Dear all, I have imported a dataset from Stata using the foreign package. The original data contain French characters such as è and ç . After importing, string variables containing names of French departments have changed. E.g. Ardèche became Ard\x8fche. I would like to ask how I could plot these changed strings, since now the strings with special characters fail to be printed in the plot (either

Hey Ard, It seems that Ben already committed a similar patch to his tree (see [0]). I do not know whether he is planning to have it part of a pull request of fixes for 4.15.

Commit be55287aa5b ("drm/nouveau/imem/nv50: embed nvkm_instobj directly into nv04_instobj") introduced some new calls to the refcount api to the nv50 mapping code. In one particular instance, it does the following: if (!refcount_inc_not_zero(&iobj->maps)) { ... refcount_inc(&iobj->maps); } i.e., it calls refcount_inc() to increment the

The 100c08 scratch page is mapped using dma_map_page() before the TTM layer has had a chance to set the DMA mask. This means we are still running with the default of 32 when this code executes, and this causes problems for platforms with no memory below 4 GB (such as AMD Seattle) So move the dma_map_page() to the .init hook, and set the streaming DMA mask based on the MMU subdev parameters before

This v4 is now a 3 piece series (since v4), after Alexandre pointed out that both GF 100 and NV50 are affected by the same issue, and that a related issue has been solved already for Tegra in commit 9d0394c6bed5 ("drm/nouveau/instmem/gk20a: set DMA mask early"). The issue that this series addresses is the fact that the Nouveau driver invokes the DMA API before setting the DMA mask. In

Hi Ard, the official nouveau tree is here: https://github.com/skeggsb/nouveau But ben usually takes care of everything if you post the patches on the ML. No idea what you discussed internally though, but alex also posts his suff here.
