Subject: [RESEND PATCHv4 0/3] fpga: altera-cvp: Add Stratix10 Support
Date: Mon, 19 Aug 2019 15:48:05 -0500 [thread overview]
Message-ID: <1566247688-26070-1-git-send-email-thor.thayer@linux.intel.com> (raw)
From: Thor Thayer <thor.thayer@linux.intel.com>
Newer versions (V2) of Altera/Intel FPGAs CvP have different PCI
Vendor Specific Capability offsets than the older (V1) Altera/FPGAs.
Most of the CvP registers and their bitfields remain the same
between both the older parts and the newer parts.
This patchset implements changes to discover the Vendor Specific
Capability offset and then add Stratix10 CvP support.
V2 Changes:
Remove inline designator from abstraction functions.
Reverse Christmas Tree format for local variables
Remove redundant mask from credit calculation
Add commment for the delay(1) function in wait_for_credit()
V3 Changes
Return int instead of void for abstraction functions
Check the return code from read in altera_cvp_chk_error()
Move reset of current_credit_byte to clear_state().
Check return codes of read/writes in added functions.
V4 Changes
Rename delta_credit to space
Simplify wait for credit do-while loop.
Change from udelay() to usleep_range()
Use min() to find length to send
Remove NULL initialization from private structure
Use #define for Version1 offsets
Change current_credit_byte to u32 sent_packets.
Changes to Kconfig title and description to support Stratix10.
