1Subject: [v2,1/3] ARM: OMAP2+: am43xx: Use omap4 prm context ops
2Date: Sat, 15 Feb 2014 02:07:33 -0000
3From: Dave Gerlach <d-gerlach@ti.com>
4
5Context loss counting relies on several prm function pointers that
6serve as a "mapping" into the context loss registers and actually
7allow reading and clearing of the registers. Use the same
8from omap4 for am43xx as the layout of the prcm is similar.

1Subject: [v2,2/3] ARM: OMAP2+: omap_hwmod: Add context ops to am43xx soc_ops
2Date: Sat, 15 Feb 2014 02:07:34 -0000
3From: Dave Gerlach <d-gerlach@ti.com>
4
5AM43XX contains PRM_*_CONTEXT registers like OMAP4 did to track loss
6of context in modules so utilize the same get_context_loss_count soc_op
7present for OMAP4 but define a custom update context loss function for
8am43xx. Because we do not define context_offs for each hwmod, introduce
9a new flag to indicate when we have so we only bother to update when
10we know that it is valid.
11
12Certain drivers use the context loss count to determine if context was
13truly lost during a suspend operation to decide whether or not a
14context restore is truly necessary. Without this, some drivers may
15choose not to restore context when they have actually lost it and fail
16to properly resume.

4Subject: [PATCH 2/6] ARM: config: omap: Make advanced networking features as
5 modules
6
7Linux networking supports advanced networking features like IPSEC, NETFILTERS,
8BRIDGING etc and should be enabled only when user has specific usecase to
9use them. Thats why all typical distro's build them as modules so that all
10the standard network usecases don't get any additional overhead and specific
11case can load those modules when needed.
12
13Lets align the config accordingly. Created using typical 'savedefconfig' method.

1Subject: [v2,3/3] ARM: OMAP2+: am43xx: Add context offset for dss hwmod
2Date: Sat, 15 Feb 2014 02:07:35 -0000
3From: Dave Gerlach <d-gerlach@ti.com>
4
5Add context_offs to the DSS hwmod for am43xx as the driver uses the
6context loss count to determine whether or not to restore context to the
7module. Also add prcm flag indicating this bit is valid. Without this the
8display does not return after a suspend cycle.

4Subject: [PATCH 3/6] ARM: config: omap: Disable extra debug options
5
6LOCK debug, SCHED debug, PREEMPT debug are very expensive operations and
7always in fast path of kernel operations. These are typical kernel development
8options and should be disabled in production kernel builds.
9
10Also enable JUMP_LABEL to take advantage of compiler optimisations.
11
12Created using typical 'savedefconfig' method. Hence you see some crypto
13option noise which unrelated and no impact on the end config.

5In the case of am43xx, make sure we allow hwmods that don't use the hwmod
6context_offs for context loss counting to still use powerdomains to count
7context loss.

4Subject: [PATCH 4/6] Not-for-merge: ARM: config: omap: Disable SMP for AM335x
5 build
6
7SMP and SMP_ON_UP introduces some extra barriers and code many fast paths
8including kernel lock functions.
9
10Performance sensitive usecases like networking gets impacted because of this.
11In typical production kernel which is targeted for single core device
12like AM335x family, you don't want to take this hit.
13
14Ideally one should just create a device specific config feed as done by all
15typical distro's. Other option is to apply this specifically during build
16time using recipe.
17
18Whichever option, one definitely don't want this overhead for performance
19critical usecases.
20
21Disabling SMP in the build introduces one warining in cpuidle44xx.c driver
22and fix is included in the series
