* PCI: Set PCI-E Max Payload Size on fabricJon Mason2011-08-013-44/+213
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On a given PCI-E fabric, each device, bridge, and root port can have a different PCI-E maximum payload size. There is a sizable performance boost for having the largest possible maximum payload size on each PCI-E device. However, if improperly configured, fatal bus errors can occur. Thus, it is important to ensure that PCI-E payloads sends by a device are never larger than the MPS setting of all devices on the way to the destination. This can be achieved two ways: - A conservative approach is to use the smallest common denominator of the entire tree below a root complex for every device on that fabric. This means for example that having a 128 bytes MPS USB controller on one leg of a switch will dramatically reduce performances of a video card or 10GE adapter on another leg of that same switch. It also means that any hierarchy supporting hotplug slots (including expresscard or thunderbolt I suppose, dbl check that) will have to be entirely clamped to 128 bytes since we cannot predict what will be plugged into those slots, and we cannot change the MPS on a "live" system. - A more optimal way is possible, if it falls within a couple of constraints: * The top-level host bridge will never generate packets larger than the smallest TLP (or if it can be controlled independently from its MPS at least) * The device will never generate packets larger than MPS (which can be configured via MRRS) * No support of direct PCI-E <-> PCI-E transfers between devices without some additional code to specifically deal with that case Then we can use an approach that basically ignores downstream requests and focuses exclusively on upstream requests. In that case, all we need to care about is that a device MPS is no larger than its parent MPS, which allows us to keep all switches/bridges to the max MPS supported by their parent and eventually the PHB. In this case, your USB controller would no longer "starve" your 10GE Ethernet and your hotplug slots won't affect your global MPS. Additionally, the hotplugged devices themselves can be configured to a larger MPS up to the value configured in the hotplug bridge. To choose between the two available options, two PCI kernel boot args have been added to the PCI calls. "pcie_bus_safe" will provide the former behavior, while "pcie_bus_perf" will perform the latter behavior. By default, the latter behavior is used. NOTE: due to the location of the enablement, each arch will need to add calls to this function. This patch only enables x86. This patch includes a number of changes recommended by Benjamin Herrenschmidt.

This allows dss.c to dump the clock information for all the clocks. With pm_runtime this is no longer the case, as each submodule will handle its clocks independently.

The current code only handles OMAP2/3 case, and so the values are a bit off for OMAP4. A summary of the differences between OMAP2/3 and OMAP4: Burst size: OMAP2/3: 4 x 32 bits / 8 x 32 bits / 16 x 32 bits OMAP4: 2 x 128 bits / 4 x 128 bits / 8 x 128 bits Threshold size: OMAP2/3: in bytes (8 bit units) OMAP4: in 128bit units This patch fixes the issue by creating two new helper functions in dss_features: dss_feat_get_buffer_size_unit() and dss_feat_get_burst_size_unit(). These return (in bytes) the unit size for threshold registers and unit size for burst size register, respectively, and are used to calculate correct values. For the threshold size the usage is straightforward. However, the burst size register has different multipliers for OMAP2/3 and OMAP4. This patch solves the problem by defining the multipliers for the burst size as 2x, 4x and 8x, which fit fine for the OMAP4 burst size definition (i.e. burst size unit for OMAP4 is 128bits), but requires a slight twist on OMAP2/3 by defining the burst size unit as 64bit. As the driver in practice always uses the maximum burst size, and no use case currently exists where we would want to use a smaller burst size, this patch changes the driver to hardcode the burst size when initializing DISPC. This makes the threshold configuration code somewhat simpler. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

The update mode can be changed via OMAPFB_SET_UPDATE_MODE ioctl, which previously called omapdss but is now handled inside omapfb, and a new sysfs file, "update_mode". The update interval is by default 20 times per second, but can be changed via "auto_update_freq" module parameter. There is also a new module parameter "auto_update", which will make omapfb start manual update displays in auto-update mode. This auto-update mode can be used for testing if the userspace does not support manual update displays properly. However, it is a very inefficient solution, and should be considered more as a hack for testing than something that could be used as a long term solution.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Presently these were all using the same static string with no regard to dev_name() and the like. This implements a bit of rework to name the IRQ dynamically, as it should have been doing all along anyways. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ultimately we want everything to be going through the clock framework and runtime pm, so kill off the per-port callbacks that enabled ports to bypass the common infrastructure.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This V2 patch changes the clock disabling behavior during boot. Two different changes are made: 1) Delay disabling of clocks until late in the boot process. This fixes an existing issue where in-use clocks without software reference are disabled by mistake during boot. One example of this is the handling of the Mackerel serial console output that shares clock with the I2C controller. 2) Write out the "disabled" state to the hardware for clocks that not have been used by the kernel. In other words, make sure so far unused clocks actually get turned off.
