From: Jason Gunthorpe <jgg at mellanox.com> Presumably the intent here was that hmm_range_fault() could put the data into some HW specific format and thus avoid some work. However, nothing actually does that, and it isn't clear how anything actually could do that as hmm_range_fault() provides CPU addresses which must be DMA mapped. Perhaps there is some special HW that does not need

From: Jason Gunthorpe <jgg at mellanox.com> The API is a bit complicated for the uses we actually have, and disucssions for simplifying have come up a number of times. This small series removes the customizable pfn format and simplifies the return code of hmm_range_fault() All the drivers are adjusted to process in the simplified format. I would appreciated tested-by's for the two

Hi Jérôme, Ben and Jason, below is a series against the hmm tree which fixes up the mmap_sem locking in nouveau and while at it also removes leftover legacy HMM APIs only used by nouveau.

Hello, I'm posting this again (with some small edits). I didn't get any replies last time...hoping for some this time. :) Currently I'm only coming up with brute force solutions to this issue (loops). I'm wondering if anyone has a better way to do this. Thank you for your help in advance! The problem: I have endpoints of one x range (x_rng) and an unknown number of s ranges

All users pass PAGE_SIZE here, and if we wanted to support single entries for huge pages we should really just add a HMM_FAULT_HUGEPAGE flag instead that uses the huge page size instead of having the caller calculate that size once, just for the hmm code to verify it.

The start, end and page_shift values are all saved in the range structure, so we might as well use that for argument passing.

Thank you for the explanation. Yes, it was a mistake to leave my two faxias that way, by the ID exchange reason the low range will leave as it was to have no problems idmap config SERVERAD: range = 5000-33554431 The range of up'm thinking of changing to something idmap config *: range = 2000-4500 Not to be superimposed. But it will it not cause problem ids trading again? Since it was

Hi Jérôme, Ben and Jason, below is a series against the hmm tree which fixes up the mmap_sem locking in nouveau and while at it also removes leftover legacy HMM APIs only used by nouveau. The first 4 patches are a bug fix for nouveau, which I suspect should go into this merge window even if the code is marked as staging, just to avoid people copying the breakage. Changes since v1: - don't

Here are seven more patches for things I found to clean up. This was based on top of Christoph's seven patches: "hmm_range_fault related fixes and legacy API removal v3". I assume this will go into Jason's tree since there will likely be more HMM changes in this cycle. Changes from v1 to v2: Added AMD GPU to hmm_update removal. Added 2 patches from Christoph. Added 2 patches as

When I run a macro that uses RExcel, I get a dialog box that says "Microsoft Excel is waiting for another application to complete an OLE action." There is no error in the RExcel commands in the macro, of that I am sure. The box appears to be related to the inclusion of RunRFile commands. The macro will run through the second RunRFile command, but will not execute the

I got it, so it must have been the problem .. Strange that changed it more than one month at least. Having these values now, how do you think I do? Leave it or change at least the idmap config * values: range? I understand the parameters: idmap config *: range = Range of the Ids are User system idmap config SERVERAD: range: DC User Range Thank you Em 13-07-2016 05:16, Rowland penny escreveu:
