| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Cadence I2C controller has bug wherein it generates invalid read transactions after timeout in master receiver mode. This driver does not use the HW timeout and this interrupt is disabled but the feature itself cannot be disabled. Hence, this patch writes the maximum value (0xFF) to this register. This is one of the workarounds to this bug and it will not avoid the issue completely but reduces the chances of error.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to I2C specification the NACK should be handled as follows: "When SDA remains HIGH during this ninth clock pulse, this is defined as the Not Acknowledge signal. The master can then generate either a STOP condition to abort the transfer, or a repeated START condition to start a new transfer." [I2C spec Rev. 6, 3.1.6: http://www.nxp.com/documents/user_manual/UM10204.pdf] Currently the Davinci i2c driver interrupts the transfer on receipt of a NACK but fails to send a STOP in some situations and so makes the bus stuck until next I2C IP reset (idle/enable). For example, the issue will happen during SMBus read transfer which consists from two i2c messages write command/address and read data: S Slave Address Wr A Command Code A Sr Slave Address Rd A D1..Dn A P <--- write -----------------------> <--- read ---------------------> The I2C client device will send NACK if it can't recognize "Command Code" and it's expected from I2C master to generate STP in this case. But now, Davinci i2C driver will just exit with -EREMOTEIO and STP will not be generated. Hence, fix it by generating Stop condition (STP) always when NACK is received. This patch fixes Davinci I2C in the same way it was done for OMAP I2C commit cda2109a26eb ("i2c: omap: query STP always when NACK is received").

It was important to reapply them, though, because of for example Haswell's TSX erratum which disabled TSX instructions with a microcode patch. A simple fix was fb86b97300d9 ("x86, microcode: Update BSPs microcode on resume") but, as it is often the case, simple fixes are too simple. This one causes 32-bit resume to fail: https://bugzilla.kernel.org/show_bug.cgi?id=88391 Properly fixing this would require more involved changes for which it is too late now, right before the merge window. Thus, limit this to 64-bit only temporarily.

So for a change let's see what happens when we don't re-enable pch fifo underrun reporting when the pipe is disabled. This means that the kernel can't catch pch fifo underruns when they happen (except when all pipes are on on the pch). But we'll still catch underruns when disabling the pipe again. So not a terrible reduction in test coverage. Since the DRM_ERROR is new and hence a regression plan B would be to revert it back to a debug output. Which would be a lot worse than this hack for underrun test coverage in the wild. See the referenced discussions for more.

XRDY or ARDY interrupts will be fired again. As a result, ISR keep processing transfer after it was already complete (from the driver code point of view). A didn't see real impacts of the 1d7afc9, but it is really bad idea to have ISR running on user data after transfer was complete. It looks, what 1d7afc9 violate TI specs in what how AL and NACK should be handled (see Note 1, sprugn4r, Figure 17-31 and Figure 17-32). According to specs (if I understood correctly), in case of NACK and AL driver must reset NACK, AL, ARDY, RDR, and RRDY (Master Receive Mode), and NACK, AL, ARDY, and XDR (Master Transmitter Mode). All that is done down the code under the if condition: if (stat & (OMAP_I2C_STAT_ARDY | OMAP_I2C_STAT_NACK | OMAP_I2C_STAT_AL)) ... The patch restore pre 1d7afc9 logic of handling NACK and AL interrupts, so no interrupts is fired after ISR informs the rest of driver what transfer complete. Note: instead of removing break under NACK case, we could just replace 'break' with 'continue' and allow NACK transfer to finish using ARDY event. I found that NACK and ARDY bits usually set together. That case confirm TI wiki: http://processors.wiki.ti.com/index.php/I2C_Tips#Detecting_and_handling_NACK In order if someone interested in the event traces for NACK and AL cases, I sent them to mailing list.

Rather than containing the physical address of the I/O region, the addresses will now be in I/O address space. On Tegra the union of all ranges is used to expose a top-level memory- mapped resource for the PCI host bridge. This helps to make /proc/iomem more readable. Combining both of the above, the union would now include the I/O space region. This causes a regression on Tegra20, where the physical base address of the PCIe controller (and therefore of the union) is located at physical address 0x80000000. Since I/O space starts at 0, the union will now include all of system RAM which starts at 0x00000000. This commit fixes this by keeping two copies of the I/O range: one that represents the range in the CPU's physical address space, the other for the range in the I/O address space. This allows the translation setup within the driver to reuse the physical addresses. The code registering the I/O region with the PCI core uses both ranges to establish the mapping.

I debated whether or not to send you this merge request because we're at such a late rc. The bug isn't critical in that there is only one system known to be affected and the patch is easy to backport. The codepath is used by pretty much every DT based system, so there is risk a of regression (it /should/ be safe, but I've been bitten by stuff that should be safe before). I've had it in linux-next for a week and haven't received any complaints. I think it probably should just be merged right away rather than waiting for the merge window and backporting. It does fix a real bug and the code is theoretically safer after the change. I can't think of any situation where it would be dangerous to reserve the DT memory an extra time.

This call was introduced as part of d1552ce449eb "of/fdt: move memreserve and dtb memory reservations into core" which went into v3.16. I observed this causing a Midway system with a buggy fdt (the header declares itself to be larger than it really is) failing to boot because the over-inflated size of the fdt was causing it to seem to run into the swapper_pg_dir region, meaning the DT wasn't reserved. The symptoms were failing to find an disks or network and failing to boot. However given the ambiguity of whether things like the initrd are covered by /memreserve/ and similar I think it is best to also register the region rather than just ignoring it. Since memblock_reserve() handles overlaps just fine lets just warn and carry on.

However, the clone bio has bi_vcnt == 0, which means that when the sd driver calls bio_integrity_process to attach DIX data, the for_each_segment_all() call (which uses bi_vcnt) returns immediately and random garbage is sent to the disk on a disk write. The disk of course returns an error. Therefore, teach bio_integrity_process() to use bio_for_each_segment() to iterate the bio_vecs, since the per-bio iterator tracks which bio_vecs are associated with that particular bio. The integrity handling code is effectively part of the "driver" (it's not the bio owner), so it must use the correct iterator function. v2: Fix a compiler warning about abandoned local variables. This patch supersedes "block: bio_integrity_process uses wrong bio_vec iterator". Patch applies against 3.18-rc6. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Acked-by: Martin K.
