Rather than building a config which may or may not work, let the driver build an initial fb config. This allows the driver to use the BIOS boot configuration for example, displaying kernel messages and the initial fb console on the same outputs the BIOS lit up at boot time. If that fails, the driver can still fall back the same way as the core.

In the case where the hardware has been wrongly programmed and the EDP TRANS_DDI_FUNC_CTL register has a bogus value in its EDP Input field, we were using the pipe variable uninitialized. In this case, shutdown the transcoder. It will be programmed correctly the next time we try to enabled eDP.

Change the gen6+ max delay if the pcode read was successful (not the inverse). The previous code was all sorts of wrong and has existed since I broke it: commit 42c0526c Author: Ben Widawsky <ben@bwidawsk.net> Date: Wed Sep 26 10:34:00 2012 -0700 drm/i915: Extract PCU communication I added some parentheses for clarity, and I also corrected the debug message message to use the mask (wrong before I came along) and added a print to show the value we're changing from. Looking over the code, I'm not actually sure what we're trying to do. I introduced the bug simply by extracting the function not implementing anything new. We already set max_delay based on the capabilities register (which is what we use elsewhere to determine min and max). This would potentially increase it, I suppose? Jesse, I can't find the document which explains the definitions of the pcode commands, maybe you have it around. Based on Jesse's response, this could potentially be for -fixes, or stable, or maybe lead to us dropping it entirely. As the current code is is, things won't completely break because of the aforementioned capabilities register, and in my experimentation, enabling this has no effect, it goes from 1100->1100. I found this while reviewing Jesse's VLV patches.

It fixes the issue arises due to passing 'nr_pages' in place of 'nents' to sg_alloc_table. When ARM_HAS_SG_CHAIN is disabled, it is causing failure in creating SG table for the buffers having more than 204 physical pages i.e. equal to SG_MAX_SINGLE_ALLOC. When using sg_alloc_table_from_pages interface, in place of sg_alloc_table, page list will be passes to get each contiguous section which is represented by a single entry in the table. For a Contiguous Buffer, number of entries should be equal to 1. Following check is causing the failure which is not applicable for Non-Contig buffers: if (WARN_ON_ONCE(nents > max_ents)) return -EINVAL; Above patch is well tested for EXYNOS4 and EXYNOS5 for with/wihtout IOMMU supprot. NOUVEAU and RADEON platforms also depends on drm_prime_pages_to_sg helper function.

So far we created a sparse dma scatter list for gem objects, where each scatter list entry represented only a single page. In the future we'll have to handle compact scatter lists too where each entry can consist of multiple pages, for example for objects imported through PRIME. The previous patches have already fixed up all other places where the i915 driver _walked_ these lists. Here we have the corresponding fix to _create_ compact lists. It's not a performance or memory footprint improvement, but it helps to better exercise the new logic.

This might not hold in the future, when we'll introduce compact scatter lists, so prepare for this everywhere in the i915 code where we walk such a list.

This is needed since currently sg_for_each_page assumes that we have a valid page in each sg item. It is only a real problem for CONFIG_SPARSEMEM where the page is dereferenced, in other cases the iterator works ok with an invalid page pointer. We can remove this workaround when we have fixed sg_page_iter to work on scatterlists without backing pages. Signed-off-by: NImre Deak <imre.deak@intel.com>
