It creates a file per MSIC in /sys/kernel/debug/powerpc, which allows the user to trigger a fake MSI interrupt by writing to the file. This can be used to test some of the MSI generation path. In particular, that the MSIC recognises a write to the MSI address, generates an interrupt and writes the MSI packet into the ring buffer. All the code is inside #ifdef DEBUG so it causes no harm unless it's enabled.

Its possible to build the phylib as a module, however this breaks the board level fix ups because phy_read and phy_write are not available if we build as a module. So we unconditionally select PHYLIB to ensure its built into the kernel if we are building in MPC85xx MDS support. This was determined to be the easiest soultion even though it prevents the user from removing PHYLIB support if they decide they don't want it.

From: Anton Vorontsov Date: Fri, 23 May 2008 20:39:01 +0400 Subject: powerpc/83xx: new board support: MPC8360E-RDK This is patch adds board file, device tree, and defconfig for the new board, made by Freescale Semiconductor Inc. and Logic Product Development. Currently supported: 1. UEC{1,2,7,4}; 2. I2C; 3. SPI; 4. NS16550 serial; 5. PCI and miniPCI; 6. Intel NOR StrataFlash X16 64Mbit PC28F640P30T85; 7. Graphics controller, Fujitsu MB86277. Not supported in this patch: 1. StMICRO NAND512W3A2BN6E, 512 Mbit (supported with FSL UPM NAND driver); 2. FHCI USB (supported with FHCI driver). 3. QE Serial UCCs (tested to not work with ucc_uart driver, reason unknown, yet); 4. ADC AD7843 (tested to work, but support via device tree depends on major SPI rework, GPIO API, etc); Signed-off-by: Anton Vorontsov Signed-off-by: Kumar Gala --- arch/powerpc/boot/dts/mpc836x_rdk.dts

This patch cleans up the interrupt handler and erroneous tests in spu_stopped. It also removes the fields from the csa since it is not needed to process class 0 events.

This hurts the performance of HPC programs that access eHCA from userspace. With this patch, the kernel will only demote the slice(s) containing the eHCA or cache-inhibited mappings, leaving the remaining slices able to use 64kB hardware pages. This also changes the slice_get_unmapped_area code so that it is willing to place a 64k-page mapping into (or across) a 4k-page slice if there is no better alternative, i.e. if the program specified MAP_FIXED or if there is not sufficient space available in slices that are either empty or already have 64k-page mappings in them.

In some circumstances it would be nice to be able to create the instruction and patch it later, and also some code might want to check for errors in the branch creation before doing the patching. A future commit will change create_branch() to check for errors. For callers that don't care, replace create_branch() with patch_branch(), which just creates the branch and patches it directly. While we're touching all the callers, change to using unsigned int *, as this seems to match usage better. That allows (and requires) us to remove the volatile in the definition of vector in powermac/smp.c and mpc86xx_smp.c, that's correct because now that we're passing vector as an unsigned int * the compiler knows that it's value might change across the patch_branch() call.

The drc index should not be used for this as it will, and did, break. Until this point, systems that have had memory represented in the device tree with a node for each lmb the drc index would (luckily) closely track the base address of the lmb. For example a lmb with a drc index of 8000000a would have a base address of a0000000. This correlation allowed the current code to derive the starting page frame number from the drc inddex Device tree layouts where lmbs are represented under the ibm,dynamic-reconfiguration-memory node in the ibm,dynamic-memory property do not have this correlation between the drc index and base address of the lmb.

This change is needed because of the change in the way memory is represented under the ibm,dynamic-reconfiguration-memory node. All lmbs are described in the ibm,dynamic-memory property instead of having a separate node for each lmb as in previous device tree layouts. This requires the update_node() routine to check for updates to the ibm,dynamic-memory property and invoke the hotplug notifier chain. This also updates the pseries hotplug notifier to be able to gather information for lmbs represented under the ibm,dynamic-reconfiguration-memory node and have the lmbs added/removed.

The MPC8536 is an e500v2 based SoC which eTSEC, USB, SATA, PCI, and PCIe. The USB and SATA IP blocks are similiar to those on the PQ2 Pro SoCs and thus use the same drivers.

18:06:13 +0200 Subject: powerpc/CPM: Add i2c pins to dts and board setup Initialize I2C pins on boards with CPM1/CPM2 controllers and document the i2c bus in booting-without-of. The boards don't have any I2C chips connected to the I2C bus, so unless some external chips are connected to the boards, this code is just an example of setting everything else up.

In fact, even if that were not the case, there doesn't seem to be any place where G is set without also setting I (_PAGE_NO_CACHE), so the test for I is sufficient as a condition to clear _PAGE_COHERENT when filling the hash table.
