<html><body><p>Hey Stewart,<br><br>I was able to work on the XZ changes and recently got it merged and reviewed:<br> Hostboot p8 review: <a href="https://ralgit01.raleigh.ibm.com/gerrit1/#/c/24609/">https://ralgit01.raleigh.ibm.com/gerrit1/#/c/24609/</a><br> Op-build pull request: <a href="https://github.com/open-power/op-build/pull/520">https://github.com/open-power/op-build/pull/520</a><br> Open-power/pnor pull request: <a href="https://github.com/open-power/pnor/pull/48">https://github.com/open-power/pnor/pull/48</a><br><br>So now, you should be able to compress and decompress a section without additional pnor changes with op-build/master-next. However we currently are not automatically processing if a section is compressed or not, so if you need hostboot to decompress the image, I'll have to add in some additional functionality. The skiboot image will be processed though. Let me know if you have any trouble with the compression/decompression or if you want to add in another section.<br><br>Also, here's the compression command that works with the xz decompressor: <font size="2" color="#183691" face="Consolas">xz --check=crc32 </font><font size="2" color="#333333" face="Consolas">$image</font><font size="4"> </font><br><br>Best,<br>Elizabeth<br>--<br>Elizabeth Liner<br>Power Firmware Development - Hostboot<br>IBM Systems & Technology Group - Austin, TX<br>eliner@us.ibm.com<br>512-286-6493<br><br><br><img width="16" height="16" src="cid:1__=8FBBF57DDFDE43D58f9e8a93df938690918c8FB@" border="0" alt="Inactive hide details for Stewart Smith ---05/10/2016 08:55:18 PM---Elizabeth Liner <eliner@us.ibm.com> writes: > I'm hoping to"><font color="#424282">Stewart Smith ---05/10/2016 08:55:18 PM---Elizabeth Liner <eliner@us.ibm.com> writes: > I'm hoping to get to the changes some time this month,</font><br><br><font size="2" color="#5F5F5F">From: </font><font size="2">Stewart Smith <stewart@linux.vnet.ibm.com></font><br><font size="2" color="#5F5F5F">To: </font><font size="2">Elizabeth Liner/Austin/IBM@IBMUS</font><br><font size="2" color="#5F5F5F">Cc: </font><font size="2">Cédric Le Goater <clg@fr.ibm.com>, skiboot@lists.ozlabs.org</font><br><font size="2" color="#5F5F5F">Date: </font><font size="2">05/10/2016 08:55 PM</font><br><font size="2" color="#5F5F5F">Subject: </font><font size="2">Re: [RFC PATCH 1/2] config: introduce CONFIG_FSP in Makefiles</font><br><hr width="100%" size="2" align="left" noshade style="color:#8091A5; "><br><br><br><tt>Elizabeth Liner <eliner@us.ibm.com> writes:<br>> I'm hoping to get to the changes some time this month, but I'm not sure if<br>> I have the time at this moment.<br>> However, I can try to make this a priority if you think it would be useful<br>> for the skiboot team.<br><br>It would be useful - even in just a testing capacity, as I'd like to<br>start doing test runs with a GCOV enabled skiboot so that we can get<br>code coverage data out of op-test-framework.
