|
|
There are three important fields that indicate the overall health and
status of an array: dev_health, sync_ratio, and sync_action. They tell
us the condition of the devices in the array, and the degree to which
the array is synchronized.
This commit fixes a condition that is reported incorrectly. When a member
of the array is being rebuilt or a new device is added, the "recover"
process is used to synchronize it with the rest of the array. When the
process is complete, but the sync thread hasn't yet been reaped, it is
possible for the state of MD to be:
mddev->recovery = [ MD_RECOVERY_RUNNING MD_RECOVERY_RECOVER MD_RECOVERY_DONE ]
curr_resync_completed = <max dev size> (but not MaxSector)
and all rdevs to be In_sync.
This causes the 'array_in_sync' output parameter that is passed to
rs_get_progress() to be computed incorrectly and reported as 'false' --
or not in-sync. This in turn causes the dev_health status characters to
be reported as all 'a', rather than the proper 'A'.
This can cause erroneous output for several seconds at a time when tools
will want to be checking the condition due to events that are raised at
the end of a sync process. Fix this by properly calculating the
'array_in_sync' return parameter in rs_get_progress().
Also, remove an unnecessary intermediate 'recovery_cp' variable in
rs_get_progress().

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Olof Johansson:
"Our first batch of fixes this release cycle, unfortunately a bit
noisier than usual. Two major groups stand out:
- Some pinctril dts/dtsi changes for stm32 due to a new driver being
merged during the merge window, and this aligns the DT contents
between the old format and the new. This could arguably be moved to
the next merge window but it also seemed relatively harmless to
include now.
- Amlogic/meson had driver changes merged that required devicetree
changes to avoid functional/performance regressions. I've already
asked them to be more careful about this going forward, and making
sure drivers are compatible with older DTs when they make these
kind of changes. The platform is actively being upstreamed so
there's a few things in flight, we've seen this happen before and
sometimes it's hard to catch in time.
Besides that there is the usual mix of minor fixes"

commit f6810c15cf97 ("iommu/arm-smmu: Clean up early-probing
workarounds") removed kernel code that was allowing to initialize
and probe the SMMU devices early (ie earlier than PCI devices, through
linker script callback entries) in the boot process because it was not
needed any longer in that the SMMU devices/drivers now support deferred
probing.
Since the SMMUs probe routines are also in charge of requesting global
PCI ACS kernel enablement, commit f6810c15cf97 ("iommu/arm-smmu: Clean
up early-probing workarounds") also postponed PCI ACS enablement to
SMMUs devices probe time, which is too late given that PCI devices needs
to detect if PCI ACS is enabled to init the respective capability
through the following call path:
pci_device_add()
-> pci_init_capabilities()
-> pci_enable_acs()
Add code in the ACPI IORT SMMU platform devices initialization path
(that is called before ACPI PCI enumeration) to detect if there
exists firmware mappings to map root complexes ids to SMMU ids
and if so enable ACS for the system.

Currently, NVMe PCI host driver is programming CMB dma address as
I/O SQs addresses. This results in failures on systems where 1:1
outbound mapping is not used (example Broadcom iProc SOCs) because
CMB BAR will be progammed with PCI bus address but NVMe PCI EP will
try to access CMB using dma address.
To have CMB working on systems without 1:1 outbound mapping, we
program PCI bus address for I/O SQs instead of dma address. This
approach will work on systems with/without 1:1 outbound mapping.
Based on a report and previous patch from Abhishek Shah.

Resetting the phase when POWER_ON is set the set_ios() call means that the
phase is reset almost every time the set_ios() is called, while the
expected behavior was to reset the phase on a power cycle.
This had gone unnoticed until now because in all mode (except hs400) the
tuning is done after the last to set_ios(). In such case, the tuning
result is used anyway. In HS400, there are a few calls to set_ios() after
the tuning is done, overwriting the tuning result.
Resetting the phase on POWER_UP instead of POWER_ON solve the problem.

In may, Steven sent a patch deleting the bounce buffer handling
and the CONFIG_MMC_BLOCK_BOUNCE option.
I chose the less invasive path of making it a runtime config
option, and we merged that successfully for kernel v4.12.
The code is however just standing in the way and taking up
space for seemingly no gain on any systems in wide use today.
Pierre says the code was there to improve speed on TI SDHCI
controllers on certain HP laptops and possibly some Ricoh
controllers as well. Early SDHCI controllers lacked the
scatter-gather feature, which made software bounce buffers
a significant speed boost.
We are clearly talking about the list of SDHCI PCI-based
MMC/SD card readers found in the pci_ids[] list in
drivers/mmc/host/sdhci-pci-core.c.
The TI SDHCI derivative is not supported by the upstream
kernel. This leaves the Ricoh.
What we can however notice is that the x86 defconfigs in the
kernel did not enable CONFIG_MMC_BLOCK_BOUNCE option, which
means that any such laptop would have to have a custom
configured kernel to actually take advantage of this
bounce buffer speed-up. It simply seems like there was
a speed optimization for the Ricoh controllers that noone
was using. (I have not checked the distro defconfigs but
I am pretty sure the situation is the same there.)
Bounce buffers increased performance on the OMAP HSMMC
at one point, and was part of the original submission in
commit a45c6cb81647 ("[ARM] 5369/1: omap mmc: Add new
omap hsmmc controller for 2430 and 34xx, v3")
This optimization was removed in
commit 0ccd76d4c236 ("omap_hsmmc: Implement scatter-gather
emulation")
which found that scatter-gather emulation provided even
better performance.
The same was introduced for SDHCI in
commit 2134a922c6e7 ("sdhci: scatter-gather (ADMA) support")
I am pretty positively convinced that software
scatter-gather emulation will do for any host controller what
the bounce buffers were doing. Essentially, the bounce buffer
was a reimplementation of software scatter-gather-emulation in
the MMC subsystem, and it should be done away with.

Locking of config and doorbell operations should be done only if the
underlying hardware requires it.
This patch removes the global spinlocks from the rapidio subsystem and
moves them to the mport drivers (fsl_rio and tsi721), only to the
necessary places. For example, local config space read and write
operations (lcread/lcwrite) are atomic in all existing drivers, so there
should be no need for locking, while the cread/cwrite operations which
generate maintenance transactions need to be synchronized with a lock.
Later, each driver could chose to use a per-port lock instead of a
global one, or even more granular locking.

The common lane power down flag of a DPIO PHY has a funky semantic:
after the initial enabling of the PHY (so from a disabled state) this
flag will be clear. It will be set only after the PHY will be used for
the first time (for instance due to enabling the corresponding pipe) and
then become unused (due to disabling the pipe). During the initial PHY
enablement we don't know which of the above phases we are in, so move
the check for the flag where this is known, the HW readout code. This is
where the rest of lane power down status checks are done anyway.
This fixes at least a problem on GLK where after module reloading, the
common lane power down flag of PHY1 is set, but the PHY is actually
powered-on and properly set up. The GRC readout code for other PHYs will
hence think that PHY1 is not powered initially and disable it after the
GRC readout. This will cause the AUX power well related to PHY1 to get
disabled in a stuck state, timing out when we try to enable it later.

We used to assign IRQs for all devices at boot-time, before any drivers
claimed devices. The following commits:
30fdfb929e82 ("PCI: Add a call to pci_assign_irq() in pci_device_probe()")
0e4c2eeb758a ("alpha/PCI: Replace pci_fixup_irqs() call with host bridge IRQ mapping hooks")
changed this so we now call pci_assign_irq() from pci_device_probe() when
we call a driver's probe method.
The ide_scan_pcibus() path (enabled by CONFIG_IDEPCI_PCIBUS_ORDER) bypasses
pci_device_probe() so it can guarantee devices are claimed in order of PCI
bus address. It calls the driver's probe method directly, so it misses the
pci_assign_irq() call (and other PCI initialization functions), which
causes failures like this:
