed-off-by:

Convert the driver to be a reasonably well behaved NAPI citizen. There is one NAPI instance per CPU shared between all input ports. As receive backlog increases, NAPI is scheduled on additional CPUs. Receive buffer refill code factored out so it can also be called from the periodic timer. This is needed to recover from temporary buffer starvation conditions. Signed-off-by:

David Daney authored
After aligning the blocks returned by kmalloc, we need to save the original pointer so they can be correctly freed. There are no guarantees about the alignment of SKB data, so we need to handle worst case alignment. Since right shifts over subtraction have no distributive property, we need to fix the back pointer calculation. Signed-off-by:

If an interrupt handler disables interrupts, the EOI function will just reenable them. This will put us in an endless loop when the upcoming Ethernet driver patches are applied. Only reenable the interrupt on EOI if it is not IRQ_DISABLED. This requires that the EOI function be separate from the ENABLE function. We also rename the ACK functions to correspond with their function. Signed-off-by:

In order to achieve correct synchronization semantics, the Octeon port had defined CONFIG_WEAK_REORDERING_BEYOND_LLSC. This resulted in code that looks like: sync ll ... . . . sc ... . . sync The second SYNC was redundant, but harmless. Octeon has a SYNCW instruction that acts as a write-memory-barrier (due to an erratum in some parts two SYNCW are used). It is much faster than SYNC because it imposes ordering on the writes, but doesn't otherwise stall the execution pipeline. On Octeon, SYNC stalls execution until all preceeding writes are committed to the coherent memory system. Using: syncw;syncw ll . . . sc . . Has identical semantics to the first sequence, but is much faster. The SYNCW orders the writes, and the SC will not complete successfully until the write is committed to the coherent memory system. So at the end all preceeding writes have been committed. Since Octeon does not do speculative reads, this functions as a full barrier. The patch removes CONFIG_WEAK_REORDERING_BEYOND_LLSC, and substitutes SYNCW for SYNC in write-memory-barriers. Signed-off-by: -

Replace some instances of smp_llsc_mb() with a new macro smp_mb__before_llsc(). It is used before ll/sc sequences that are documented as needing write barrier semantics. The default implementation of smp_mb__before_llsc() is just smp_llsc_mb(), so there are no changes in semantics. Also simplify definition of smp_mb(), smp_rmb(), and smp_wmb() to be just barrier() in the non-SMP case. Signed-off-by:

For 64-bit kernels with 64KB pages and two level page tables, there are 42 bits worth of virtual address space This is larger than the 40 bits of virtual address space obtained with the default 4KB Page size and three levels, so there are no draw backs for using two level tables with this configuration.

This patch converts the au1000-eth driver to become a full platform-driver as it ought to be. We now pass PHY-speficic configurations through platform_data but for compatibility the driver still assumes the default settings (search for PHY1 on MAC0) when no platform_data is passed. Tested on my MTX-1 board. Signed-off-by:

Limit the amount of address space claimed for Alchemy serial ports to 0x1000. On the Au1300, ports are only 0x1000 apart, and the registers only extend to 0x110 at most on all supported alchemy models. On the Au1300 the autodetect logic no longer works and this makes it necessary to specify the port type through platform data. Because of this the MSR quirk needs to be moved outside the autoconfig() function which will no longer be called when UPF_FIXED_TYPE is specified. Signed-off-by:
