The C6X SoCs contain several PLL controllers each with up to 16 clock outputs feeding into the cores or peripheral clock domains. The hardware is very similar to arm/mach-davinci clocks. This is still a work in progress which needs to be updated once device tree clock binding changes shake out. Signed-off-by:

Original port to early 2.6 kernel using TI COFF toolchain. Brought up to date by Mark Salter <msalter@redhat.com> The C6X architecture currently lacks an MMU so memory management is relatively simple. There is no bus snooping between L2 and main memory but coherent DMA memory is supported by making regions of main memory uncached. If such a region is desired, it can be specified on the commandline with a "memdma=" argument. Signed-off-by:

This is the basic devicetree support for C6X. Currently, four boards are supported. Each one uses a different SoC part. Two of the four supported SoCs are multicore. One with 3 cores and the other with 6 cores. There is no coherency between the core-level caches, so SMP is not an option. It is possible to run separate kernel instances on the various cores. There is currently no C6X bootloader support for device trees so we build in the DTB for now. There are some interesting twists to the hardware which are of note for device tree support. Each core has its own interrupt controller which is controlled by special purpose core registers. This core controller provides 12 general purpose prioritized interrupt sources. Each core is contained within a hardware "module" which provides L1 and L2 caches, power control, and another interrupt controller which cascades into the core interrupt controller. These core module functions are controlled by memory mapped registers. The addresses for these registers are the same for each core. That is, when coreN accesses a module-level MMIO register at a given address, it accesses the register for coreN even though other cores would use the same address to access the register in the module containing those cores. Other hardware modules (timers, enet, etc) which are memory mapped can be accessed by all cores. The timers need some further explanation for multicore SoCs. Even though all timer control registers are visible to all cores, interrupt routing or other considerations may make a given timer more suitable for use by a core than some other timer. Because of this and the desire to have the same image run on more than one core, the timer nodes have a "ti,core-mask" property which is used by the driver to scan for a suitable timer to use.

Original port to early 2.6 kernel using TI COFF toolchain. Brought up to date by Mark Salter <msalter@redhat.com> This patch provides the early boot code for C6X architecture. There is a 16 entry vector table which is used to direct reset and interrupt events. The vector table entries contain a small amount of code (maximum of 8 opcodes) which simply branches to the actual event handling code. The head.S code simply clears BSS, setups up a few control registers, and calls machine_init followed by start_kernel. The machine_init code in setup.c does the early flat tree parsing (memory, commandline, etc). At setup_arch time, the code does the usual memory setup and minimally scans the devicetree for any needed information. Signed-off-by:

In summary, this DMI quirk uses the _CRS info by default for the ASUS M2V-MX SE by turning on `pci=use_crs` and is similar to the quirk added by commit 2491762c ("x86/PCI: use host bridge _CRS info on ASRock ALiveSATA2-GLAN") whose commit message should be read for further information.

This resolves a regression seen by some users of bridging. Some users use the bridge like a dummy device. They expect to be able to put an IPv6 address on the device with no ports attached. Although there are better ways of doing this, there is no reason to not allow it. Note: the bridge still will reflect the state of ports in the bridge if there are any added. Signed-off-by:

lost_skb_hint is used by tcp_mark_head_lost() to mark the first unhandled skb. lost_cnt_hint is the number of packets or sacked packets before the lost_skb_hint; When shifting a skb that is before the lost_skb_hint, if tcp_is_fack() is ture, the skb has already been counted in the lost_cnt_hint; if tcp_is_fack() is false, tcp_sacktag_one() will increase the lost_cnt_hint. So tcp_shifted_skb() does not need to adjust the lost_cnt_hint by itself. When shifting a skb that is equal to lost_skb_hint, the shifted packets will not be counted by tcp_mark_head_lost(). So tcp_shifted_skb() should adjust the lost_cnt_hint even tcp_is_fack(tp) is true. Signed-off-by:

Add the ability to disable PCI-E MPS turning and using the BIOS configured MPS defaults. Due to the number of issues recently discovered on some x86 chipsets, make this the default behavior. Also, add the option for peer to peer DMA MPS configuration. Peer to peer DMA is outside the scope of this patch, but MPS configuration could prevent it from working by having the MPS on one root port different than the MPS on another. To work around this, simply make the system wide MPS the smallest possible value (128B). Signed-off-by:

Most asics just use the hw default value which requires no explicit programming. For those that need a different value, the vbios will program it properly. As such, there's no need to program these registers explicitly in the driver. Changing MC_SHARED_CHREMAP requires a reload of all data in vram otherwise its contents will be scambled.
