We constrain cosmology and baryonic feedback scenarios with a joint analysisof weak lensing, galaxy clustering, cosmic microwave background (CMB) lensing,and their cross-correlations (so-called 6$\times$2) using data from the DarkEnergy Survey (DES) Y1 and the Planck satellite mission. Noteworthy features ofour 6$\times$2 pipeline are: We extend CMB lensing cross-correlationmeasurements to a band surrounding the DES Y1 footprint (a $\sim 25\%$ gain inpairs), and we develop analytic covariance capabilities that account fordifferent footprints and all cross-terms in the 6$\times$2 analysis. We alsomeasure the DES Y1 cosmic shear two-point correlation function (2PCF) down to$0.^\prime 25$, but find that going below $2.^\prime 5$ does not increasecosmological information due to shape noise. We model baryonic physicsuncertainties via the amplitude of Principal Components (PCs) derived from aset of hydro-simulations. Given our statistical uncertainties, varying thefirst PC amplitude $Q_1$ is sufficient to model small-scale cosmic shear 2PCF.For DES Y1+Planck 6$\times$2 we find $S_8=0.799\pm0.016$, comparable to the5$\times$2 result of DES Y3+SPT/Planck $S_8=0.773\pm0.016$. Combined with ourmost informative cosmology priors -- baryon acoustic oscillation (BAO), bigbang nucleosynthesis (BBN), type Ia supernovae (SNe Ia), and Planck 2018EE+lowE, we measure $S_8=0.817\pm 0.011$. Regarding baryonic physicsconstraints, our 6$\times$2 analysis finds $Q_1=2.8\pm1.8$. Combined with theaforementioned priors, it improves the constraint to $Q_1=3.5\pm1.3$. Forcomparison, the strongest feedback scenario considered in this paper, thecosmo-OWLS AGN ($\Delta T_\mathrm{heat}=10^{8.7}$ K), corresponds to$Q_1=5.84$.
