[PATCH] x86: fix PDA variables to work during boot

The current PDA code, which went in in post 2.6.19 has a flaw in that it
doesn't correctly cycle the GDT and %GS segment through the boot PDA,
the CPU PDA and finally the per-cpu PDA.

The bug generally doesn't show up if the boot CPU id is zero, but
everything falls apart for a non zero boot CPU id.  The basically kills
voyager which is perfectly capable of doing non zero CPU id boots, so
voyager currently won't boot without this.

The fix is to be careful and actually do the GDT setups correctly.

Different AX88772 dongles use different PHYs; the chip is capable of using
both a primary and secondary PHY, and supports an internal and external PHY.

It appears that some DUB-E100 devices use the internal PHY, so trying to use
an external one will not work (note that this is different across revisions,

sheet for the AX88772 chip specifies that the internal PHY id will be 0x10,

[POWERPC] atomic_dec_if_positive sign extension fix

On 64-bit machines, if an atomic counter is explicitly set to a
negative value, the atomic_dec_if_positive function will decrement and
store the next smallest value in the atomic counter, contrary to its
intended operation.

The comparison to determine if the decrement will make the result
negative was done by the "addic." instruction, which operates on a
64-bit value, namely the zero-extended word loaded from the atomic
variable.  This patch uses an explicit word compare (cmpwi) and
changes the addic. to an addi (also changing "=&r" to "=&b" so that r0
isn't used, and addi doesn't become li).

This also fixes a bug for both 32-bit and 64-bit in that previously
0x80000000 was considered positive, since the result after
decrementing is positive.  Now it is considered negative.

Also, I clarify the return value in the comments just to make it clear
that the value returned is always the decremented value, even if that
value is not stored back to the atomic counter.

[POWERPC] Fix broken DMA on non-LPAR pSeries

It appears that the iommu table address is never stored, and thus
never found, on non-lpar systems. Thus, for example, during boot:

<7>[   93.067916] PCI: Scanning bus 0001:41
<7>[   93.068542] PCI: Found 0001:41:01.0 [8086/100f] 000200 00

<7>[   93.070251] PCI: Bus scan for 0001:41 returning with max=41

No iommu table? How can that be? Well, circa line 471 of
arch/powerpc/platforms/pseries/iommu.c we see the code:

   while (dn && PCI_DN(dn) && PCI_DN(dn)->iommu_table == NULL)
      dn = dn->parent;

and a few lines later is the surprising print statement about
the missing table.  Seems that this loop ran unto the end, never
once finding a non-null PCI_DN(dn)->iommu_table.

The problem can be found a few lines earlier: it sems that the
value of PCI_DN(dn)->iommu_table is never ever set. Thus, the
patch sets it.

The patch was tested on a Power4 system running in full system
partition mode, which is where I saw the problem. It works; I've
not done any wider testing. Had a brief discussion on this on irc.

sata_mv HighPoint 2310 support (88SX7042)

With the following patch, my HighPoint 2310 with a Marvell 88SX7042 on
it seems to work OK.

The controller only has 4 ports, with MV_FLAG_DUAL_HC it seems to init 8
ports and fails miserably at probe time. There are no other devices mapped
to that chip, maybe it was just incorrectly specified in the first place?

17 years agolibata: fix handling of port actions in per-dev action mask

libata: fix handling of port actions in per-dev action mask

libata EH ignores port-wide actions in per-dev action mask.  However,
device resume requests EH_SOFTRESET using per-dev action mask.  Under
certain circumstances, this results in not resetting frozen port after
resuming which causes failure of all commands.

This patch allows port-wide actions to be requested in per-dev action
mask.  Before EH recovery starts, port-wide actions will be collected.

17 years agolibata: initialize qc->dma_dir to DMA_NONE
Tejun Heo [Wed, 17 Jan 2007 02:34:02 +0000 (11:34 +0900)]
libata: initialize qc->dma_dir to DMA_NONE

libata didn't used to init qc->dma_dir to any specific value on qc
initialization and command translation path didn't set qc->dma_dir if
the command doesn't need data transfer.  This made non-data commands
to have random qc->dma_dir.

This usually doesn't cause problem because LLDs usually check
qc->protocol first and look at qc->dma_dir iff the command needs data
transfer but this doesn't hold for all LLDs.

It might be worthwhile to rename qc->dma_dir to qc->data_dir as we use
the field to tag data direction for both PIO and DMA protocols.
