Subject: [PATCH v3 0/4] Expose GT CNTFRQ as a CPU property to support AST2600
Date: Fri, 13 Dec 2019 16:19:47 +1030 [thread overview]
Message-ID: <cover.ec85a2db47c3e10de70fba144e1bc75caf2f0a91.1576215453.git-series.andrew@aj.id.au> (raw)
Hello,
This is a v3 of the belated follow-up from a few of my earlier attempts to fix
up the ARM generic timer for correct behaviour on the ASPEED AST2600 SoC. The
AST2600 clocks the generic timer at the rate of HPLL, which is configured to
1125MHz. This is significantly quicker than the currently hard-coded generic
timer rate of 62.5MHz and so we see "sticky" behaviour in the guest.
v2 can be found here:
https://patchwork.ozlabs.org/cover/1203474/
Changes since v2:
* Address some minor review comments from Philippe and add tags
Changes since v1:
* Fix a user mode build failure from partial renaming of gt_cntfrq_period_ns()
* Add tags from Cedric and Richard
Please review.
Andrew
